how to make a 24 volt electric bike?
I want to make an electric bike but i would really only want to buy one 24 volt battery(to keep weight down and for money issues) but i was wondering how fast i could go with that and i would only be using it to get around my neighborhood cause i don't have a drivers license(only 13) and i still want it to go fast and i was wondering if i could put a transformer on it so i could use a 48 volt motor. i want to keep the cost really low because i don't get that much money not having a job and stuff like that. i have and old bike that i was going to use. i actually have 2 old bikes but one is a geared one and one is not. i was also wondering if i would use the geared one and use the gears instead of a throttle controller and just switch gears to change speeds? i really want to keep the cost down and any suggestions is welcomed. if i get enough feedback and make one i will post and 'ible.
thanks for your help!!
