So this was my first motorized bicycle which I expected there may be some issues with due to lack of experience. I am using a beach cruiser I had in the backyard and an 80cc engine kit I purchased from PCC Motors. First I sanded off the original paint and any rust I found, then applied the new paint (Rustoleum).
I purchased a brand new chain for the manual pedals and installed it. After securing the engine and the rest of the parts, I took it on my first, and incredibly short, ride. As I was cruising along the chain slipped causing the back wheel to lock up which snapped the rear axle as well as the master link of the engine chain. I then took the bike to my nearest bike shop and had them install a new rear wheel, this time with no coaster brake, as well as a handbrake. I also had the mechanic there install the engine sprocket for me as he had more experience doing so.
After tinkering around with the throttle we had the bike up and running yesterday just fine. I took it on a short 3 block ride when the chain fell off once again. I hooked it back up, increased the chain tension slightly, and had no further problems for another 7 blocks or so.
The chain slipped once more and the rear wheel locked up, this time being forcefully jerked by the engine about 5 inches out of the frame to the left. (My knee hurts a lot now.) When this happened the muffler bent down and slightly horizontal and had broken off at the weld.
What should I do??? (Pictures soon)
