Electric bikes are considered bicycles and can be used in the same way as a pedal-only bicycle in most locations across the US. There are local areas with restrictions on ebike use, though, so users must be aware of ebike laws in their local area and places they plan to ride.
Users should check the local regulations on ebike peak power (normally 750 watts* in the U.S.) and top speeds (normally 20 mph in the US) with their local transportation authority or law enforcement to be sure they are riding within the law.
Ebikes by Rad Power Bikes are "Class 2" in the US since they use a 48 volt battery and a motor capable of up to 750 watts* of output, allowing the bike to travel at high speeds (up to 20 mph) with or without pedaling.
For customers in locations where ebikes throttles are not allowed (such as some locations in Europe), we provide an on/off throttle button on all ebikes by Rad Power Bikes that disables the twist grip throttle to allow their use to conform to those local regulations. The pedal assist system is still fully functional when the throttle is disabled.

Notice: Riders must ride safely and respect the laws governing electric bike use where they ride. Always know the rules of the road, operate the bike within local and all applicable laws, and ride responsibly and with respect for other people, cyclists, vehicles, etc.
