I bought the bike engine kit on wish.com but it took a month or so to arrive. Here's a like to one I found on Amazon: 2 stroke bike kit: amzn.to/31i5M6W Recommend shopping around for the best price! Thank you, Todd
This video is 2 years old and you still read and reply to comments posted 1 day ago, you’re the most underrated content creators on YT and you have my up most respect
I’m 75yrs old & in 1962 I started as a trainee motor mechanic when 2stroke engines were legal here in England the Southwest in a town called Taunton in the county of Somerset . . . . . . I found this video extremely interesting & have great admiration for the author/mechanic . . . . I’d love to have been able to have met & worked with this dude . . Jim .
Aloha Jim , I live in Hawyee and wanted to say " hi mate" ! Great to be able to say hi to someone thousands of miles away ! Blessing to you all in Britain !
Hi Jim, you make out 2 strokes are banned, they aren't 🤦♂️ Admittedly there are more 4 strokers now due to Chinese crap that stop working after a while. Hi from not faraway Wiltshire 🍺
They are illegal in NYC and in most localities in NY but if you aren't endangering others then most cops in smaller townships will leave you alone I had one of these and I cannot understate how dangerous they are. If you get one get at least a motorcycle helmet, motorcycle gloves, thick pants and only ride with your arms covered (at least a hoodie).
@@avipishy1710 I've had one for a few months now, if you're responsible with them they aren't very dangerous. The people around you are more likely to harm you than the bike is. Keep in mind, I'm fourteen years of age.
I daily drove one of these for almost two years. I got the 80cc kit for about $125. The only issue I had was a cracked top plate. I want to call it a head but it's not really. Anyway yeah it was absolutely terrifying to ride at 40mph on a rickety pawn shop bike. But honestly it was worth it.
@@tomboland6877 you definitely won’t want to touch it but it has fins on it so it is air cooled so as long as your moving and not just sitting there for a while reving it it will stay cool but still don’t touch it
@@ProjectFarm I have actually reached 55mph with mine and I believe with some tweaking it could probably go over 60mph. Mine is an 80cc on a mountain bike. It has a high compression head with an expansion chamber muffler.
4th year after trusting your review and buying one of those kits here. It still runs flawlessly after a lot of abuse and neglect both in trail and regular commute. The only thing that failed after first year was the stock chain, stretching up to the point of sagging (replaced with garage door chain, which only stretched by 1 link in 3rd year so far). This thing really changed my life becoming my main way of mid-long range transport (Especially great for hauling bags of potatoes when 2 large milk and bread crates are installed. My heart would probably give up on regular bike if I tried to move all of that around). Thanks.
My grandfather from NJ got me involved in motorized bicycle kits. He had a 2-stroke that sat on the front of the 10-speed and used friction against the tire to run the bike. I would always ride this contraption when I would visit him as a kid. I was enthralled. A few years later I saved enough grass cutting and snow shoveling money to buy a kit that Sears had. The kit used the same method of drive and after a few years and many friction wheels replaced I graduated to a moped and finally motorcycles. Good memories. Thanks for making this video. 😉
When I was a kid, I lived in Iran (1958-1960) and I saw quite a few bicycles puttering about with 2 stroke motors affixed to the handlebars. Everything there is very much spread out, and hot, and dry. You could get heat stroke pedaling from village to village (I lived in a little port town called Abidan) but the guys I saw riding these contraptions looked quite pleased with themselves.
@@auturgicflosculator2183 My hometown is Los Angeles, California. You're talking about the difference between Texas cucumbers and California peas (some people call them watermelons.)
What I love the most about your videos is, you get straight to the point and dont try to fluff the length of the video, this is the quality content I appreciate.
Hey Todd! To minimize the engine vibration, get an old tire and cut it into strips. Use the strips between the engine and the frame to prevent engine vibrations from being transferred to the frame. Anything rigid connecting the engine to the frame (chain guard, muffler, etc) should be isolated from the frame as well. Thanks for your service!
Some pointers for people who're interested in using one of these based on my experience of about 2000 miles: I built a bike with a 49cc varient of this engine back in 2011 and used it for going to college. I used a steel frame to avoid the metal fatigue the vibrations would cause to some aluminium frames making them weaker. Even painted it and did a 100% custom job, she was a lovely yoke to potter around on here in Ireland. -The slang term on the internet for this specific engine is called a "happy time engine" because very few of them last beyond 2500 to 3500 miles due to poor quality components. -Heavier bike frames are more suitable and lighter ones(i.e. racing bikes) have less material to support these. -Disc brakes on at least the front are really mandatory because in the rain standard bicycle brakes will seem absolutely terrifying, trust me on that. I installed a 180mm hydraulic disc brake on the front personally. -Replace the chinese spark plug straight away, they suck. -The original spark plug caps are also terrible, I bought an NGK one for 5 euro in a motorbike shop. -I ran 25:1 after the break in and accepted spark plug cleaning duties to increase engine life. -The front left engine cover is highly prone to water ingress and in light rain was caused the electrical system to fail on me twice meaning I've had to replace the stator. If I was building another one I'd drill a hole on the bottom of that compartment for drainage and seal up the rest of it even better than I already did. -The clutch arm actuates a pin inside the engines sprocket that relies on that sprocket cover being on very tight. The pin and arm are made of very poor quality steel and it's a completely dry metal to metal contact so I highly advise regualr grasing of it and carrying some kind of screwdriver to tighten the cover if it gets loose or you'll be pedeling a very heavy bicycle home very slowly. -The exhausts and their bolts can rust very quickly if not looked after. -The petol tanks 4 studs are low quality and directly welded to the tank so they strip easiliy. -Bring a small pre measured bottle of 2 stroke oil with you so you can just dump it into the petrol tank when empty and fill up at any petrol station. -Ensure the carb screws are set correctly. -Do not use off road tyres on paved roads. I had a small accident because extra weight + low traction + slight leaning = bad time. -Hgher tyre pressures than normal are required for the excess weight. I stopped using mine in Ireland in 2012 as the laws were changed and the motorized bicycle then fell into the category of a moped even though it was under 50cc. Fail to follow tthe laws where you live at your own peril. If any of you guys have any questions that I haven't answered already I don't mind.
If you install a front disc brake, you need a fork that will support it: standard forks will bend from the force put on the caliper. If you don't mind building a wheel, a drum brake is a good alternative.
By watching this video when i was 10 it got me into this hobby. Built my first bike and I love it. Now got 5 motorized bikes. You really inspired me thank you so much!
I installed a 4 stroke engine kit on my sons mountain bike. We had to modify it because the bike had hydraulic disc brakes on it but it worked great. He rode it from Malta Montana all the way to Moose lake Minnesota pulling a 2 kid carrying trailer full of camping equipment & food & he had a camping backpack he wore. It took him 9 days but he was sight seeing along the way.
I feel like he doesn’t swear working on his vehicle and stuff when something doesn’t work out smoothly. I aspire to be like him and how much effort he puts into his work
I built one of these 12 yrs ago on a tandem bike. Still runs great. 31mph on GPS via my phone. Bike weight is 87 lbs, 1 person @ 160. I use AMSoil racing 2 stroke @ 32:1 mix. 87 octane. Swapped out head studs for better and a few other tweeks. Never broke down. Let the carb run rich. Dont resize jets. If you push it like I do it likes to be rich to protect it's self.
Part Two: I got it running pretty good, the motor finally stays put. The chain tensioner made a mess of the frame and was no good from the start, so I ordered a spring-type. While it works, the spring itself requires a major upgrade in order to use it on the roads around here. Moderate bumps are okay, but one good pothole over a curve and the chain falls off. The spring isn't stiff enough, nor is it in the right place. Therefore, I'm going to take a much stiffer spring and hook it to the frame of the bike until I can get a set of motorcycle-type wheel adjusters built for a mountain bike. My recommendation is to get the motorcycle type wheel adjusters from the start and cut the chain to the right length. Tension devices are normally for things that stay put.
Bro thought I was the only one . Yea . All the smokers with bags of bottles be mobbing with this kit setup . But aye . I would too. Wel I mean I do too. Fuc it except on a super pocket bike. And without the bottles to recycle and ish.
Kobain Back in the day I put a 9HP aluminum block Briggs on a 3 speed bike. It could easily do 60MPH in 2nd gear. Never wound out 3rd. Too scared from the front wheel shaking. 😱😫😩
I've built a few of these. If you build a bicycle for the engine it's awesome if you are just trying to slap it on a random bike you'll get mixed results. Best one I have found for an engine kit is the older Schwinn Heavy Duty. They have much thicker spokes, better bearings, and beefier frame that fits the engine perfectly and the bike is a much better quality than the Walmart bike stuff you get nowadays.
Weight is your enemy when building these things tho..may I recommend starting with a high quality bike like a giant talon or a specialized hardrock/expedition
31 mph max is not bad at all!! Most non-custom ebikes get around 25 mph out of around 1000W motor. Btw that compressed air on the handles was just brilliant! I learned something new, thanks bud!
Yeah worth bearing in mind the 25mph on ebikes is probably not motor-limited but speed-limited due to legal restrictions for unlicensed motor-assisted vehicles, as well as manufacturer wanting to have a guaranteed minimum range. Even a 250W ebike can do 20mph, though it'll be slower on the acceleration. There are kits for removing motor limiters for ebikes out there, a 1000W motor should easily get you 35-40mph depending on your weight/load. But going much over 40 is just e-motorcycle territory, particularly if you're going on public roads with them.
@@InnuendoXP . Yep. I own a Trek Ebike that goes 30mph and I can ride that beauty to whatever I want to without annoying people or calling police attention
@@InnuendoXP I would agree as to why they would limit them, they do it on golf carts...lol. A 50cc gasbike weighing 72lbs is pushing it, moving a 150lb man along at 20 mph on level ground, in my experience.
This isn't true, all e-bikes sold in the US are restricted to 25mph. My bafang kit will hit 40mph easy on a mountain bike (1000W 52v), you'd probably get even better performance on a road bike. (Just FYI 40MPH is too crazy for me, I'm good around 25mph but my dad tops his out) The gas motors are junk, you'll strip the exhaust from vibrations, and you'll lose compression insanely fast. You constantly have to adjust the throttle depending on your gas level etc.
I remember going to Paris in the mid 60's, and seeing lots of people with motorized bicycles. They were fitted over the front wheel, and just connected via a roller onto the tyre.
They were made by Solex. We had them here in Quebec. There's a company putting out something similar but electric as an add on to existing bikes. If my memory serves me correctly, It's called Rubbee
My doctor suggested I start riding a bike, for my heart. This kit will be a big help. I don't know what I would have done without you. Thank you so much.
I've loved 2 stroke engines since my first Lawn Boy mower back in the 1960's. At 67 here's a chronicle of my use of 2 stroke engines. 1st model air planes 2nd lawn mowers 3rd dirt bikes 4th boat engines 5th back to lawn equipment On a side note I bought a 2 stroke Lawn Boy mower back in 1993 (now 2020) and still use it weekly in mowing season and have never had to do any thing to it except put gas in it. I love 2 strokes.
Ok so I bought one of these about a month ago and here’s what I found out. Let’s start with cons: installing, the rear sprocket was definetley the hardest part, a lot of fine tuning. It makes it a lot easier for me to take off the stock gearset so I can use another socket with an extension on the other side. Where the chain goes into the engine itself, I found I needed to grind quite a bit of material off the bottom of the enclosure to make the chain fit. That one got me for quite a while. Also, the engine likes to move to the side when the mounts aren’t torqued enough, same with the chain tensioner- I had to weld the chain tensioner to the frame, and it helps a whole lot to put two bolts on the engine mounts, along with some thread locker to avoid them coming loose. Also it helps a lot to max out both tires when you inflate it. Took me through two inner tubes that way. Last thing wrong with the kit is that the fuel shutoff valve physically came out of its enclosure and dumped fuel all over the ground. Yes I mean the actual part that you turn. I was stranded away from home on this one. Last con, the exhaust gasket material is terrible. It wore through so much it actually created a gap and the exhaust was flapping around loose. Allen bolts probably isn’t the best choice for an exhaust port... if you have the ability you should definetley replace these with studs. Now the pros: it is fast as hell, I’ll be scooping cars on uphills. And it has the same braap braap sound as a dirt bike. And it’s cheap! I definitley recommend, however, you definitely need to be mechanically inclined in order to use this kit. I had to do many fixes in the field. Overall this thing is the greatest purchase I have ever made. Too young for a drivers liscence, and this thing is way cheaper and better than any car I have seen. Oh and cold starts can be a bitch at times, let it idle to warm up before you leave.
You need this sprocket a lot easier to install and always straight www.ebay.com/i/122994823929?chn=ps&ul_ref=https%253A%252F%252Frover.ebay.com%252Frover%252F1%252F711-117182-37290-0%252F2%253Fmpre%253Dhttps%25253A%25252F%25252Fwww.ebay.com%25252Fi%25252F122994823929%25253Fchn%25253Dps%2526itemid%253D122994823929%2526targetid%253D313776935016%2526device%253Dm%2526adtype%253Dpla%2526googleloc%253D9004224%2526poi%253D%2526campaignid%253D1669934606%2526adgroupid%253D65058347459%2526rlsatarget%253Dpla-313776935016%2526abcId%253D1123856%2526merchantid%253D118857064%2526gclid%253DCjwKCAjwmq3kBRB_EiwAJkNDp2fZFB0LMw2TIMYHQu1yxm_aKEm88L3O-YphbtAmNJhBi1bsGdZNCxoCGa8QAvD_BwE%2526srcrot%253D711-117182-37290-0%2526rvr_id%253D1897253645019%2526rvr_ts%253D84fef45a1690ab1d3621fecbffcee456.

