E-bike classes and rules

By the end of this topic you can

• You can tell Class 1, Class 2 and Class 3 e-bikes apart.
• You can find the class label on an e-bike.
• You can explain why an e-bike outside the classes may be treated as a moped or motorcycle.
• You can check where each class may legally ride in your area.

What you need to know and understand

• Class 1: the motor helps only while you pedal and stops helping at 20 mph.
• Class 2: the motor can also power the bike by throttle, and stops helping at 20 mph.
• Class 3: the motor helps only while you pedal and stops helping at 28 mph.
• Most states have adopted the three-class system in some form; details vary.
• Under federal consumer product law, a low-speed electric bicycle has working pedals, a motor under 750 watts and a motor-only top speed under 20 mph.
• In California, Class 3 riders must be at least 16 and every Class 3 rider must wear a helmet.
• E-bike riders generally follow the same traffic laws as bicycle riders.

The three classes side by side

Many states require a label on the frame showing the class, top assisted speed and motor power. If a bike has been modified to go faster, or has a bigger motor than the rules allow, it may no longer count as an e-bike.

• Class 1: pedal-assist only, assistance ends at 20 mph.
• Class 2: pedal-assist and throttle, assistance ends at 20 mph.
• Class 3: pedal-assist only, assistance ends at 28 mph; often has extra age, helmet or speedometer rules.

Where you can ride

On streets, e-bikes usually ride where bicycles ride, including bike lanes, and follow the same signals, signs and right-of-way rules. That means stopping at red lights, yielding to pedestrians in crosswalks and signalling turns.

Paths and trails are where rules differ most. Class 1 and Class 2 are often allowed on paved bike paths, while Class 3 is often kept off them. California, for example, generally bars Class 3 from bike paths and trails unless local rules allow them. Parks, beaches and mountain bike trails may set their own limits. Look for signs at the entrance.

Checking your own e-bike

1. Find the class label on the frame or in the manual.
2. Check whether it has a throttle and what its top assisted speed is.
3. Look up your state's minimum age and helmet rules for that class.
4. Check local rules for the paths and trails you plan to use.
5. Do not alter the speed limiter, as this can change the bike's legal status.

Common mistakes

• Riding a Class 3 e-bike on a path where only Class 1 and 2 are allowed: read entrance signs.
• Assuming a high-powered electric bike is an e-bike: if it exceeds the limits, it may need a license and registration.
• Ignoring red lights and stop signs: e-bike riders must follow traffic laws like other road users.
• Skipping a helmet: even where the law does not require it, wear one.
