Class 1, 2, and 3 E-Bikes Explained: Which One Is Right for You?
Class 1 e-bikes assist only while you pedal, up to 20 mph. Class 2 add a throttle, also capped at 20 mph. Class 3 assist while pedaling up to 28 mph and often carry age, helmet, and path restrictions. Most states use this system, but some, including Pennsylvania and New Jersey, use their own rules.
The three-class system gives riders, lawmakers, and trail managers a shared language for e-bikes. You’ll see the class on almost every spec sheet and, increasingly, on a sticker on the frame.
The three classes
| How the motor helps | Assist stops at | Throttle? | |
|---|---|---|---|
| Class 1 | Only while pedaling | 20 mph | No |
| Class 2 | Pedaling or throttle | 20 mph | Yes |
| Class 3 | Only while pedaling | 28 mph | Generally no |
In most class-system states, motors are limited to 750 watts. You can ride faster than the cutoff by pedaling harder or going downhill. The motor just stops helping.
Which class fits which rider
- Class 1: the most widely accepted on bike paths and mountain bike trails. Best for trail riders and anyone wanting maximum access.
- Class 2: the throttle helps with starts, heavy loads, and tired legs. Great for casual riders and errands. See what a throttle does.
- Class 3: built for faster commuting on roads. Many states set a minimum age (often 16), require helmets, and keep them off some multi-use paths.
Where you can ride depends on more than state law
The state may define what your bike is, but a park, county, town, or federal agency decides whether you can ride it on a particular path. Class 1 bikes get the broadest access; Class 3 the narrowest.
Pennsylvania does it differently
Pennsylvania doesn’t use the class system in its law. Instead, it defines a "pedalcycle with electric assist": operable pedals, a weight of 100 pounds or less, a motor of 750 watts or less, and a top motor-powered speed of 20 mph. Riders must be at least 16. A bike that meets the definition is treated like a regular bicycle. Class 1 and 2 bikes generally fit. Class 3 bikes can fall outside it, so check the specs. Details in our Pennsylvania guide.
New Jersey changed its rules in 2026
New Jersey replaced its class-based approach with a stricter system that took full effect on July 19, 2026. E-bikes now need registration, riders need a license, and throttle-equipped bikes and faster pedal-assist bikes are treated as motorized bicycles that also need insurance. See do you need a license for an e-bike?
Check the label and the specs
Many bikes let you change settings, such as unlocking a higher speed. Changing the bike can change its legal class. Ride it the way it’s labeled and you avoid most problems.
