The frame cracked at some welds, the crank was so soft the pedals finally stripped beyond repair and the engine kit is currently awaiting a new bike.
It did last about a thousand miles altogether. I sold it to a guy and he rode it quite a bit, I borrowed it a few times and then I didn't hear from him for awhile.
I checked up on the bike and found that the frame had cracked and he quit riding it....so, another ''boomerang bicycle motor kit"...that's where I buy back the remnants of a bike I sold cheap, both parties are happy.
