Everything you need to make a your own Motorized Bicycle.
3 more significant differences : 1) the 49cc 4-stroke engine has a forced air cooling fan that is effective at all RPMs,the 2 stroke has no cooling system, it relies on moving the bike through the air 2) The 4-stroke has a proper lubricating system, the 2-stroke has a very poor lubricating system , so the 4-stroke should typically last much longer due to less wear 3) The gas mileage is much better with the 4-stroke. Period.
Different strokes , for different folks
Nice man
I've never heard of the 30-min ride time on 2-stroke engines. I ride mine for one and a half hours normally and never have any problems.
Its just recommended.
@@boibruh1115 same thing. But i didn't know at that time. If i knew that recommendation i wouldn't have done that.
I’m going to get the 2 stroke kit
Anu ba maganda gas tlga pag 4 stroke
I NEED A PREDATOR KIT!!!!!! been looking n waiting for ions😭😭😭
LOL 4 strokes per revolution! they are both 2 strokes per revolution. its 4 strokes per POWER cycle for a 4 stroke!
Up and down movements both count as a stroke.
2 Stroke- 1.Suck bang 2. Squeeze & Blow
4 stroke- 1. Suck 2. Squeeze 3. Bang 4. Blow
100th like
Stfu
@@Octanetroopers_01 One of us is messed up we both can't be right. I believe the two-stroke does all four cycles in the same order as the four stroke suck squeeze bang blow. It just accomplishes this in two strokes of the piston or one revolution of the crankshaft. And of course the four stroke does it in four strokes of the piston or two revolutions of the crankshaft.
You helped me answer all the questions I was thinking of. Perfect presentation thanks
Had a 2 stroke never wanted to run
Went to four stroke slower yes but less time in the garage
Plus I can just pull up to the pump and fuel up
I have gone up to 37 mph on a huasheng 49cc 4 stroke. On the crappy centrifugal clutch that sucks and can leave stranded at any moment leaving u to pedal ur butt home. But with a better transmission like the ezqmatic you can get excellent reliability from the engine. 2 strokes are good you just have to carry around 2 mix oil around with the tank to mix it not a big deal but something you got to do.
I’m a new driver…and thank u….I now am sticking with my 2 stroke….thank u…
This is exactly what I needed to see. Car broke down and need a way to get to work. May be slower with the 4 stroke, but it sounds way more reliable
Yes, my 2 stroke breaks down very often
2 stroke are faster cheaper and dirty, ride one in Cal you will get a ticket,
4 stroke last longer are cleaner, and you don't need to screw around mixing oil and gas
want to go fast get a motorcycle
Great advice! There is an engine kit which fits for everyone, whether it's 2 stroke, 4 stroke, or electric. There are advantages and disadvantages each option, and should be taken into consideration when choosing an engine kit. All of our engines are intended for recreational use, and are not intended to be used on public highways or roads.
Lol I live in Visalia, California which is in the central valley and cops don't care about 2 stroke engines as long as we wear a dot approved helmet
what if you cant get a motorcycle or dont have a drivers license yet?
@@bikeberry why are you talking about commute in the video? Haha
I prefer a briggs and stratton flathead. You can get 5 to 11 horsepower out of it. Plus the sound and reliability of a flatty bike is priceless.
You can modify the 4 strokes but the modifications are harder to do. You can port and polish, bigger carb, header pipe, bigger valves, etc.
Excellent video, thanks for the info.
Thumbs up for this great informative video. Subscribed. Full suspension mountain bike with an engine might be really nice. Would be light AF.
Very informative! Thank you much!
hi bike berry what's a high end level of theft prevention for these kits, I'm thinking of u locking my cylinder to the rack at my apartments as well as wheel to frame as well.
