Do States Allow E-Bikes With Throttles?
Yes, in most states. Throttle-equipped e-bikes are generally legal as Class 2 bikes when the motor stops helping at 20 mph. Restrictions show up on some trails and in some states. New Jersey now treats any throttle e-bike as a motorized bicycle needing a license, registration, and insurance. Pennsylvania allows throttles but requires pedaling on non-motorized state park and forest trails.
Throttles are one of the most popular e-bike features, and one of the most regulated. Here’s how the rules generally work across the U.S.
Throttles in class-system states
Most states use the three-class system. In those states:
- Class 2 is the throttle class. A throttle is allowed as long as motor assistance stops at 20 mph and the motor is 750 watts or less. Class 2 bikes are usually treated like bicycles.
- Class 1 and Class 3 are pedal-assist classes. They aren’t supposed to have a throttle that moves the bike beyond walking speed. Some bikes sold as Class 3 include a throttle limited to 20 mph; how states treat those varies.

Where throttles get restricted
- Trails: many mountain bike trails and some multi-use paths allow only Class 1 bikes, which rules out throttles.
- Specific states: a few states define only certain classes or use their own definitions. Massachusetts, for example, defines Class 1 and Class 2 only.
- Cities and towns: local rules can restrict where throttle bikes ride, especially on boardwalks and park paths.
New Jersey
Under New Jersey’s law that took full effect July 19, 2026, an e-bike with a throttle is classified as a motorized bicycle. That means a license, registration, a plate, and liability insurance. Pedal-assist-only bikes that stop helping at 20 mph still need a license and registration but not insurance. If you’re choosing a bike to ride in New Jersey, that difference matters. Confirm details with the NJ MVC.
Pennsylvania
Pennsylvania’s definition of an e-bike allows throttle assist, as long as the bike meets the 750-watt, 20 mph, and 100-pound limits. However, on non-motorized trails in state parks and forests, riders must pedal; throttle-only riding isn’t allowed. See our Pennsylvania trail guide.
Practical tips
- Check your state’s motor vehicle agency for its current definition.
- Check rules for the specific trails you plan to ride.
- Consider a bike that lets you disable the throttle, so you can ride where throttles are restricted.
- Don’t modify the throttle or speed limits. That can make the bike illegal and void the warranty.
