Here are some pictures of my bikes. All 70cc 2-strokes but the Schwinn will be a Honda 50cc 4-stroke as soon as I can get the kit. The Giant Elwood is my most recent - finished it today and it has 700c wheels which make it very smooth and noticeably faster but I pedal harder on big hills. If it gets too much on the hills I'll put a 48 tooth sprocket on it but I don't think I'll need to. The carby floods when I open the throttle but I'm sure someone will help me fix that problem. The tandem has no motor because my passenger does the pedalling!