I have built two of these in the last few years my 1st one had an issue I couldn't fix but it lasted 3 years required no extra work to build it. I built my 2nd one last winter it also required no extra work to install it and have it running. Makes me think either you over thought some things or you installed on the wrong type of frame.
Got the exact same kit and it works exceptionally well. I have about 70-80 km on the engine and never had any problems. I run it on a 2% oil mix and it runs great and start real easy. Fun little thing to have.
I did a couple of these with my friends during highschool, super good fun on the mountain trails where I lived back then. Not nearly as nice as a Puch or Tomos, but a darn good bit cheaper! Cool to see you cover these!
I won two different motor bicycle kits from wish! I gave one to my 15 year old nephew and he absolutely loves it! I figured it would be a headache to build but within a week's time when I seen him next it was put together and running with no problems!
In years of experience, concerning transportation methods, I have found that the better it looks or the better it functions, the more likely it can be taken from you.
@@getoffmygrass6974 Odd, you say? In at least one state it is Still a hanging offense to steal a horse. The first roads were built to move Armies (to kill people, steal land and tax those with land). For centuries upon centuries the ability to travel was known as the life saver it is. (Just try running from a flood or fire w/o moving ~ try getting out of harm's way while staying put. Next, came taxing people during times of fleeing danger ~ (imagine a toll booth during a stampede or Ukrainians today, or Turkey or oil thers while a drought occurs...

