I'm hoping this has already been done by someone... using a moped engine to power a bicycle. Here's the deal: I've been on the lookout for donor mopeds to strip for parts to use on my builds... namely front suspension forks, wheels to rebuild into 26" rims, throttle controls, headlights, speedometers, handlebars etc. So far I have found two. One is an 87 AMF which is going to get left as smaller bike and will get a China girl motor. I paid $45.00 for it. Yesterday I picked up a 1995 Tomos for $125.00. The engine runs nicely, but it is so cold here I can't fool with this bike much at all, and certainly not get it ready to ride. I thought about just fixing it and reselling it, but after doing some research I started thinking about how nice it would be to use that engine on a motored bike build. Here's why. It is two stroke 49cc which makes it legal where I live. It has a 2 speed automatic transmission, Dellorto carburetor with reed valve and tuned exhaust. According to the Moped Army website it can easily be modified to run at 40 or more mph. It has an electrical system capable of running 12v. headlight, tail light, turn signals, brake light and horn. The pedal acts as a kick start. You put the bike up on the center stand, push down on the pedal backwards and it starts the motor. This has been sitting since summer and this morning it started up on the second try at 10 degrees outside.
If there is a way to mount this engine I think I can build a very capable bike for little money. I would swap the wheels with the ones from the AMF since it has 36 hole spokes and the drum brake hubs could be re-laced into 26" rims.
Has anyone done this? Any thoughts from you former moped guys on the feasibility of such a build? Last photo is of the AMF.
