Electric bikes are considered bicycles and can be used in the same way as a pedal only bicycle in most locations. However, there are a multitude of localities with restrictions so users must check with local law enforcement to be sure they are riding within the law. One example is NYC which has had a ban on the use of electric bikes.
Since our bikes use a 48 volt battery allowing the bike to travel at high speeds when desired, users should take extra care ensuring that they operate within the law and check their local regulations on peak power (normally 750 watts in the U.S.) and top speeds (normally 20 mph in the U.S.).
We provide an on/off throttle button on the production bikes to disable the twist grip throttle so customers in locations where e-bikes with throttles are not allowed (some locations in Europe etc) will be able to conform to local regulations. The pedal assist system is still fully functional when the throttle is disabled.
It is our job as e-bikers to obey the rules of the road so please ride responsibly. While it isn't all encompassing, here is a link to read about laws pertaining to the operation of electric bicyles:
