Default Re: Custom Bike Problems

You can use all 7 gears but you'll still need a reduction ratio of around 14:1 for the middle gear. You need to give us information on your gearing. A bigger motor with the wrong gearing will fry the clutch too.

Also a bigger motor will destroy the little bicycle chain and cassette sprockets. You need to decide whether you want to shift gears with the little motor, or move up to a larger one using single speed, cvt, or 2-speed auto.
I don't always listen to Alice in Chains..... but when I do, SO DO THE NEIGHBORS
212cc 2-speed
