I am really surprised that know one else has tried to modify the chain tensioners that come with these bikes. I built 3 motor bike kits and did not like the tensioner from day one! I designed a spring tensioner that quiets the chain slap completely. It so simple to make, i would suggest everyone make one : ). Nice build! hows it running for you?
@ahmedahmedahmed94 You can make them faster. One of the big limitations is that they only come with one gear, and it's a pretty low gear. I replaced my stock 44 tooth rear sprocket for a 36 tooth one. On flat ground I usually can do around 37mph. A shift kit would be the best,but they cost about as much as the engine kits do.
I read somewhere also that chinese factories were marketing 68cc motors as 80cc but you also have to understand that the same regulations are different in china than the us so what qualifies as 80cc in the east is a 68cc in the west. Regardless the generic crap sold on ebay doesn't compare to a quality motor.
In asia the engine displacement is measured with the cylinder displacement plus the area in the head which is above the cylinder. An 80cc engine to them is a 66cc engine here. Which is what i think you were just saying, but just to clarify.
@mtnbiker432 Thank you for the clear explanation, this is soemthing i already know, but some do not. anyhoo some say that this bike is SLOW, i disagree. he ? said he had ridden it maybe 5 times, this engine has yet to be broken in. it will get faster. i dont know how much faster, i also dont know what bike this is, ( can have an affect on speed of bike, so can riding terrain as well. i get 30+ out of a 50cc engine
Been riding my motored bike for a few years in Boston and no cop has ever bothered me (*knock wood). Easy ride to work flying past the traffic not breaking a sweat, no looking for a parking spot2 bucks for gas for a whole month. FUN! Making your own motored bike is awesome
Dang straight. Good job. The Sunset is a great place to ride. Have you tried to ride Quintara from 24th ave to the Beach? It's a game in the Sunset called Sunset Roullette. I'm working on a Felt 40th ann. bike and just got my motor kit but the vendor forgot the sproket so I guess I'll have to wait until Monday...
so whats wrong with it attracting attention, it's legal, because it can still be pedaled which means it doesn't have to be registered or insured, and you don't need a license
it will go up the hill without the need of assist ! I typically go up a hill near my area (35 degrees) without any assisting. I like to assist though, so I save some gas. Now I bet it can tackle a 45 degree hill fairly well (probably best to help at that point). But I generally tackle anywhere from 15 - 35 degree hills with no problem with my 80cc motor kit.
i bought 1 from ebay.I would recomend it...I had to drill a hole through the frame twice.once for the engine mount and another for the ground. i did it all myself with a very powerful milwaki drill. i wouldent waste my time with a battery operated drill.
Umm i want this for my birthday
