Re: 50cc GY6 on a Bicycle??
Hey! I am building a fat tire (mongoose dolomite) custom frame and gas tank bike. My mandatory specs were that it had to have disc brakes front and rear, 4 stroke motor, and shift with no manual clutch (shifter kit from Bike Berry). The problem I am having seems to be that the 49cc motor (also from Bike Berry) is under powered for the gearing and is frying my centrifugal clutches. I am thinking about going with a 150cc Gy6 motor. Do you think this is the right thing to do? Perks to the Gy6 motor are that parts are readily available, speed will be more comfortable, and a kick starter. My build is more of a motorcycle style than a pedal bike. I am still trying to utilize the original rear cassette and shifter so that I may run through all 7 gears for a more useable ride. Rather than going with a larger single gear, I am thinking about using a more powerful motor. Hence the 150cc Gy6. Does anyone have any experience with using a Gy6 150 on a motorized bicycle?
While I have the bike on the stand, it will run perfectly fine and shift through the whole cassette. But while under actual load, it barely moves under its own power.
