electric bikes?

what are the laws regarding electric bikesincuding eastcleveland euclid


Answer
Depends what kind of bikes you're talking about.

Electric bicycles have the same laws as regular bicycles.

For electric scooters and mopeds, it depends on your local laws. In California, if you have a stand-up scooter that doesn't go faster than 20 mph, anyone can ride it and you just need a helmet. The same is true for a sit-down moped with pedals that only goes 20 mph. If you have a moped without pedals and/or can go faster than 20 mph, you need a Class M motorcycle license. But that's just California.

Answer
hi, i recommend buy a electric bike conversion kits to convert it . But please note some notes,
1. Does the motor fit for your bike ? I mean that you need to measure your bike drop out , and confirm it with the seller .
2. Confirm the right wheel size with your seller . You can confirm your bike wheel size according to your bike tires , such 26 x .... , 700c x ... It means your bike is 26inch, or your bike wheel is 700c .
3. The speed 70kph is very fast, so you need to make sure that your bike frame is good enough .
I recommend that the 1500w hub motor for your bike . Its speed is about 70kph with 26inch wheel, and the controller max current is about 40 amp .
