All of our bikes in the USA market are shipped and labeled Class 2, 750W or less with max 20 mph. The factory will tune the bike through controller, motor and display to be Class 2, limited to 20 mph, performing at a maximum of 750w.

It is not the responsibility of Amp Rides to dictate to owners what they can do with their bikes after they receive them. There are modifications that owners can do on their own, at their own risk, that will increase power of motors and speed.

Amp Rides assumes no responsibility for modifications made by owners after receiving bikes. Any advertising, reviews of bike potential performance beyond factory settings of 20mph, 750w are indicating the potential for consumer to change settings when using offroad on private property while complying with all local and federal laws. It is the consumer’s responsibility to adhere to local laws when modifying the settings beyond the 750w, 20mph or less that they are shipped with. Bikes can also be adjusted to be 500w, 15mph bikes if required and those settings are available in display manuals on Owners page.

Electric Bike Laws and Regulations

There are three different classes of e-bikes. Classes were created to determine how e-bikes should be used according to local e-bike laws. Currently, 22 states across the U.S. utilize the three-class system for electric bikes. The classes include:

• Class 1: The Class 1 e-bike provides assistance only when you pedal, and stops assisting when you reach 20 mph — great for bike lanes, bike paths, roads or anywhere you'd take a traditional bike.

• Class 2: The Class 2 e-bike is equipped with a throttle which provides a boost without pedaling, and stops assisting at 20 mph.

• Class 3: The Class 3 e-bike is equipped with a speedometer, and only assists until the bike reaches 28 mph — an excellent choice for commuters. The most popular bikes fit into Class 1 or Class 3 because riders still want to pedal.