If You live in California and can't move out... how's that going? Then imagine a government So Very Concerned it posts how sad that is while increasing gas prices. L0L. Are you backed up yet?
I just bought one of these, & the box looks exactly alike. Good timing. Using zip ties a spacers is genius. It's nice to gets tips from The Smartest Dude on UA-cam🤗✌
Just wouldn’t be “project farm” video worthy if you didn’t pull off the cylinder head and check for carbon buildup prior to testing. Outstanding-great video!!👍🏻
I bought the 80cc kit about 9 yrs ago & it was excellent. I had transport to a job which was about 15 miles from my home when I didn't own a car at the time. My biggest life hack for these set ups if it's used as vital transport (work etc) is to buy the Kevlar armoured tyres & the thorn resistant inner tubes. I rode that bike with 3 nails still stuck in the tyre for nearly 2wks (experiment) & had no issues. The tyres & tubes cost abit but they are well worth it compared to repairing punctures & maybe being late for work.
Even better are foam-filled tires, if you can find them. They do exist, but they're not very popular because they add a lot of rotating mass. That doesn't matter when you have an engine to help you move the bike, though.
But the bike is for the police like a regular bicycle or do I have to make the driving license? Edit: I have read about the laws here in Italy and you need a driving license, registration plate and to pay taxes. Italy is expensive
I work as a bike mechanic at a bike shop and someone brought one of these by. It was an absolute blast to ride. I instantly started looking up kits lol. Now I’m on the UA-cam video stage of the process. I’ll probably be building one soon lol
These things are very hit and miss. the only thing i can say for certain is if you buy one of these kits you will learn a lot about fixing small motors.
Ah man. That trick with the compressed air to remove the hand grips was great. I just replaced the grips on my wife's Schwinn and had to cut them off with box cutters! This tip is one week late! LOL!
i have one. big problem is that you need to hold the clutch in all the time if you want to pedal like a normal bike and engine off. Will tear the cluth on any eninge. Best would be if you could have something that totally separated the engine from the bike. Like a quick way of take the chain off so it wont be any resistence at all from the engine.
You should do more stuff like this. Don't get me wrong I'm a big fan of the tool testing you do when it's company vs company. This however is awesome for a whole different set of reasons.
My boys discovered that heavy-duty tubes were an absolute requirement on their rigs. They constantly blew out the tires, until they learned the difference in tube quality. Then it was "Dad we need $60 per bike for new tubes". Of course that was un-nerving, but they stopped needing new tubes all the time. And a hell of a-lot less Mother-Love to patch their knees and arms from getting hurt because of a 20 mph blow-out.
It's not stupid idiot I have a motorcycle and some times areas are closed off with gates u can put a heavy dirt bike over with a bike like this I can lift it easily over the gate and ride for miles
I've build 20 of these things literally and A few things to improve the performance on these things are to Waterproof the ignition coil with super glue or something, weld the sprocket onto the axel hub, torque the headbolts to 15 lbs of torque, and add a o-ring to where the carburetor meets the manifold. In addition the engine seems to perform better with two stock gas-tanks united by a T gas-line splitter.
Having assembled one on a Huffy frame I say they are more than worth it. I have been crusizing on mine for three years with one minor breakdown. I did have to replace a gasket on the exhaust once as well. Build one you will love it!
I have a bike kit on my bicycle since october. Only problem was the tensioner. It cost US$99. I have even done some modifications like lowering the head, made an expansion chamber, polished the exhaust and intake ports. So far, the engine is running strong!
Do you want to polish the intake? It probably doesn't make a ton of difference but I heard you want a little turbulence in there. What was wrong with the tensioner?
actually, early on when brushless electric hub motors became super small and batteries and electrical systems were fitted inside the frames, there were attempts, some even succeeded, untill it was noticed going up miles of hills and hardly sweating kinda made people wonder WTF ??? then busted, ebike kits would be FANTASTIC except for the cost of the batteries, quality kits can be very inexpensive, but in all cases, the batteries are ridiculous, $150-$200 for an average store sold bike, $200-$300 for the kits, $500-$600 for a battery that usually only has about 20 miles of life and takes 5-6 hours to charge....yah, I'm a gas motor guy for now
after watching these vids i couldn't resist. ordered a couple of these kits and got to work. The engines are great. simple cheap chinese engines. but very reliable. the chain and ancillary bits are junk. my best build to date is on a fat tire bike, i made billet brackets and a mini jack shaft on the CNC machine. Its freaking bad ass. The kid has MANY miles on this rig, it is IMHO the best modern moped going! all up cost maybe 500 bucks between the engine, bike and bits. Pro Taper makes a 415 series chain that is of SUPERIOR quality to the piece of crap that comes with the kit.
@@atmosrepair you pedal them alive so you never really notice any sort of hard starting issue. just pedal and crack the throttle till it comes to life.
@@DieselRamcharger I have been pedaling my butt off won't start, I even turned the engine over with a drill on crankshaft. I've adjusted the needle, i have compression, I can shoot flames with a lighter over spark plug hole, I have spark, might be weak cdi??? But I tried 3 different plugs too. Spark plug is usually pretty dry too which led me to try and get more fuel into it.
@@atmosrepair in my experience these things come jetted extremely rich. i would take the carb off and put an o ring inside of it so when you push it onto the intake snout it has something to seal against. i do this to all my bike engines before i ever try to start them. When you pedal hold the throttle wide open till it starts to spit and sputter. everything is very cheap. there can be fuel supply issues from the tank, the petcock, the fuel line and filter and the carb itself. you just sort of have to check everything. pull the spark plug and squirt some premix in there. it should fire right up. if not, its a weak spark issue.
The fact that you spend all this money from you own pocket and are super honest with the testing for each product you are so helpful and have saved me quite a bit of money and time all i can say is thank you and keep on my freind
I think the flying horse are the good bike motors maybe, i have heard the cheaper one may vibrate apart, your favorite thread lock may come in handy... And a better tensioner....But great fun for the price!
You did an excellent job putting that kit together on your bike. I had a little 49cc bike when I was younger. I took it apart and reported the head. It got twice the horsepower. I was really happy with it. If you polish up or down in the opening, it will change the timing. But side ways is good and that was how it gained the power. I watch all of your videos. Even if I don’t have the tool. I still find them interesting. Later
Where I can find the double 2-stroke engine and for my beach cruiser GT me and my father just put custom made spring front and disc brake and lights set for one thing I'm missing engine an awesome video
you just showed how what we in india call a moped is made. my sis and i shared something called luna. it was brilliant. i have climbed steep mountain roads with it. they are quite capable and fun. although back then my maintenance skills were limited to keeping the rims shining. thanks for making this video. thoroughly enjoyed it.
I Used to ride one of these around for years back in 2013. 35mph with a 2 stroke exhaust. I hooked up a buggy for to the bag and that's how I did my grocery and Christmas shopping. Fell once in the snow but it's all part of the fun
Mines been going for over 5 yrs and still running.i live 26 miles where i ride it too so i do 52 miles round trip every tues and sat...Btw its on a 29 inch mount bike..48cc 2 stroke
ua-cam.com/video/qlEzRS9KrPc/v-deo.html watch till the end lol i get dusted i know its shaky but its hard to ride and hold a cam still that me on it and it dies from the oil sensor i disable it so now i can do donuts without it dying
The tip about on removing handle grips is a good one! Helped a friend install one of these kits on a bike years ago, funny to see the kit itself really hasn't changed much at all.
those kits haven't changed in almost 50 years, lol. the only real difference is who makes them. a similar system called the "whizzer" dates back to the 30s here in the US, but is quite a bit more refined. i've heard the "chineseum" modern variety is basically a clone of a russian product of the 50s, which has been copied and sold almost everywhere, by almost everybody, at one time or another. the origins of the honda motorcycle company go back to a similar product in the post ww2 era, btw.
I have one of these and love it :) It was a challenge getting the chain and sprocket aligned perfectly, and the tensioner is a pos lol. But all and all worth the +$100. I had to get the 50cc version in order to not require insurance
Now to install one of those cheap $20 nitrous kits..... Great video, I really wanted to see you riding the kit on camera, not just the drone footage. See how it performs from a standing start etc. It didn't seem to smoke that much on the ride. Check out 2strokestuffing. He has a similar kit and has adjusted port timing, compression and will shortly be adding an expansion chamber & decent carb... he also has a home made dyno and has dynod every change he has made for ultimate nerding out!
I bought the same kit on ebay for $85. I didn't have a bike so I bought one from Walmart. Install was fun because I like customizing things to make them fit. Wasn't a fan of the sprocket set up so I drilled out the center and used the brake rotor mounting screws. That was a waste of time because it didn't line up with the motor. So I used the sketchy two piece rubber sandwich and it worked OK. I didn't have the optional front mount so I built one and it's remarkably similar to the one in your kit. I used a u bolt but put clear vinyl tubing on the ubolt so it wouldn't scratch the frame. Starting it was a problem because you have to choke it, have the kill switch off, and the gas on. The gas was easy to figure out. The choke took some playing with and I used a multimeter to figure out which way killed the engine, and which way allowed it to run. It also took a bit to get the gas to the motor. After figuring out how to start it I took it for a few test rips and quickly discovered that it was very dangerous to try and stop it. When squeezing the break lever it caused the twist grip to rotate. I solved that by replacing the twist grip throttle to a thumb push throttle. I also had an issue with the bike being dual disc brakes. The rear break interfered with the chain and sprocket. You need a rear brake. So I robbed the rear cantilever rim brake from one of the kids 20" bikes and there was already the same mounting points on the mountain bike so it all bolted right up. I then had a few problems throwing the chain occasionally. I tried the chain on top, and the chain below the tensioner. But I ended up with a spring loaded tensioner that bolted to the engine case. Next problem was after riding it around town my rear end was beat to death because there's no rear suspension. So I bought a big cushy seat that helped a little bit. Then I found a suspension seat post. It has an internal spring in the post. That solved the sore rear end problem. Now the bike is a lot of fun to ride and everybody rides it all over town. It moves out pretty good
What helps the most is removing chain tensioner and making the chian right without it .... I made a adjustment bolt and nut to move motor in or away from frame .. takes very little movement to move half a link and if its tight its right not to tight tho
Cody Felix Rubber engine mounts are literally called isolation dampeners. They help prevent vibration from the engine being transferred to the frame. All cars have them and most motorcycles as well.
they have them but ubolting the muffler to the frame does help allot you don't want any play in the motor at all because if the motor can move side to side even a few mm the bad vibes only increase x10
That seems like really good value for money mate. How much extra weight was added to the bike? Can you build a 4 stroke one for comparison? Keep up the good work. Cheers Mick from Aussie👌🤝
Back in the day, they had "Aqua-Bug" kits that were a COMPLETE motor and drive assembly that would mount on the front, used friction drive to drive the front wheel. Could be mounted in half-hour, if I remember correctly, they cost about $100.
I had one called Bike Bug. Friction drive rubber roller on the front tire. Good for yuks, but I never did like the idea of additional wear on the tire.
I watched this years ago and decided to try it… as long as the engine is bought from a good retailer and you disassemble it and reassemble and check everything.. so far its been reliable
The shake might not be because of the engine. My bike shakes like that if I get it above 25mph (which usually only happens on big hills). The cheap (under $500) mountain bikes just aren't built for speed
At higher speeds, it definitely IS the engine. These cheap Chinese two-strokes vibrate like hell above 5000 RPM. But if your bike is vibrating above 25 MPH, I would check the wheel balance. Bicycle wheels are not normally balanced. But if you are racing your bike, you need to balance your wheels: both statically and dynamically. One caveat: once you pick up a pebble on the road, it'll cause a minor vibration. AAAAAAAAhhhhh, the JOYS of bicycle racing!
Just a thought. Next time when installing a new gas tank it’s a good idea to add a little fuel to it and slosh it around a few times and drain it. When a kit doesn’t cost much they skip the cleaning step because it saves a few pennies.
this is ABSOLUTELY true !!!, thank you, I often give advice for people wanting/getting a motor and I give pretty detailed advice usually, but I never thought to add that little bit, Delaney, thank you for reminding me :)
hahaha speaking of cleaning out these cheap kits, people have found newspaper in the crank case. Definitely worth it to take an hour tearing it down before installing
garrett smith of course but only for a minute or two if that lol because as u know a two stroke has oil in the gas which goes through the top. End to lubricat it
FYI the needle bearing of a elite50 Honda scooter from the 80s fits where the piston goes to the crank arm also some of them can be bushings which don’t do well on high rpms
Thanks for not lying about this kit and it's abilities or downplaying the actual ability and purpose of the engine it's great and you had a pretty good video
i reckon they're great, that one is no where near as good as the high performance model of it which is only $40 more and for that extra price you get a ton more quality, power and speed, however after using these engines to get from school and back for 3 years i copped a $2000 fine for riding an unregistered 'motorbike' with no license on a footpath next to a road, so thats the other side of it, so look into the laws in your country before buying said kit, its pretty rough copping a fine that big, espcially if you dont have a job, and after the amount of time spent making and fixing the bike, you get pretty attached, i ended up spending a total of about $500 (minus fuel) buying a custom bike, upgrading to the high performance engine, managed to sell it for half of that, but apart from all that it was a brilliant bike!
I don't buy the fine either. In the US anyway, under 50CC doesn't need registered. Riding on a walking path will get you in trouble, but not $2000 trouble.
@@brendanberry7403 i promise you i got the fine haha, im in australia, was riding an 80cc 2 stroke, got fined for riding on the sidewalk next to a road which counts as being on the road apparantly, for riding an unregistered, unsafe vehicle, im unlicensed which is relevant because i was next to the road, and i didnt have a helmet on. the fine came as quite a shock because i'd talked to multiple cops about it before and they just thought that "it was cool" or " i wish i had one when i was younger" but then one day around when australia was pretty much on fire i flew past a cop, doing about 40-60kph, was my fault, i shoulda worn a helmet and been more cautious

