no weld rack mounted friction drive bike?
OK I am thirteen and all of my friends have gopeds but i wanted something different so i decided that i wanted to build a motorized bike. I do have a lot of background knowledge of go-carts, mini bikes, and mini choppers. But i was wondering if it was possible to mount a go-ped motor on my bike with no welding. I thought of a rack mounted engine but when i looked them up they were all chain drive... Which isn't a big deal but i have the go-ped and the bike and don't want to spendd much more then $75 any ideas would be great. thanks (if it isn't possible just say so)