Why do I always watch comparison videos just after I buy something :(
Which one you got
@@integrationofmanandmachine4714 2 stroke. Theyre a.good engine but usually rip spokes off bike wheels and even broke my bikes pedal axel/gear thing
@@edg6779 yeah because the clutch just lays down alot of torque at once. While the 4 stroke gets it up to speed but wont ruin your spokes as fast
Bro that was helpful af an simple so thanks appreciate you sir have a good day
great vid very useful summary
Less maintenance on the 4 and quieter too but like you said the 2 is way more enthusiast oriented and like my two rides my choice, but i would still like to build a 4 some time soon, nice vid thanks Guys!
the 4 needs oil changes. The 2 doesnt
@@funnypranker34 yes, but the 2 stroke needs a lot more maintenance and you need to mix the oil
Thanks for the helpful video!
Looking fowatd to purchasing a two stroke from you guys next week. I have a thruster 700c fixie, which motor will work best? Please provide a link. Thank you!
excellent vid. fully enjoyed
can the 48-50cc 4 strokes with 5/8" shaft accept a Comet-style torque converter and if so would it line up well with the rear wheel sprocket? - that setup would have advantages with hilly terrain.
Can you do a video on how to install a jack shift kit ??
I am really loving you guys videos!!!!! so informative...I am looking for something to get around the campground in the summer. I have very little money to work with, and a womans cruiser bike. I was looking at your friction motors, are you getting anymore in stock? I sure do hope so ;) I am also a heavy rider...not too many hills at camp. If you have suggestions that be awesome!! Also interested in financing, but I have no credit, ive never had a credit card.:D Thanks again! love you guys!
A friction drive engine seems like the perfect fit. It's reliable and has the torque if you happen to come across hills. We recently ordered a large shipment of engines and parts to fill our inventory. Just a little more patience and we'll have you riding throughout summer.
He is wrong from the beginning.
Both engines have two strokes per revolution.
he mean to say two strokes per powerstroke
Where does the tank fuel line connect to the carb, no hoses were connected when I got the motor, there is one nipple bent downward and one straight coming from the carb and two more on the carb bowl.
Weird, online I've read that top speeds for a 4 stroke is around 20-30 mph and a 2 stroke 30-45 mph
Do you know what causes the 49 cc 4 stroke engine to be difficult to pull and start up? It takes multiple pulls and trying to soften the rope to start the engine
Hey bikeberry, I want to take a motorized bike trip from Philadelphia to Atlantic city (About 70 miles). Which engine would be best suited for the task? (and less likely to kill me) I understand 2 strokes can have a lot of performance parts or heavy duty parts that could increase reliability but 4 strokes last longer. I'm currently running a 2 stroke. what are my options ?
hey bike berry I have a schwinn JAGUAR beach cruiser it has 7 gears in the rear wheel the pedals only have one gear I want a 4 Stroke engine but I don't know what kind of kit I need with the 7 gears and also I try to look up 4 or 2 stroke instalation videos on bikes with gears (10 speed , 7 speed , mountain bikes or a bike like mine's ) but no luck do you guys know of any video or you think you guys can make a video about this it will be a big help to new customers THANKS SOON TO BE A FIRST TIME CUSTOMER AND RIDER CAN'T WAIT😆👍
Yes and I'm really digging it... Don't know if you've ever tried one or not but they sound great but they're hard to line up on a lot of bye she want to make sure you got a lot of clearance between the front tire and the bottom tube
whats the small 2 inch metal cilinder piece thats where the engine is at, around it is the sprocket that you can move with the sp sprocket tool , i lost the piece one time i forgot to adjust the screws on my 2 stroke bicicle and while riding the aluminum box went off i managed to find 1 screw and the alunimum cover purchased the screws but realize that small pin was missing. need help ca t ride it i cant press the clutch to start the engine
In the video what did you have on the 4 stroke coming off of the shaft
2-Stroke - All the power is in the top end, use more fuel, noisy, have to remember to pre mix your fuel, less reliable and harder to start in the cold. 4-Stroke, More torque and bottom end power, quieter, more fuel efficient, only have to remember to keep engine oil topped up, much more reliable and the most important thing... they don't smell as nice as 2-stroke ;) I am by no means opposed to 2-stroke, I actually love the things! I really do think they are better suited to high performance motorbikes rather than tiny bicycle engines though, especially if you live in the UK and want to get away with riding them around illegally without getting caught by the old bill :) Plus, from the figures I have seen quoted the power difference between the same capacity 2-strokes and 4-strokes is negligible, they are very cheaply made an are not tuned. Only when you start to polish ports, tweak carbs, filters, and expansion chambers (in the 2-stroke case) will you start to notice differences. Maybe if Stan Stephens starts doing a bicycle engine tuning service/kit I will be interested in the 2-stroke option LOL
Jack Hakke I got a 2 stroke with high top end speed and lots of torque. I will dust u on my 80cc 29 inch cruiser
On the 2 stroke, is that the rear gas tank you sell on you website?
