Hello all, I am new to motorized bicycles and even to engines I hope to learn more of these stuff here in this site, to improve my built bike with a generic Chinese 49cc engine kit. Right now here is what I did on my bike. Added a front seat and footrest for my 3 yr old son. Placed the tank on a back carrier. It's just a regular mountain bike but it does the job well for me. Just cruising slowly for safety, checking parts before and after riding. Maybe if I find a better bike here in Manila I will build another one, hopefully a Schwinn stingray or same setup. Mabuhay!
