Well i am hoping i am putting this thread corretly now. i got a lot of batteries over that i wanna do something fun with. got an old bike at home with a broken engine etc, been sitting in my garage for 10+ years. (it is a derbi gpr nude 50cc).
I might want to try and put an electric motor on it and just try and learn stuffs and experiment. no real goals but a top speed of 50km/h would be nice.
what i find locally are some brushless dc motors ranging from 2-3kw with some kind of a control unit. but there are some different voltages for the same amount of power. i guess more voltage means less amps in the motor to achive the same amount of power.
When i have the opperuinity to pick parts and don't have to really adapt it to fit any preexisting electrical system - is there any voltage preferations? or should i just look on the pure power and pick whatever and build the battery pack to fit that?
if i understand it correctly i will need:
1: A motor, with a sproket (to keep it chain driven, i don't find any prices on hubs, but i am expecting it to be rather expensive compared to this ev scooter / gocart engines etc)
2: controller unit for the motor
3: some kind of throttle unit, to the handle bar.
4: batteries and bms (need bms only depending on what voltage i need)
5: charger (have up to 90V cc/cv).

Everything in that kit is kinda what i need right? i have no idea of prices, i just want something fun to ride down to the beach and in the close proximity of my home (incase something happen and i need to push it home i don't wanna be very far away at first)
