next step go shoping for parts: battery, motor, etc...  pictured here is some trojan t105 6 volt battery, one of the best batteries for the price, if you have the room to fit 8 to 12 or more on your bike, however i think i will use the trojan t1275 12 volt club car battery, since this is a mid-size bike, i hope to make another larger bike, with t105s.  if i can fit 16 of them on a bike with a trany that keeps the amps low, it should have a good range but that might be a bit much