You may be interested in 2-stroke Stuffing's videos. He's tested a lot of mods and upgrades on his bike on a dyno., Evidently the best mod is just removing the baffle or complete end cap from the exhaust. Anyway, most go 35 straight out of the box after the break-in period. Personally the best upgrades you can do for the money would be the chain($22 gets you 10ft of #41 chain from Tractor Supply which makes 2 chains that are exponentially stronger than the original) and an engine mounted spring chain tensioner (can be bought for $20 shipped if you shop around on eBay) which is so much better than the stock one that constantly shifts, and sometimes is even shoved right into the spokes of the rear wheel while moving. For reliability and safety I'd call these two things imperative.
Monkey J thanks for bringing the tensioner into the spokes situation up. I just checked mine and the bolt shank is clearing by 1/4". Securing the tensioner from rotating on the fork leg to keep it out of the spokes is imperative.
Most states require a motorized vehicle to be registered if used on the road, not sure about drivers license. I'll stick with my motorcycles! But thanks for the education I've learned a lot from watching your videos!
Great build, and it’s videos like these that keep my son interested in your content. As much as I love the penetrating oil tests, it’s not as exciting for a 14 year old. Thanks again from a happy, long time subscriber! Happy New Year!
because of how 2 stroke engines use the fuel/oil mix to lube, much of it burns off but still leaves some residue, most oil additives are designed for 4 stroke motors, using oil additives in 2 strokes can not only REDUCE the efficiency of the fuel burning off, but the residues themselves actually increase the need for regular maintenance more frequently and CAUSE long term damage and reduction of engine life, and believe it or not, using full or blend synthetic oils in the fuel/oil also REDUCE fuel efficiency because of the higher resistance to high heat and ignition, a strait up proprietary, pure 2-stroke oil and shell premium with nitrogen is best. also, do not use fuel additives that add octane, on small 2 stroke engines they serve no purpose, the compression is not sufficient enough to be of any benefit. DO NOT use fuel additives that have lots of detergents, except when doing breakdown maintenance, the engine relies heavily on the oil residue to lubricate and detergent additives in oils break down that function causing increased wear and tear, increasing the frequency of maintenance and reducing engine life. if you insist on using a supplemented oil (an oil with additives) or oil additives anyway, NEVER, EVER, EVER use ones that have or add metallic and/or flammable substances such as zinc and phosphorus, these are optimized for 4 stroke engines, because 2 stoke engines burn off the oils, the metallic additives create deposits that actually damage the piston walls and rings, further increasing the need for breakdown maintenance and reducing engine life, as for flammable additives such as phosphorus and sulphates, these burning off in the engine create acids and cause severe corrosion in these smaller engines especially. keep your oils and fuels as pure as possible and it will help greatly when you intend on storing your bike for more than 60 days, empty the fuel tank and add a fuel stabilizer but NO oil, when you decide to go and ride again, add the requisite amount of oil, then idle the engine for 10 minutes, shut down for 30-45+ minutes for cool down, then go and have fun try and remember, "2 stroke" & "4 stroke" are NOT numbers, they are completely different types of engines, and need to be treated as such. I do recommend an oil additive called 'nanolub csx', but NOT for mixing in the fuel, it makes an AWSOME lubricant for external moving parts on the engine and bicycle and chain, may your bikes "Live Long & Prosper"
addendum to the storage tips: when you empty the tank, do fill up the tank halfway with fresh premium fuel (unmixed) then add the stabilizer, when preparing to restart, then fill the tank with premium and add your oil
I agree with you, but please learn how to use punctuation properly. Your entire post is strung together with commas, which makes it hard to tell where one thought ends and the next begins.
What's negative to say? I bought a kit on eBay for $69 shipped to my door in three days. Hell, the guy was even nice enough to refund half the cost of a new better chain when the original one kept falling apart. Couple that kit with a nice inexpensive fixer upper and $60 in upgrades and you've got a fairly reliable mode of transportation that is much more fun than simply pedaling around town, and a whole lot easier around here. I mean where else can you find a sub $200 vehicle that needs $9 registration, no inspection, and gets 75-150mpg when gas is nearing $3 again? I don't see what there is to not like honestly, or what you could even get inflated expectations over. I mean if you expect a proper motorcycle buy a proper motorcycle (which is admittedly what some people should do, considering they spend $1000+ on what is in the end just a bike with a motor no matter how you look at it), but in the intended form, which as far as I'm concerned is an inexpensive mode of transportation, they do precisely what they're designed to do and do it at a price point pretty much nothing else can other than maybe one of those little battery powered RAZR scooters -_-
I bought the bike engine kit on wish.com but it took a month or so to arrive. Here's a like to one I found on Amazon: 2 stroke bike kit: amzn.to/31i5M6W

4th year after trusting your review and buying one of those kits here. It still runs flawlessly after a lot of abuse and neglect both in trail and regular commute. The only thing that failed after first year was the stock chain, stretching up to the point of sagging (replaced with garage door chain, which only stretched by 1 link in 3rd year so far). This thing really changed my life becoming my main way of mid-long range transport (Especially great for hauling bags of potatoes when 2 large milk and bread crates are installed. My heart would probably give up on regular bike if I tried to move all of that around). Thanks.

