Okay ive been having problems with bending rims, bent spokes, chain snappings and anything you can think of. Im getting tired of it and want to get a friction kit. I have a 2 stroke chhina girl. I wanted to know if you can peddal start with the friction kit. and do yuo have to have a pull start? Sigh. I love the chain drive but all these problems keep happening. Id rather have my chain drive, If anyone can find me some really durable wheels that can have a mountain bike sprocket put on please let me know.
