Thank you very much! Very nice footage. I had a low quality one, and had a lot of trouble with the clutch. I am very glad you upgraded it. I wish you many enjoyable rides. Sincerely, Alicia from Sweden.
Beautiful day, beautiful area, nice bike, nice ride. I have a similar engine setup on a Huffy Cranbrook. I bent the crank arms for clearance, and installed two caliper brakes, operated by one lever. I am using the rubber sandwich on the spokes to mount the drive sprocket, and find it adequate - four builds using it, no spoken brokes so far. (Got my mords wixed up, there, for fun.)
I got one of those kits, mine is on a Kent Ridgeland. 700c bike, or in standard size a 28 inch wheel with a 44 tooth sprocket, still climbs hills good, but with a top speed of 32 mph.
Drill a hole through the chain tensioner and into the bicycle frame. Put a self-tapping screw through the hole and into the bike frame to serve as a pin to prevent the chain adjuster from loosening and rolling into your rear wheel spokes. If that happens, the spokes will break, the wheel will lock (and possibly collapse) and you'll crash.
I have 4 two stroke bikes and with regular check overs and maintenance they have caused me very little issues some have had none at all and all have been running for over 3 years so far, same jugs, pistons everything. It's highly recommended that you open up and clean the engine out, check ports and piston orientation before cranking them over!
I advise pinning the hub adapter on the 2 post side in the middle and using a non bushing belt drive transmision like a 4G. That being said if the motor is mounted solid you will have much less issues than the 2 stroke kits if riding frequently. Also the clutch with bolts in the middle of the pads will sometimes come loose meaning the clutch will grab and stall the engine. I recommend loctiting the bolts or using the other clutch type. The spring loaded tensioner with a heavier spring tack welded to the frame will probably keep the chain from coming loose.
My 4 stroke had none of the problems you mentioned. It also came from Ebay 158 and the only thing I had to do was lube the dual chain in the transmission.
Your rite about having a tool bag , have one on my schwinn jaguar 4 stroke ,monark springer forks, hairpin 3 spring saddle hub mount 44t sprocket rear rim V brakes, front disc brake flat drag handlebars ,heavy duty 12g. Spoke wheels arch spring loaded chain tensioner, what it really needs is a belt drive transmission, still using the stock single chain one ,they vibrate a lot you have to keep them loaded with lots of grease ,and yes breakdowns are to be expected just like early motorcycles .😂
Hey really nice bike man. Micargi make a great product I have a Seattle with a 49cc 4 stroke on it. Anyway I wouldn't be so quick to down eBay kits , I build Alot of bikes both 2 and 4 stroke and generally the quality of stuff on eBay is pretty solid, even if you don't really know what your looking for. Bikeberry on the other hand are scammers, never had an order from them come complete on time and not break pretty quick. They also say they are an American company, but are in fact, Chinese. All their stuff comes from china- all of it. But the point of this hobby is be safe have fun build what you like from wherever you decide to get it..... Just be careful when ordering from "big boys" like bike berry -what you see is DEFINITELY NOT always what you get. Have fun and stay safe
super Cool Bike when I was.a kid in the 1970s my Father traded his Antique Motorbike He had growing up to a old neighbor for a mini bike for me ! I’ve always felt guilty about him doing that for me because I know he had fond memories of riding that Bike during his Teenage years FYI I read a while ago. Many of the Ebay sellers. Were getting harassed on selling the bike kits because people were getting hurt Due to Favtory bike Welds coming apart and causing crashes ? It makes sense to me because as a kid doing Wheelies and Jumps I broke 2 necks completely off two bicycles and honestly I was a very skinny kid I do like the sound of the 4 Stroke kits and I hope to do a build myself one day as well I might gusset the neck if I feel the need to do so depending on the frame I use More likely to be a Thrift Store Special knowing me
I am seeing a lot of comments about their engines are not so good and keep breaking down etc, etc. All I know is that I got mine from EBAY and the kit came from U-MOTO. It's a two stroker 66 cc or whatever, I don't really remember, and this thing is AMAZING. I got it almost 3 years ago. It came with a Roadmaster 18 speed mountain bike (It may be 21 speed I forget). The whole thing was around $250.00. I'm getting around 30 - 35 mph, but it may be off a little as I haven't installed the speedo yet. I've had 2 mopeds and 1 Honda cb200 motorcycle so I am pretty much sure of how my speed is from experience. I have ridden motorcycles more than a few times. And I used to ride my mopeds ALL the time in San Diego as well as in Kentucky. Who knows, I may have just been lucky with the kit I got. I'm not complaining by a long shot. I procrastinated somewhat and after I built it, things came up and I ended letting it sit for 2 years chained up out back. Recently during the fall I got it back up and running and I wish I never let it set. I shoulda been riding it everywhere. This thing is -- AWESOME --. I just about have it broken in and now winter is here. I live in Kentucky and don't do winter very well. When spring hits, I plan to add some high performance parts to it. I'm sorry if any of you out there have had problems, but the good news about that is: . . Mine works fine. . Hey --- I didn't say it was good news for you. .
i think i got the same one i spent like 120 bucks on the kit put it on a crappy bike and got about 900 miles over 3 years on mine still runs i barely ride it anymore tho only replaced the chain on it think my max flat ground speed was 34 mph its good bang for ur buck
I’ve been looking at the huasheng 144 53cc motor with the 4G from grubee. I think I’ll end up with the 79cc predator. I want a cruise speed of 25+ while still being able to tackle hills. I’m sure the huasheng would top at 30-34 but probs cruises nice at 20-25
@@treeroofgrass that is also very true. I recently took the 212 off and replaced it with the 79 I really didn't lose that much speed and I still take hills well. Overall the 79 suits me well and it doesn't look quite as nuts whenever I ride the 212 it'd get Alot of unwanted attention from the authorities
You seem to live in a rural area I would have gone with a 2 stroke instead of a 4 stroke. But overall Good looking build. 2 stroke bike kits are smaller more powerful and louder “make or break pro/con on where you ride”
YOU can add a Silencer to any 2 stroke and make just as quiet as a 4 stroke model. So the make or break theory gets thrown out the window.

