OCHII Bicycle Motor Kit, 53CC Bike Bicycle Motorized 4 Stroke Cycle Petrol Gas Engine Motor Kit Set, DIY Four-Speed Bike Refit, Starting System Recoil Starter (Black)

It arrived with in a few day's. It's way bettered than I expected to be, it fit like a glove, the quality and power it has, blew me away. I'm super happy with it and how fast it is, I got it up to 42mph, it made my eye's tear up. No regrets at all. I Definitely would buy it again, if I were going to build another one. It comes as a kit, everything you'll need to install it.

New to motorized bikes but I was able to install it pretty easily. I love it and try to ride every day. Take your time and watch as many videos as possible. Measure everything several times and take potential clearance issues into account.Don’t be afraid to do some light customization.Almost forgot to mention, I replaced the gas tank, mine was leaking. But I had intended to do that anyway because I wanted a 1 gal. Tank.

Very happy with this engine kit.

Not sure if the clutch problem will be resolved until replacement timing belt is here. One thing leads to the next and here I get to do my own repairs on a new product. No wonder when you figure the price for the 49cc 4 stroke is way low right now. Get your fix-it tools ready for several issues mostly real cheap kit parts.

2 starts for now... Just got it to day will keep you up to date.. Thx