thank you for this video.
Is it possible to remove the (what appears to be) plastic cover from a four stroke engine. If not, is it possible to paint it as long as I take care not to get paint on anything important. would it be possible to paint the entire engine so long as proper care it taken. I have an airbrush and am skilled in using it, so painting would not be the problem. Simply wondering if it would interfere with the operation of the motor.
4 stroke quieter, more efficient, more durable. GXH50 is the top dawg
Please Make a video on how to install electronic starter in 4 stroke bicycle engine
I have a 29” Mongoose Excursion 21 Gear Mountain Bike. What is the best motor kit for it?
Can I put my FMF Fatty from my cr125 on the 2 stroke version?
...it says they recommend 30 min ride time for a 2 stroke but I think the shortest I've ridden mine was an hour and the longest was 4...
Crazedisme me too no harm
bluckingblucker XD I blew my engine a few months ago! now I have a ninja 250 xD
Crazedisme, I ridden mine longer than 30 minutes too.
Longest I've ever run my 2 stroke was about an hour. Sometimes full throttle sometimes half. but its usually a short commute to the store and back. No issues yet.
Crazedisme
Yeah I was gonna say a half hour? How has yours held up over time?
Wow! you deserve many subscribers
anyone know what the weight limits are on these
Anyone got any decent links for chain tensioners cause the one that came with my 2 stroke is shit and keeps getting in my spokes
What size engines were you using for the estimate of speed?
Is the recommended ride time for the two stroke really only 30 mins I mean that's shit I want to take it out an ride for at least an hour or so, I just got mine an my commute to work is only 20 mins at full throttle but I've been thinking about taking it out for a cruise
is it 30 min ride time because it might overheat overwise? what if adding fans to the outside that blows onto the motor?
How can I make my 2 stoke a pull start ? Am really tierd on pedal start. Because it make my bike havey and take lots of energy
How come you guys don't collaborate with SICKBIKEPARTS and offer shift kits or show how to use them along with these kits?
Hey guys, my brake cable gets out of adjustment very quickly no matter how tight the cable is. Any ideas? I got a 2 stroke and its fun to ride.
Peter Kapica go to a bike shop, might be worn out cables, or not tightening the brake linw bolt good enough
I think that nobody realizes how simple a 2 stroke engine is, it has so few moving parts you can get out alot more power and better mpg, and if something breaks... you know what it is because its so SIMPLE and replace all parts within a few hours.
Oil in gas? just 2%! and i have a lil Tomos 50cc, i can drive up to 50km with only 1 litre... no 4 stroke beats that XD
Two strokes are great in that way but I think they make the most annoying noise conceived by man
The Piscis Its better than a car with a fartcan atleast lol
+The Piscis but smell great
McMuffinFluffin yes, my friend and I assembled one of these kits on a bike and the exhaust pipe got in the way of the pedals when it was pointing down, so we switched it to were it was pointing and now we get a good wiff of fumes every time we ride it
+Gecko Gremlin Generally, no one 2 stroke can beat 4 stroke, in terms of consumption ...
I'd like to order from you , but to Romania , the cost of transport is 600 $ , too much :( Hope you guys will open a store in EU too ! If you do have a store , I'm waiting for your reply
I have a coc schwinn XL are their motor mounts for them on bike berry ?
