This is my first build and I plan to purchase a manic mechanic hub adapter for this build. I want to have a cruising speed of about 35 mph(if that is even possible) i have emailed terry from blow by you and he seems like a good guy to buy from. Problem is that he only has what i believe to be a starfire 48cc and 58cc. He also has the zoom bike 48 and 80. Are any of these going to make me happy? Or should I buy from gasbike or kingmotorbikes and get the grubby gt5? Thanks for the replies!!!