I got a question sir I see that fuel tank you got on back of your bike I've been looking where you buy them things at please let me know thank you have a good day sir
I just purchased the Bikeberry kit lol, not any better, probably worse and more expensive. I had to go out and buy a new transmission because the $100 bikeberry transmission they sold me has a drive gear that is not compatible with a 415H chain for some odd reason . Fighting with bikeberry over it, they say it's perfectly fine, Even after I send them pictures, It's not even usable. And on top of that the kit didn't even come with a bottom bracket. Although the engine mounting plate is pretty good, and the cranks are a little bit nicer than I expected.
Yea, I hear ya. It's kind of a crapshoot with these bike kits. The quality is all over the place. You just have to accept that it's a project and you may have to buy things 2-3 times before you get it right.
@@franksmith7271 you have to know what to buy from them and what to stay away from. I really like the10 spoke mags that they sell.

I have a similar setup. The biggest problem I'm having is the tensioner. I've tried a few different ones and the same result, within a few miles or blocks at times the tensioner fails. I've broke and stripped out a few different bolts trying to stop it from moving

I feel your pain with the kit. Mine leaks oil and the carburetor isn’t set properly. Won’t idle without full choke. Breaking down engine for full repair.
The engine is actually a stepped shaft. So neither tapered nor straight shaft parts fit it well. The clutch is for a 5/8 straight shaft. It's sloppy, but works. The camera is a Canon M50 and a Gopro 8 for the ride footage.
@@letsgoshooting3578 thank you! I have the exact same shaft, it sucks to not be able to just buy the right replacement parts, because there are none. I rode 25 miles yesterday and came home with two broken spokes. At this point i don’t know if i should keep invest money in this one or get a proper grubee kit
I discovered BGF sells the 15mm clutch you want and also the 88mm belt trans. 87MM BGF 49cc 4-stroke clutch Flyweight Keyway engine gas motor bike | eBay BGF 88/ 87mm BELT Transmission gear box 49cc 4-stroke GAS engine motor bike 2020 | eBay
It’s been a while. How is it going, still running? My build, exact same kit, has pretty intense vibration at a certain rpm, around 20mph. It broke my chain guard, mount plate and the gas tank clamp (one after another)… Do you have vibrations?
Vibration is the bugaboo with mine, too. I made simple rubber mounts between the engine and mounting plate, and between the mounting brackets and the bike frame. This helps some, but it still lacks that splendid isolation of the machinery from the driver's position you get in the better Rolls Royces. Easier on gas, though. Oh, well... can't have everything - where would you put it?
@@stephenandloriyoung5716 tried that too, only made it worse. Ordered a smaller sprocket now, trying to avoid the rpm at all. I actually did the math and it came out, that with my setup I am at 9200rpm at 30mph. Trying a 40 tooth sprocket now
Would like to set up so it can sustain speed at 50kmh withut revvving to high on flat and slight incline would this be sufficient or should i get a 160cc and above?
It all depends on the rear sprocket size. The larger the sprocket, the quicker the engine will rev up which equals lower top speed. If your sprocket is smaller, you can run higher speeds at lower RPM at the cost of slower takeoff speed and in some cases, burning your clutch up. From what I recall, the tallest you can set up gearing on the 49cc huasheng motor is to top out at about 35mph @ 8000rpm. The 79cc predator won't rev as high as the Huasheng, but it will make much more power at lower RPM. If want a really easy cruiser that will run nice cruising speeds at low rpm and take any hills you throw at it, you'll want to run one of the larger horizontal shaft 4 strokes that have the 3/4" output shaft. That will allow you to run a torque converter which will give you a nice strong takeoff, reasonable cruising rpm, and good hill climbing power all in one. I believe the Honda GX120 and Lifan 4HP motors are the smallest displacement available with a 3/4" shaft (49cc and 79cc are both 5/8" shaft)
@@dmoore0079 i would like to pedal on my own for taking off or when reaching mild incline(keeping the purpose of a bicycle being an excersise routine )and the engine essentially my overdrive on flat road and very slight incline travelling at 40 to 60kph for long distance travelling or reaching my destination in a shorter period of time.My engine choice would be a gx160 like engine .The only things Im not sure is wether a gx160 like engine would have enough torque to sustain at certain speed and proper gear ratio?would love to hear opinions from yall.
I built a 66cc 2-stroke bike that can climb steep hills by itself, while still being able to cruise at 30mph, but it looks like a 49cc 4-stroke can do the same thing.
Can you just start off with these without pedaling up to speed first? I've heard that you'll fry the clutch if you don't pedal off from a stop before engaging the engine.
3:22 not really. All these kits come out of the same group of factories out of china. Change out the carb, the exhaust and the sprocket down to 32 tooth.
You’re going to kill yourself with those brakes. You did a good job with the engine, time to upgrade to disc or good drum brakes. Watch out for the deer.
Imadizzapointment several years ago, I purchased a hub that has a drum brake and the hub incorporates a 3 speed index shifter that does the gearing internally. I never used it for any bike projects so I cannot say whether the drum brakes are good but they certainly appeared beefy. My impression was that your installation avoided those chintzy style sprockets that attach to the spokes. In that regard, your setup is much better than any other I have seen. Did that require that you change the hub by unlacing all of the spokes and reattaching them to the new hub? That would explain why drum brakes are not feasible. Just curious how the sprocket kit attaches to the hub.
Very nice. Love the theme. Also found high temp grease helps in the coaster wheel, to keep coaster brakes from over heating and killing the bearings.
Thank you very much! Very nice footage. I had a low quality one, and had a lot of trouble with the clutch. I am very glad you upgraded it. I wish you many enjoyable rides.