Abraham Perez we do but it's currently out of stock, but here is the link if you want to take a look. www.bikeberry.com/gas-engine-kits/engine-kit-parts/performance/motorized-bicycle-offset-wide-frame-chopper-mount-kit.html
Great video and great information. I just built a motorized bike with a two stroke engine. I kinda regretted why I didn't use a 4 stroke engine. After watching your video, I no longer regret LOL.
Always glad to have helped. There really isn't any wrong choice between the engines, it all comes down to what you're looking for.
good job
need to add a us forest servive approved spark arrester do u have one to add to existing mufler systems.
You dont need that shit the original 2 stroke exhaust pipe in your kit does the same thing with the baffles. On a 4 stroke the factory exhaust has it too
can you make a mini bike with a 2 stroke bike conversion kit
how many CCs was the 2 stroke in this video?
aCardboardTube 66cc
Do you have 20 inch bmx kits?
my yz 2 stroke hits 70 something, and those 4 strokes are fast too
..but it depends on the size of the motor, for the speed and power...not the strokes
Can i fit a 90cc dirtbike motor with tranny into my motorbike?
What are the CC's of these bikes?
Could you help me out, my bike was running fine then I went round corner and held the clutch in and it just cut out on me
Red Jaguar ajust you idel needle
Can you still use ypur bike with the 4
Will the Four Cycle kit give any problems size wise to my 29"s Mountain bike?
I got a 2 stroke on my 29er and it does 35 mph so no unless the frame has no space
This is very good. Ridiculously non technical but well explained.
Good Job
Is there a way that a lawnmower engine can work as well for a bicycle motor, since it's a vertical shaft will it still work if the motor is flipped horizontally?
I have seen a video that addresses that. If I recall correctly, he added some kind of metal tab that would scoop up and throw the oil to get where it needed to be. Without doing something special internally, the bearings don't get oil and will be ruined.
What is the oil for two stroke engines???
Thank You !
Can either of these bicycles be pedaled independately while the motor is off? I used to have a scooter with a similar setup as the 4 stroke, and it seems like if you're pedaling and rev the engine, it'll engage the wheel and won't disengage unless you stop. The 2 stroke seems to be always engaged unless the clutch is pulled in
Bicycles with our engine kits can be pedaled independently by locking the clutch in its disengaged position. We provide a clutch lever with a locking pin as part of our engine kit package, or can be bought separately.
is it available in India ,if yes how,please help
THE 2 STROKE WILL NOT ACCELERATE FASTER WITH ANY REAL WEIGHT OR GOING UP HILL...4 STROKE WILL PROVIDE MORE TORQUE... ADJUST GEAR RATIO TO TRANSLATE THAT INTO FASTER FLAT LAND ACCELERATION THANKS 2 STROKE...
@@brytodunsm5713 yes, yes they are
My 4 stroke vibrates like crazy and I'm not sure what's wrong,
I have a 2 stroke build that i put together earlier and that one rides alot smoother but my 4 stroke build vibrates like crazy even at idle and I'm not sure why..
what do you recommend if I do have to ride a 2 stroke longer then 30 min spray it with water or what?
That is BS ride as long as you want
Does the 2-stroke vibrate a lot due to not having rubber motor mounts?
It does a bit more
Can I put and fit this 4stoke or 2 stroke engine in moped.
It is possible, but it largely depends on the frame and how you are trying mount and drive the moped. Some modifications to the mounting and drive system may be needed.
hi this is durga from India I want to buy u r products and how to approach u
a 4 stroke ingin is composed of intake compression and power it takes a 4 stroke two revalutions of the ingin a two stroke combines exaust and power intake and compression so that it is only one revolution for each power stroke
Now I know that my "1990 vintage Hyper motorized bicycle" is a 2-stroke one. I bought it just recently from a local pawnshop for $380.00, "as is."