My grandfather from NJ got me involved in motorized bicycle kits. He had a 2-stroke that sat on the front of the 10-speed and used friction against the tire to run the bike. I would always ride this contraption when I would visit him as a kid. I was enthralled.
A few years later I saved enough grass cutting and snow shoveling money to buy a kit that Sears had. The kit used the same method of drive and after a few years and many friction wheels replaced I graduated to a moped and finally motorcycles. Good memories. Thanks for making this video. 😉
You are welcome! Thanks for sharing.
I had that same Sears kit you are talking about in about 1984. My dad got it for me, it was awesome when I was like 13.
When I was a kid, I lived in Iran (1958-1960) and I saw quite a few bicycles puttering about with 2 stroke motors affixed to the handlebars. Everything there is very much spread out, and hot, and dry. You could get heat stroke pedaling from village to village (I lived in a little port town called Abidan) but the guys I saw riding these contraptions looked quite pleased with themselves.

Hey Todd! To minimize the engine vibration, get an old tire and cut it into strips. Use the strips between the engine and the frame to prevent engine vibrations from being transferred to the frame. Anything rigid connecting the engine to the frame (chain guard, muffler, etc) should be isolated from the frame as well. Thanks for your service!
Thanks for the feedback.

Old biker trick .
@@ProjectFarmI bought the 100cc one hope it goes 50+ mph
Some pointers for people who're interested in using one of these based on my experience of about 2000 miles:
I built a bike with a 49cc varient of this engine back in 2011 and used it for going to college. I used a steel frame to avoid the metal fatigue the vibrations would cause to some aluminium frames making them weaker. Even painted it and did a 100% custom job, she was a lovely yoke to potter around on here in Ireland.
-The slang term on the internet for this specific engine is called a "happy time engine" because very few of them last beyond 2500 to 3500 miles due to poor quality components.
-Heavier bike frames are more suitable and lighter ones(i.e. racing bikes) have less material to support these.
-Disc brakes on at least the front are really mandatory because in the rain standard bicycle brakes will seem absolutely terrifying, trust me on that. I installed a 180mm hydraulic disc brake on the front personally.
-Replace the chinese spark plug straight away, they suck.
-The original spark plug caps are also terrible, I bought an NGK one for 5 euro in a motorbike shop.
-I ran 25:1 after the break in and accepted spark plug cleaning duties to increase engine life.
-The front left engine cover is highly prone to water ingress and in light rain was caused the electrical system to fail on me twice meaning I've had to replace the stator. If I was building another one I'd drill a hole on the bottom of that compartment for drainage and seal up the rest of it even better than I already did.
-The clutch arm actuates a pin inside the engines sprocket that relies on that sprocket cover being on very tight. The pin and arm are made of very poor quality steel and it's a completely dry metal to metal contact so I highly advise regualr grasing of it and carrying some kind of screwdriver to tighten the cover if it gets loose or you'll be pedeling a very heavy bicycle home very slowly.
-The exhausts and their bolts can rust very quickly if not looked after.
-The petol tanks 4 studs are low quality and directly welded to the tank so they strip easiliy.
-Bring a small pre measured bottle of 2 stroke oil with you so you can just dump it into the petrol tank when empty and fill up at any petrol station.
-Ensure the carb screws are set correctly.
-Do not use off road tyres on paved roads. I had a small accident because extra weight + low traction + slight leaning = bad time.
-Hgher tyre pressures than normal are required for the excess weight.
I stopped using mine in Ireland in 2012 as the laws were changed and the motorized bicycle then fell into the category of a moped even though it was under 50cc. Fail to follow tthe laws where you live at your own peril.
If any of you guys have any questions that I haven't answered already I don't mind.
These are great tips--thank you!
I own a motorized bicycle repair shop and i agree with everything this dude say
If you install a front disc brake, you need a fork that will support it: standard forks will bend from the force put on the caliper. If you don't mind building a wheel, a drum brake is a good alternative.
kingedwin poop or dont ride in the rain is an even better alternative. Stay dry
I don't plan to ever do this, but reading your pointers was super interesting
By watching this video when i was 10 it got me into this hobby. Built my first bike and I love it. Now got 5 motorized bikes. You really inspired me thank you so much!

Part Two: I got it running pretty good, the motor finally stays put. The chain tensioner made a mess of the frame and was no good from the start, so I ordered a spring-type. While it works, the spring itself requires a major upgrade in order to use it on the roads around here. Moderate bumps are okay, but one good pothole over a curve and the chain falls off. The spring isn't stiff enough, nor is it in the right place. Therefore, I'm going to take a much stiffer spring and hook it to the frame of the bike until I can get a set of motorcycle-type wheel adjusters built for a mountain bike. My recommendation is to get the motorcycle type wheel adjusters from the start and cut the chain to the right length. Tension devices are normally for things that stay put.
Thanks for the update! Glad it's working out for you! They are a lot of fun.

31 mph max is not bad at all!! Most non-custom ebikes get around 25 mph out of around 1000W motor. Btw that compressed air on the handles was just brilliant! I learned something new, thanks bud!
Thanks for the feedback.
Yeah worth bearing in mind the 25mph on ebikes is probably not motor-limited but speed-limited due to legal restrictions for unlicensed motor-assisted vehicles, as well as manufacturer wanting to have a guaranteed minimum range. Even a 250W ebike can do 20mph, though it'll be slower on the acceleration. There are kits for removing motor limiters for ebikes out there, a 1000W motor should easily get you 35-40mph depending on your weight/load.
But going much over 40 is just e-motorcycle territory, particularly if you're going on public roads with them.
@@InnuendoXP . Yep. I own a Trek Ebike that goes 30mph and I can ride that beauty to whatever I want to without annoying people or calling police attention
@@InnuendoXP I would agree as to why they would limit them, they do it on golf carts...lol. A 50cc gasbike weighing 72lbs is pushing it, moving a 150lb man along at 20 mph on level ground, in my experience.
This isn't true, all e-bikes sold in the US are restricted to 25mph. My bafang kit will hit 40mph easy on a mountain bike (1000W 52v), you'd probably get even better performance on a road bike.
(Just FYI 40MPH is too crazy for me, I'm good around 25mph but my dad tops his out)
The gas motors are junk, you'll strip the exhaust from vibrations, and you'll lose compression insanely fast. You constantly have to adjust the throttle depending on your gas level etc.
I remember going to Paris in the mid 60's, and seeing lots of people with motorized
bicycles. They were fitted over the front wheel, and just connected via a roller onto
the tyre.
Interesting. Friction drive systems are still sold
That's the Velo Solex, those a great fun, they are not converted bicycles, they where actually build from the factory that way

Ok so I bought one of these about a month ago and here’s what I found out.
Let’s start with cons: installing, the rear sprocket was definetley the hardest part, a lot of fine tuning. It makes it a lot easier for me to take off the stock gearset so I can use another socket with an extension on the other side. Where the chain goes into the engine itself, I found I needed to grind quite a bit of material off the bottom of the enclosure to make the chain fit. That one got me for quite a while. Also, the engine likes to move to the side when the mounts aren’t torqued enough, same with the chain tensioner- I had to weld the chain tensioner to the frame, and it helps a whole lot to put two bolts on the engine mounts, along with some thread locker to avoid them coming loose. Also it helps a lot to max out both tires when you inflate it. Took me through two inner tubes that way. Last thing wrong with the kit is that the fuel shutoff valve physically came out of its enclosure and dumped fuel all over the ground. Yes I mean the actual part that you turn. I was stranded away from home on this one. Last con, the exhaust gasket material is terrible. It wore through so much it actually created a gap and the exhaust was flapping around loose. Allen bolts probably isn’t the best choice for an exhaust port... if you have the ability you should definetley replace these with studs.
Now the pros: it is fast as hell, I’ll be scooping cars on uphills. And it has the same braap braap sound as a dirt bike. And it’s cheap! I definitley recommend, however, you definitely need to be mechanically inclined in order to use this kit. I had to do many fixes in the field.
Overall this thing is the greatest purchase I have ever made. Too young for a drivers liscence, and this thing is way cheaper and better than any car I have seen.
Oh and cold starts can be a bitch at times, let it idle to warm up before you leave.
Awesome! They need a lot of TLC but are a lot of fun. Please be safe!
Great real world info. Thanks.

I have built two of these in the last few years my 1st one had an issue I couldn't fix but it lasted 3 years required no extra work to build it. I built my 2nd one last winter it also required no extra work to install it and have it running. Makes me think either you over thought some things or you installed on the wrong type of frame.
As a 2 stroke bicycle owner, I can confirm this is all true. Especially that last part.
Got the exact same kit and it works exceptionally well. I have about 70-80 km on the engine and never had any problems. I run it on a 2% oil mix and it runs great and start real easy. Fun little thing to have.
Thanks for sharing!
Compressed air on the handles, genius!
Thanks!
If you work on bikes you know about the compressed air method
Pressure washer also works on it
@@hubertkam7647 no just use alcohol under the grips
@@hubertkam7647 water works too
I’m glad you covered this topic. I’ve wondered about these kits for years.
I really like the kit! It's a lot faster way to get places then pedaling!
I did a couple of these with my friends during highschool, super good fun on the mountain trails where I lived back then.
Not nearly as nice as a Puch or Tomos, but a darn good bit cheaper! Cool to see you cover these!
I own it, its from bike berry, good stuff but no costumer service
I won two different motor bicycle kits from wish! I gave one to my 15 year old nephew and he absolutely loves it! I figured it would be a headache to build but within a week's time when I seen him next it was put together and running with no problems!

