My kid wants a battery bike, i dont know much about them.
Ask me about vintage columbus or 531 with campy or dura ace and i can tell you all about it...
Anyway he needs a city bike with good hill ability.
I am thinking about getting a bafang 750w kit with crank drive instead of a wheel motor. What do you all think?
I think a kid should learn to ride un assisted. Just get him a good rode or gravel bike and let him learn to use gears.
E bikes are expensive and heavy if he has to pedal it when the battery dies.
So for an e-bike newbie some general truisms.
Higher voltage (24/36/48) = higher power, higher top speed.
Lead acid batteries are cheaper but bigger and heavier than LIPO, LIFE (lithium).
State/city laws vary, check yours. Some state anything that is self-propelled is a moped, requiring a moped permit. Others may state a threshold on the power of the motor (500W, 750W) determines something (license to operate, registration, etc.), or a max top speed (15mph, 20mph, ...) is the trigger.