I had trouble turning on the engine, though, because I didn't exactly know how. I've watched another video on how to turn it on, including yours, today. Also, I didn't use a mixture of oil and gasoline on it...because I wasn't too sure about that. For a period of about 3 hours, I tried making it work. 👉 PROBLEM: They sold me the bicycle with a couple of wires loose. The one that connects to the "throttle" was disconnected. I connected one of the two wires to the blue wire that leads to the CDI box. Also, the white wire was disconnected, but I now know that it doesn't have to be connected to anything because it's optional and because it is sometimes used for connecting lights to the bicycle. 👉Another problem that I encountered was that both the gas line and the little gas filter started leaking. I need to replace those parts. 👉In the end, I decided to just come home peddling my vintage motorized bicycle, instead.
Thanks for all your vital information... and for enlightening me. From, "Curious Joe" 😼👍
whats the yowing capacity
Your information on the strokes was correct, by the manual vs automatic was wayy off. It depends on the engine you use. Most motorcycle engines for example, two or four stroke, have clutches.
The "recommended riding time" is a myth. It doesn't matter either way.
PLEASE SOMEONE HELP. I recently put my motorized bike together. Without the spark plug in, the engine wants to turn over when I release the clutch. With the sparkplug, it does NOTHING. WHATS WRONG!
hey bike berry I have a schwinn beach cruiser it has
Beach cruisers tend to work check the measurements
If i build a 2 stroke can i ride it on the road in north carolina?
Austin Watson did you ever build a motorized bicycle in north Carolina. I live here and just built one and wondering if the cops ever said anything to you
What is average of 4 stroke engine
Which one have more tork? To climb the streets
My bike is not a beach cruiser but it meets the requirements can I still use it
Yes
Kueth Khor yes I use non beach cruiser bikes
is there a way to put a clutch lever on a 4 stroke
Our 4-stroke engines do not require a clutch lever, but have heard of DIY modifications to attack a manual clutch.
Can someone please recommend a kit for a Trek 37000? Any help would be appreciated.
Cory Jones www.trekbikes.com/int/en/bikes/mountain/sport/3_series/3700_disc/ if you have this bike. The kit won't work to well with this bike because the downtube is not cylindrical!
Ah thanks for the feedback. Do you know any other ways around this or would I have to look for a new bike?
the baffle on my muffler fell off and my bike wont start will getting a new muffler fix that?? also i am not sure it is even getting spark
If its got compression, then check the cdi, you might need a new one. Also where do you store your bike and whats the weather like if stored outside
+Peter Kapica it is getting spark but no compression
+Eli's Magic sounds like bad rings to me
Wot if the frame too small 4 the engine ?!?
4 storke will last longer at a cost of a very minor loss of power. 2 stroke gives you more power but wears out quicker.
Yeah had I known the drawbacks I'd have 100% gotten a 4 stroke instead of a 2 stroke, my 2 stroke is horrendously unreliable
and what will happen if i use more than 30 minutes the 2 stroke one will the motor explode ? because yesterday i had a ride of 3 hours and i didnt see any problem
It can wear on your engine quite a bit, but it depends on how hot it is outside. Hotter it is, higher chance that there will be damages.
BikeBerrycom Yeah, don't use the stock engine head for the 2 stroke. I upgraded mine. I drive it for many hours at a time hot and cold. I have almost 3,000 miles on my bike and it starts perfectly every time. As for the 4 stroke, it's based on a honda pump motor which is meant to handle heavy* loads for long time standing still!
Where is weight , avarage size ?
bonne vidéo .. merci à l'équipe de BikeBerry ;)
Watch someone who rides a bicycles talk about internal combustion engines without going into detail or talking for more than a minute straight.mp4
lol
2 stokes can have cyntrifical clutches too brehh....i dnt think i spelled cyntrifical right tho
Wrong, Its got a dry clutch like a manual transmission car
Peter Kapica
He said "can have" these are one of only a few applications that have a manually operated clutch most 2 stroke engines use a centrifugal clutch.
Daniel Serrano it’s just the type of engine popular for the bike to motorcycle conversion
Sir the 4 stroke is push start how many horse power
Brcouse i plan 2to build 4 stroke motorized bike
My two stroke blew compression after 30km, 4 stroke kit is on its way
what does that even mean? new parts are like 15 dollars for the piston and 10 for the head. 20 for cylinder lol