Kind of an odd outlook on life, must suck thinking that way.
@@getoffmygrass6974 Odd, you say? In at least one state it is Still a hanging offense to steal a horse. The first roads were built to move Armies (to kill people, steal land and tax those with land). For centuries upon centuries the ability to travel was known as the life saver it is. (Just try running from a flood or fire w/o moving ~ try getting out of harm's way while staying put. Next, came taxing people during times of fleeing danger ~ (imagine a toll booth during a stampede or Ukrainians today, or Turkey or oil thers while a drought occurs...

I just bought one of these, & the box looks exactly alike. Good timing. Using zip ties a spacers is genius. It's nice to gets tips from The Smartest Dude on UA-cam🤗✌
Thank you for the positive feedback and hope you enjoy the bike kit!

Just wouldn’t be “project farm” video worthy if you didn’t pull off the cylinder head and check for carbon buildup prior to testing.
Outstanding-great video!!👍🏻
Thank you!
If it was a new kit there wouldn't be any carbon. It would be clean as a whistle
@@reallee5331 That doesn't matter. IT MUST BE CHECKED!
@@reallee5331 well you never know, lol 😂
He had to smear some bacon grease in it for break in.
I bought the 80cc kit about 9 yrs ago & it was excellent. I had transport to a job which was about 15 miles from my home when I didn't own a car at the time. My biggest life hack for these set ups if it's used as vital transport (work etc) is to buy the Kevlar armoured tyres & the thorn resistant inner tubes. I rode that bike with 3 nails still stuck in the tyre for nearly 2wks (experiment) & had no issues. The tyres & tubes cost abit but they are well worth it compared to repairing punctures & maybe being late for work.
Great hack!
ScottyFox tires
Even better are foam-filled tires, if you can find them. They do exist, but they're not very popular because they add a lot of rotating mass. That doesn't matter when you have an engine to help you move the bike, though.
But the bike is for the police like a regular bicycle or do I have to make the driving license?
Edit: I have read about the laws here in Italy and you need a driving license, registration plate and to pay taxes. Italy is expensive
ScottyFox can you post a link to where I can buy the 80cc kit you have please?
I work as a bike mechanic at a bike shop and someone brought one of these by. It was an absolute blast to ride. I instantly started looking up kits lol. Now I’m on the UA-cam video stage of the process. I’ll probably be building one soon lol
Thanks for sharing!
These things are very hit and miss. the only thing i can say for certain is if you buy one of these kits you will learn a lot about fixing small motors.
@Eric Matson how many miles would you get outta one
You do more fixing than anything
Nameranthgin You're forced to learn about the machine you're operating and you consider that a problem? 🙄 You really shouldn't be using machines.
Ah man. That trick with the compressed air to remove the hand grips was great. I just replaced the grips on my wife's Schwinn and had to cut them off with box cutters! This tip is one week late! LOL!
Helps if you have a one of the dust blower attachments that has a small tube on it, you can flatten it and get under grips really easily.
RixCanDoit
It works great for putting new grips on too! 😊
I used window cleaner and a mallet. LOL!
When it's time to slide on new rubber grips, grab your wife's hairspray. Seriously.
Thank you!
Worth it just for the trick to remove grips with compressed air. Those things can be stubborn!
Thank you!
Yea, he made it look so easy XD Nice to know about that
I use a wrench and a hammer and just tap it off.
or steal the missus' hairspray. works in reverse too & "glues" them in place.
i have one. big problem is that you need to hold the clutch in all the time if you want to pedal like a normal bike and engine off. Will tear the cluth on any eninge.
Best would be if you could have something that totally separated the engine from the bike. Like a quick way of take the chain off so it wont be any resistence at all from the engine.
You should do more stuff like this. Don't get me wrong I'm a big fan of the tool testing you do when it's company vs company. This however is awesome for a whole different set of reasons.
Yes, this was really fun to watch.
My boys discovered that heavy-duty tubes were an absolute requirement on their rigs. They constantly blew out the tires, until they learned the difference in tube quality. Then it was "Dad we need $60 per bike for new tubes".
Of course that was un-nerving, but they stopped needing new tubes all the time. And a hell of a-lot less Mother-Love to patch their knees and arms from getting hurt because of a 20 mph blow-out.
Great point!
Sapphire Sword talcum powder a good use
This device is completely stupid, and I kind of love it. You should do a series on it for making it faster/better.
LOL! Great recommendation on doing mods.
Jase Poag
faster? You want to see it go faster? Tell the meth user riding it that the Dealer's closing in 5 minutes you'll see that thing fly
FSEVENMAN lol
FSEVENMAN meth dealers never close
It's not stupid idiot I have a motorcycle and some times areas are closed off with gates u can put a heavy dirt bike over with a bike like this I can lift it easily over the gate and ride for miles
I've build 20 of these things literally and A few things to improve the performance on these things are to Waterproof the ignition coil with super glue or something, weld the sprocket onto the axel hub, torque the headbolts to 15 lbs of torque, and add a o-ring to where the carburetor meets the manifold. In addition the engine seems to perform better with two stock gas-tanks united by a T gas-line splitter.
Thanks for sharing.
@@ProjectFarm Sounds like a easy video idea if you still got it lying around. ;)
Hope you get ran over, arrested or both.
Do any companies sell them already built with a bigger motor?
@@intensivemanagement They are not hard to build. But you could get a mechanic shop to assemble it for you.
Having assembled one on a Huffy frame I say they are more than worth it. I have been crusizing on mine for three years with one minor breakdown. I did have to replace a gasket on the exhaust once as well. Build one you will love it!
Thanks for the feedback.
I have a bike kit on my bicycle since october. Only problem was the tensioner. It cost US$99. I have even done some modifications like lowering the head, made an expansion chamber, polished the exhaust and intake ports. So far, the engine is running strong!
Impressive mods!
Do you want to polish the intake? It probably doesn't make a ton of difference but I heard you want a little turbulence in there. What was wrong with the tensioner?
williwonti it would get loose and get into the wheel spokes.
williwonti there is turbulence, but polishing it makes it less of a problem
Did you lower the head to up compression? What did you use?
next step tour de France no-one will notice
lol!
VPPAF hahahaha nice plan other cyclist will do the same.
VPPAF For the 1st time it will be the bike on steroids. Lol.
VPPAF easier than changing all or your blood
actually, early on when brushless electric hub motors became super small and batteries and electrical systems were fitted inside the frames, there were attempts, some even succeeded, untill it was noticed going up miles of hills and hardly sweating kinda made people wonder WTF ??? then busted, ebike kits would be FANTASTIC except for the cost of the batteries, quality kits can be very inexpensive, but in all cases, the batteries are ridiculous, $150-$200 for an average store sold bike, $200-$300 for the kits, $500-$600 for a battery that usually only has about 20 miles of life and takes 5-6 hours to charge....yah, I'm a gas motor guy for now
after watching these vids i couldn't resist. ordered a couple of these kits and got to work. The engines are great. simple cheap chinese engines. but very reliable. the chain and ancillary bits are junk. my best build to date is on a fat tire bike, i made billet brackets and a mini jack shaft on the CNC machine. Its freaking bad ass. The kid has MANY miles on this rig, it is IMHO the best modern moped going! all up cost maybe 500 bucks between the engine, bike and bits. Pro Taper makes a 415 series chain that is of SUPERIOR quality to the piece of crap that comes with the kit.
Great information. Thank you
Is it hard to get it started on the first crack? I have it all put together but havent started yet
@@atmosrepair you pedal them alive so you never really notice any sort of hard starting issue. just pedal and crack the throttle till it comes to life.
@@DieselRamcharger I have been pedaling my butt off won't start, I even turned the engine over with a drill on crankshaft. I've adjusted the needle, i have compression, I can shoot flames with a lighter over spark plug hole, I have spark, might be weak cdi??? But I tried 3 different plugs too. Spark plug is usually pretty dry too which led me to try and get more fuel into it.
@@atmosrepair in my experience these things come jetted extremely rich. i would take the carb off and put an o ring inside of it so when you push it onto the intake snout it has something to seal against. i do this to all my bike engines before i ever try to start them. When you pedal hold the throttle wide open till it starts to spit and sputter. everything is very cheap. there can be fuel supply issues from the tank, the petcock, the fuel line and filter and the carb itself. you just sort of have to check everything. pull the spark plug and squirt some premix in there. it should fire right up. if not, its a weak spark issue.
The fact that you spend all this money from you own pocket and are super honest with the testing for each product you are so helpful and have saved me quite a bit of money and time all i can say is thank you and keep on my freind
Thank you!