@@dmoore0079 i would like to pedal on my own for taking off or when reaching mild incline(keeping the purpose of a bicycle being an excersise routine )and the engine essentially my overdrive on flat road and very slight incline travelling at 40 to 60kph for long distance travelling or reaching my destination in a shorter period of time.My engine choice would be a gx160 like engine .The only things Im not sure is wether a gx160 like engine would have enough torque to sustain at certain speed and proper gear ratio?would love to hear opinions from yall.
I built a 66cc 2-stroke bike that can climb steep hills by itself, while still being able to cruise at 30mph, but it looks like a 49cc 4-stroke can do the same thing.
Your bike is top notch. Like the gas tank.
Can you just start off with these without pedaling up to speed first? I've heard that you'll fry the clutch if you don't pedal off from a stop before engaging the engine.
Pretty sure it burns the clutch out was always told to pedal before
It shouldn't that more for two stroke engine
this seems way more refined than the 49cc 2 stroke kits
ive had mine for about a month and have already put over 60 easy miles on it.
it is
I wouldnt hit a coaster brake over 10 mph, I use the front brakes on my Hypercruiser the coaster is an accident waiting to happen.
Are you wanna sell, sir
I want to know which is better?49cc or 80cc?
4stroke is only 49cc
@@jiriboucek8332 they make 79cc 4strokes...
So you're putting a 15.875mm dia clutch on a 15mm shaft. Strange.

3:22 not really. All these kits come out of the same group of factories out of china. Change out the carb, the exhaust and the sprocket down to 32 tooth.
I would buy a bike with disc brakes!!!
It may have been unbranded..that's why..
not when it has a reduction box
You’re going to kill yourself with those brakes. You did a good job with the engine, time to upgrade to disc or good drum brakes. Watch out for the deer.
Both are not feasible, both sides have sprockets in them, so the only thing you can upgrade is the front tyres
Imadizzapointment several years ago, I purchased a hub that has a drum brake and the hub incorporates a 3 speed index shifter that does the gearing internally. I never used it for any bike projects so I cannot say whether the drum brakes are good but they certainly appeared beefy. My impression was that your installation avoided those chintzy style sprockets that attach to the spokes. In that regard, your setup is much better than any other I have seen. Did that require that you change the hub by unlacing all of the spokes and reattaching them to the new hub? That would explain why drum brakes are not feasible. Just curious how the sprocket kit attaches to the hub.
ah bike berry the company that takes your money and never ships the item they are a scam
bikeberry their products are trash
