Ok, so I put on my engine kit to my bike, right. So everythings on, I have an older Huffy ladies model bike that I used for this. The bicycle was originally a three speed with handbrakes but I decided to boy a single speed wheel with a coaster brake, I kept the handbrakes on though. Anyways everything was going good, I put the chain on and I can't pedal. I can't pedal with the clutch pulled in, and I can't pedal it like a normal bike. In fact the rear wheel will only roll about an inch either way. Anyone know whats going on with these? Help is greatly appreciated.