I was just wondering this myself. Doesn't say much for the UA-cam ecosystem, but at least he's not getting cancelled. Yet.
You did an excellent job putting that kit together on your bike. I had a little 49cc bike when I was younger. I took it apart and reported the head. It got twice the horsepower. I was really happy with it. If you polish up or down in the opening, it will change the timing. But side ways is good and that was how it gained the power. I watch all of your videos. Even if I don’t have the tool. I still find them interesting. Later
Thanks! Thanks for watching!
We used.JB Weld to make the exhaust port higher to hold compression longer. It worked.
My friend had one, he didn’t know how to work a clutch, was funny watching him ride that thing around town.
Thats awesome. Lol I watch this guy at 7eleven every morning on one of these. He just zips by. Haha
Thinking of getting one myself. 😄

those kits haven't changed in almost 50 years, lol. the only real difference is who makes them. a similar system called the "whizzer" dates back to the 30s here in the US, but is quite a bit more refined. i've heard the "chineseum" modern variety is basically a clone of a russian product of the 50s, which has been copied and sold almost everywhere, by almost everybody, at one time or another. the origins of the honda motorcycle company go back to a similar product in the post ww2 era, btw.
Might be cool to see a competition between a two-stroke bike kit a 4-stroke bike kit and electric bike kit
Thanks for the suggestion.
Sweet 2nd vid in one week! What a treat
Thank you!
I have one of these and love it :) It was a challenge getting the chain and sprocket aligned perfectly, and the tensioner is a pos lol. But all and all worth the +$100. I had to get the 50cc version in order to not require insurance
I really like these little kits too! They are a lot of fun.
Oh i have an 80cc for a stingray bike
PETA how fast does your bike go? and what motor do you use. bc i got a stingray i’m boutta but a motor on too

Now to install one of those cheap $20 nitrous kits.....
Great video, I really wanted to see you riding the kit on camera, not just the drone footage. See how it performs from a standing start etc. It didn't seem to smoke that much on the ride. Check out 2strokestuffing. He has a similar kit and has adjusted port timing, compression and will shortly be adding an expansion chamber & decent carb... he also has a home made dyno and has dynod every change he has made for ultimate nerding out!
Where can I find a $20 nitrous kit? Could you send the link to me at projectfarm52@gmail.com Thank you!
Project Farm - its $35 but you get the idea! Ps I have never used this company before!

This is a great idea
This needs to happen on one of the lawnmowers!
Holy shit. What if you made a car using cheap crappy kits.
I bought the same kit on ebay for $85. I didn't have a bike so I bought one from Walmart. Install was fun because I like customizing things to make them fit. Wasn't a fan of the sprocket set up so I drilled out the center and used the brake rotor mounting screws. That was a waste of time because it didn't line up with the motor. So I used the sketchy two piece rubber sandwich and it worked OK. I didn't have the optional front mount so I built one and it's remarkably similar to the one in your kit. I used a u bolt but put clear vinyl tubing on the ubolt so it wouldn't scratch the frame. Starting it was a problem because you have to choke it, have the kill switch off, and the gas on. The gas was easy to figure out. The choke took some playing with and I used a multimeter to figure out which way killed the engine, and which way allowed it to run. It also took a bit to get the gas to the motor. After figuring out how to start it I took it for a few test rips and quickly discovered that it was very dangerous to try and stop it. When squeezing the break lever it caused the twist grip to rotate. I solved that by replacing the twist grip throttle to a thumb push throttle. I also had an issue with the bike being dual disc brakes. The rear break interfered with the chain and sprocket. You need a rear brake. So I robbed the rear cantilever rim brake from one of the kids 20" bikes and there was already the same mounting points on the mountain bike so it all bolted right up.
I then had a few problems throwing the chain occasionally. I tried the chain on top, and the chain below the tensioner. But I ended up with a spring loaded tensioner that bolted to the engine case.
Next problem was after riding it around town my rear end was beat to death because there's no rear suspension. So I bought a big cushy seat that helped a little bit. Then I found a suspension seat post. It has an internal spring in the post. That solved the sore rear end problem. Now the bike is a lot of fun to ride and everybody rides it all over town. It moves out pretty good
Thanks for sharing.
If you could build some rubber engine isolation mounts, it would probably make a huge difference on the vibration.
Great tip!
What helps the most is removing chain tensioner and making the chian right without it .... I made a adjustment bolt and nut to move motor in or away from frame .. takes very little movement to move half a link and if its tight its right not to tight tho
nope. it needs to be a solid mount. rubber actually adds to vibrations.
Cody Felix Rubber engine mounts are literally called isolation dampeners. They help prevent vibration from the engine being transferred to the frame. All cars have them and most motorcycles as well.
they have them but ubolting the muffler to the frame does help allot you don't want any play in the motor at all because if the motor can move side to side even a few mm the bad vibes only increase x10
That seems like really good value for money mate. How much extra weight was added to the bike? Can you build a 4 stroke one for comparison? Keep up the good work. Cheers Mick from Aussie👌🤝
Here's the 4 stroke build and it works very well too. ua-cam.com/video/CJV4TkxSfNA/v-deo.html
MOTOR ADDS ANOTHER MAYBE 30 POUNDS TO BIKE
Back in the day, they had "Aqua-Bug" kits that were a COMPLETE motor and drive assembly that would mount on the front, used friction drive to drive the front wheel. Could be mounted in half-hour, if I remember correctly, they cost about $100.
Thanks for the feedback.
I had one called Bike Bug. Friction drive rubber roller on the front tire.
Good for yuks, but I never did like the idea of additional wear on the tire.
I watched this years ago and decided to try it… as long as the engine is bought from a good retailer and you disassemble it and reassemble and check everything.. so far its been reliable
Thanks for the feedback.
The shake might not be because of the engine. My bike shakes like that if I get it above 25mph (which usually only happens on big hills). The cheap (under $500) mountain bikes just aren't built for speed
Great point.
At higher speeds, it definitely IS the engine. These cheap Chinese two-strokes vibrate like hell above 5000 RPM.
But if your bike is vibrating above 25 MPH, I would check the wheel balance. Bicycle wheels are not normally balanced. But if you are racing your bike, you need to balance your wheels: both statically and dynamically. One caveat: once you pick up a pebble on the road, it'll cause a minor vibration. AAAAAAAAhhhhh, the JOYS of bicycle racing!
Green Slime tire sealer acts as a liquid tire balance
My gasbike shakes like hell at 30mph but its got bad ball bearings and the motor doesnt help lol
Last time I used green slime (and following the instructions), it threw off my tire's balance.
Just a thought.
Next time when installing a new gas tank it’s a good idea to add a little fuel to it and slosh it around a few times and drain it. When a kit doesn’t cost much they skip the cleaning step because it saves a few pennies.
this is ABSOLUTELY true !!!, thank you, I often give advice for people wanting/getting a motor and I give pretty detailed advice usually, but I never thought to add that little bit, Delaney, thank you for reminding me :)
L no kin

hahaha speaking of cleaning out these cheap kits, people have found newspaper in the crank case. Definitely worth it to take an hour tearing it down before installing
That was what I did before I installed mine... Good call
But will it run on brake cleaner and MMO?
:-p
Thank you for this recommendation!
Element45 it will probably lock up that motor lol
garrett smith it will run for sure I’ve messed up some 2strokes that way
It'd be a shame to blow up the motor after all that work putting to together.....looked like too much fun to blow it!
garrett smith of course but only for a minute or two if that lol because as u know a two stroke has oil in the gas which goes through the top. End to lubricat it
I just installed the engine kit on my stationary exercise bike! Works great. Also put one on my electric bike!
Thanks for the feedback.
You always make your videos so easy to understand! I would love watching more "how to" videos if you can find more kits to build!
Thank you very much!
Yet again another solid video!
Can't Wait To See More!
Keep It up!
Thank you!

IK that feeling 😂
These are excellent engines if you know what you are getting into. I just built a 66cc motorized bmx bike that is capable of turning 9000rpms.
Thank you
FYI the needle bearing of a elite50 Honda scooter from the 80s fits where the piston goes to the crank arm also some of them can be bushings which don’t do well on high rpms
Project Farm the little 100cc engines will turn 14k rpm which is insane.
how fast can you go?

