E-Bike Safety
As the weather warms, we have seen an increase in the use of electric bicycles (e-bikes) across the county. However, under Wisconsin law, certain requirements need to be met to be declared an e-bike. Some of these vehicles are actually electric dirt bikes and are classified as Off-Highway Motorcycles (OHMs or E-motos) not bicycles.
Under Wisconsin law, an electric bicycle (e-bike) must:
Have fully operational pedals capable of being powered by human effort
Have an electric motor of 750 watts or less
Fall into one of the following classifications:
🔹Class 1 E-Bike
• Pedal-assist only
• Motor assistance stops at 20 mph
• No throttle
🔹 Class 2 E-Bike
• Throttle-assisted (can operate with or without pedaling)
• Motor assistance stops at 20 mph
🔹 Class 3 E-Bike
• Pedal-assist only
• Motor assistance stops at 28 mph
• No person under the age of 16 may operate a Class 3 E-bike
No pedals = NOT an e-bike under Wisconsin law.
Many electric dirt bikes are classified as Off-Highway Motorcycles (OHMs) and are regulated differently under Wisconsin law through the Wisconsin DNR. This includes rules on where they can be operated, rider age requirements, and registration. Unlike traditional e-bikes, many of these electric dirt bikes weigh over 100 pounds and can reach speeds exceeding 65 mph.
As we continue into the summer months, deputies will be out promoting safe riding and educating riders on the law. Violations may result in warnings, citations, or other enforcement action when appropriate.
If you are unsure how your electric bike is classified, please contact your local law enforcement agency or the Wisconsin DNR.
