You have 2 types:
e bikes like this:
Owned buy people who don't have cars or have lost there drivers license because of a DUI. Many come with pedals but are taken off because riders claim when doing sharp turns they hit the ground and crash. But it's really because they are too lazy to drive.
Then you have electric bikes like this:
They use many standard bike parts. Cost anywhere for a couple of thousand to 10K plus. Max speed allowed in BC is 26 KM but you can easily change a setting to go faster. One guy I was talking to who sells them said his bikes can go 46KM a hour. They have 3 modes. 100% pedal, pedal assist when you need spome help, and 100% motor.
This one can go 80 KM/H with a range of 60 KM.
