I'm hoping someone can point me in the right direction to build a bike. I want to build a lightweight simple cheap bike (I know those requirements are not synonymous ). My roundtrip commute to work is about 4.4 miles so I only need a range of about 5 miles give or take, and there's one or two short small hills on the way that I can pedal on.
My idea is to buy a used lightweight racing BMX bike and put a lightweight hub motor on the rear. From what I've read A123 cells are the way to go. I'd like to custom mount them and the controller in the frame triangle and cover the sides with some kind of covering so it wouldn't really look like an e-bike and it would be lightweight. I think I probably want to go around 20-30mph and have a range of 5 miles and I think I can get by with the stock brake(s). What should I be looking at as far as how many cells volts and amps, and cells etc? I saw somewhere a while back that someone had a lightweight motor. Can someone point me in the right direction? I am fairly familiar with electronics and have had several small model aircraft with lipos but am new to the e-bike thing. What kind of dollars am I looking at? Thanks.