Thanks for not lying about this kit and it's abilities or downplaying the actual ability and purpose of the engine it's great and you had a pretty good video
Thanks!
He has a solution for everything 👌🏻👌🏻✔️
My friend has one of these, a good porting job+KX65 expansion chamber really wakes them up alongside a reed valve.
Project farm does everything i wanted to do as a kid, like having a motorized bike that's why I love these videos
My dad fixed up a USSR-era 2 stroke bike and it still runs like a dream 30+ years later.
Thanks for the feedback.
i reckon they're great, that one is no where near as good as the high performance model of it which is only $40 more and for that extra price you get a ton more quality, power and speed, however after using these engines to get from school and back for 3 years i copped a $2000 fine for riding an unregistered 'motorbike' with no license on a footpath next to a road, so thats the other side of it, so look into the laws in your country before buying said kit, its pretty rough copping a fine that big, espcially if you dont have a job, and after the amount of time spent making and fixing the bike, you get pretty attached, i ended up spending a total of about $500 (minus fuel) buying a custom bike, upgrading to the high performance engine, managed to sell it for half of that, but apart from all that it was a brilliant bike!
Thanks for sharing.
$2000 fine my ass, I would get an attorney. What country are you in FFS?
I don't buy the fine either. In the US anyway, under 50CC doesn't need registered. Riding on a walking path will get you in trouble, but not $2000 trouble.
@@brendanberry7403 i promise you i got the fine haha, im in australia, was riding an 80cc 2 stroke, got fined for riding on the sidewalk next to a road which counts as being on the road apparantly, for riding an unregistered, unsafe vehicle, im unlicensed which is relevant because i was next to the road, and i didnt have a helmet on. the fine came as quite a shock because i'd talked to multiple cops about it before and they just thought that "it was cool" or " i wish i had one when i was younger" but then one day around when australia was pretty much on fire i flew past a cop, doing about 40-60kph, was my fault, i shoulda worn a helmet and been more cautious
@@M1Anut im in australia, i promise you that i really did get that fine, i wish i was lying man, it put a dint in my bank for sure, check the response i gave to brendan berry for more details
Good idea on the PVC piece for the cables.
Thank you!
You certainly know your stuff, very skilled mechanic!
Thank you
It's a very simple build
Sandy Carree yeah, but you would be surprised by how many people can't even raise a seat post.
They make a 2 stroke smokeless oil now which will cut down on all the smoke, and the other thing with 2 stores rev-Em high they like that! Great job!
Thanks! Thanks for sharing.
Everytime I watch another one of your videos, I love this channel even more
Thank you!
I have one of these kits, but never got around to building the bloody thing. This video has rekindled my interest. ;)
Hope you enjoy the kit! It's a pretty easy build.
They are a lot of fun, I recommend getting rid of the tensioner. Nothing but trouble and dangerous.
VauxhallViva1975 I got mine installed after 1.5 years. It is so much fun!
Even after this, I still have not unpacked it! I will try to do that this weekend.
ccarroll.......it would be nice to have a good generator combo tensioner with good bearings
Braaap, can't wait for more 2 stroke stuff!
Thank you!
Put one of these on a crappy bike in high school and had some good times. Definitely worth it
Thanks for sharing.
Great little DUI bike it beats pushing a baby stroller around yucca valley California.
Great point.

Excellent point as my license was suspended for 8 years and two years ago I got a 49cc scooter and almost got myself arrested so now I'm afraid of motorized bicycles
Here in the great state of pa the dicks made sure us criminal dui offenders can't even ride one of these on street legally.
You should do more on the 2 stroke engine! What are its limits? And what kind of upgrade would it take to get it (safely) up to 35 or 40mph?
Thank you for this idea!
You may be interested in 2-stroke Stuffing's videos. He's tested a lot of mods and upgrades on his bike on a dyno., Evidently the best mod is just removing the baffle or complete end cap from the exhaust.
Anyway, most go 35 straight out of the box after the break-in period. Personally the best upgrades you can do for the money would be the chain($22 gets you 10ft of #41 chain from Tractor Supply which makes 2 chains that are exponentially stronger than the original) and an engine mounted spring chain tensioner (can be bought for $20 shipped if you shop around on eBay) which is so much better than the stock one that constantly shifts, and sometimes is even shoved right into the spokes of the rear wheel while moving. For reliability and safety I'd call these two things imperative.
none.
Brakes, suspension, new bars and probably rims and tires lol
Monkey J thanks for bringing the tensioner into the spokes situation up. I just checked mine and the bolt shank is clearing by 1/4". Securing the tensioner from rotating on the fork leg to keep it out of the spokes is imperative.
Most states require a motorized vehicle to be registered if used on the road, not sure about drivers license. I'll stick with my motorcycles! But thanks for the education I've learned a lot from watching your videos!
You are welcome!
Great build, and it’s videos like these that keep my son interested in your content. As much as I love the penetrating oil tests, it’s not as exciting for a 14 year old. Thanks again from a happy, long time subscriber! Happy New Year!
Thanks and you are welcome! Happy New Year!
because of how 2 stroke engines use the fuel/oil mix to lube, much of it burns off but still leaves some residue, most oil additives are designed for 4 stroke motors, using oil additives in 2 strokes can not only REDUCE the efficiency of the fuel burning off, but the residues themselves actually increase the need for regular maintenance more frequently and CAUSE long term damage and reduction of engine life, and believe it or not, using full or blend synthetic oils in the fuel/oil also REDUCE fuel efficiency because of the higher resistance to high heat and ignition, a strait up proprietary, pure 2-stroke oil and shell premium with nitrogen is best.
also, do not use fuel additives that add octane, on small 2 stroke engines they serve no purpose, the compression is not sufficient enough to be of any benefit.
DO NOT use fuel additives that have lots of detergents, except when doing breakdown maintenance, the engine relies heavily on the oil residue to lubricate and detergent additives in oils break down that function causing increased wear and tear, increasing the frequency of maintenance and reducing engine life.
if you insist on using a supplemented oil (an oil with additives) or oil additives anyway, NEVER, EVER, EVER use ones that have or add metallic and/or flammable substances such as zinc and phosphorus, these are optimized for 4 stroke engines, because 2 stoke engines burn off the oils, the metallic additives create deposits that actually damage the piston walls and rings, further increasing the need for breakdown maintenance and reducing engine life, as for flammable additives such as phosphorus and sulphates, these burning off in the engine create acids and cause severe corrosion in these smaller engines especially.
keep your oils and fuels as pure as possible and it will help greatly
when you intend on storing your bike for more than 60 days, empty the fuel tank and add a fuel stabilizer but NO oil, when you decide to go and ride again, add the requisite amount of oil, then idle the engine for 10 minutes, shut down for 30-45+ minutes for cool down, then go and have fun
try and remember, "2 stroke" & "4 stroke" are NOT numbers, they are completely different types of engines, and need to be treated as such.
I do recommend an oil additive called 'nanolub csx', but NOT for mixing in the fuel, it makes an AWSOME lubricant for external moving parts on the engine and bicycle and chain, may your bikes "Live Long & Prosper"
Thanks for this information and recommendations.
addendum to the storage tips: when you empty the tank, do fill up the tank halfway with fresh premium fuel (unmixed) then add the stabilizer, when preparing to restart, then fill the tank with premium and add your oil
Mr. Derek, rephrase your question, it's kind of confusing
Excellent, Hewitt
I agree with you, but please learn how to use punctuation properly. Your entire post is strung together with commas, which makes it hard to tell where one thought ends and the next begins.
Oh here we go... All negative comments need not apply! Especially if you've never owned, built, and ridden one!
Thank you!
theone2be33 These kits do what they're made to do. I think the problem is that people have too high expectations.
sickbikeparts.com/standard-2-stroke-shifter-kit/ if you have one do this OMG the usabilty increases 10x
What's negative to say? I bought a kit on eBay for $69 shipped to my door in three days. Hell, the guy was even nice enough to refund half the cost of a new better chain when the original one kept falling apart. Couple that kit with a nice inexpensive fixer upper and $60 in upgrades and you've got a fairly reliable mode of transportation that is much more fun than simply pedaling around town, and a whole lot easier around here. I mean where else can you find a sub $200 vehicle that needs $9 registration, no inspection, and gets 75-150mpg when gas is nearing $3 again? I don't see what there is to not like honestly, or what you could even get inflated expectations over. I mean if you expect a proper motorcycle buy a proper motorcycle (which is admittedly what some people should do, considering they spend $1000+ on what is in the end just a bike with a motor no matter how you look at it), but in the intended form, which as far as I'm concerned is an inexpensive mode of transportation, they do precisely what they're designed to do and do it at a price point pretty much nothing else can other than maybe one of those little battery powered RAZR scooters -_-
Cool video.👍 There are lots of upgrades too for these bicycle motor kits.
Thank you!
