Denville Police Department Reminds Residents About E-Bike and Mini Bike Laws
Denville, NJ — September 22, 2025 — As fall approaches and warmer weather continues to create ideal conditions for biking, the Denville Police Department reminds motorists, cyclists, and pedestrians to share the road safely. Increased bicycle and pedestrian traffic requires every driver’s full attention to prevent crashes and keep our community safe.
The department also wishes to clarify state and local laws regarding electric bicycles (E-bikes) and minibikes. With their growing popularity—especially among younger riders—there is widespread misinformation about what’s legal. Our goal is to ensure parents and community members stay informed and safe.

E-Bike Classifications
Under New Jersey law, E-bikes are classified into three categories, and manufacturers are required to attach a permanent label showing the classification, top assisted speed, and motor wattage. Many online retailers—including Amazon and Walmart—sell E-bikes without these required labels or with speeds exceeding legal limits. While such bikes can be used on private property, buyers should understand how they are regulated on public roadways.
Class 1 (Pedal Assist Only)

• No throttle; motor engages only when pedaling
• Maximum assisted speed: 20 mph
• No age restriction, but riders must follow all bicycle laws

Class 2 (Throttle and Pedal Assist)

• Includes a throttle option
• Maximum assisted speed: 20 mph
• May be treated as scooters or mopeds under state law
• Registration, insurance, and a valid moped license may be required if speed exceeds 20 mph or motor exceeds 750 watts/50cc

Class 3 (High-Speed Pedal Assist/Throttle)

• Pedal assist and throttle; maximum assisted speed: 28 mph
• Must be registered and insured as a low-speed vehicle
• E-bikes exceeding 28 mph are prohibited on all public roadways

Mini Bike Laws
Mini bikes—both gas and electric—are also gaining popularity. These bikes vary widely in design, power, and speed, with some modified models exceeding 60–100 mph.
New Jersey law prohibits operating mini bikes on public property, including streets and sidewalks. It is also illegal to allow others to operate mini bikes on public property or on private property without the owner’s explicit permission. Stay Informed
The Denville Police Department encourages parents and residents to educate themselves about E-bike and mini bike regulations. Additional resources and information are available at www.denvillepolice.org. About the Denville Police Department:
