Frequently Asked Questions
What are the e-Bike traffic rules for Colorado State?
Being in Colorado, Denver is subject to the Colorado Department of Transportation’s (CDOT) regulations regarding electric bike usage. This E-Bike Safety Campaign was designed to encourage the safe usage of electric bicycles across the state of Colorado. It includes a combination of digital and print educational documents focused on legal compliance and e-Bike safety.
Here are the main state laws:
Colorado uses a three-class electric bike system: Class 1, Class 2, and Class 3
- Helmets are legally required for all Class 3 riders
- Class 1 and Class 2 e-Bikes can generally be used wherever traditional bicycles are permitted
- Class 3 e-Bikes are usually restricted to roads, highways, and specifically designated bike paths
Legal e-Bikes in Colorado must:
- Have operable pedals
- Use a motor rated at 750 watts or less
- Remain within the legal speed limits for their class
Additional points to note:
- Any electric bike exceeding 28 mph or 750 watts is classified as an e-Moto or motor vehicle. (E-Motos require registration, insurance, and a valid driver’s license.)
- Modifying an e-Bike beyond factory speed or power limits is illegal and can result in fines.
- Colorado law requires sellers to clearly disclose the bike’s class, top assisted speed, and motor wattage at the point of sale.
However, Denver has established its own local ordinances and additional regulations regarding e-Bike usage in the city in response to crash statistics and conflicts over public space on streets and sidewalks.
How does Denver classify an electric bicycle?
Denver adheres to Colorado State’s three e-Bike class systems (Class 1, Class 2, and Class 3) to classify bicycles with electric assistance.
- Class 1 electric assist bicycle: Pedal-assist only with a maximum speed of 20 mph.
- Class 2 electric assist bicycle: Throttle and pedal assist with a maximum speed of 20 mph.
- Class 3 electric assist bicycle: Pedal assist only with a maximum speed of 28 mph. Riders must be at least 16 years old, and helmets are mandatory.
Can I ride an electric bike on a sidewalk in Denver?
Electric bikes are not allowed on sidewalks apart from the following exceptions:
- The sidewalk must be part of a designated bike route
- The operator is preparing to dismount and park the bike in the current location or block
When on a sidewalk, riders must always yield the right of way to pedestrians and there is a general speed limit of 6 mph.
Are lights and reflectors a legal requirement in Denver?
Electric bikes being used from dusk until dawn must have:
- A front light
- A rear red reflector
- Reflective material on the sides of the bike
What is the new sidewalk detection technology around shared e-Bike usage in Denver?
On May 21, 2025, Denver City passed a local ordinance requiring shared e-scooters and shared e-Bikes operating in the city to have sidewalk detection technology and to be parked in specific designated locations.
The ordinance is due to take effect from July 1, 2026, and applies to Veo, the vendor operating Denver City’s shared e-Bike and e-scooter programme.
The purpose of the technology is to keep shared e-scooter and shared e-Bike riders off sidewalks and reduce congestion in high-traffic pedestrian areas such as Five Points and downtown Denver.
When users ride shared electric bikes or scooters on sidewalks, they may hear an audio warning telling them to get off the sidewalk. The technology can also slow the bike down, stop it, or end the ride completely. Repeated violations may result in account suspension, educational tutorials, quizzes, or fines.
What is Denver’s local ordinance around parking shared e-Bikes?
Denver has introduced stricter parking rules due to concerns around shared electric bikes being abandoned irresponsibly on sidewalks and public streets, creating trip hazards and accessibility problems.
As a result, the new ordinance requires shared bike users to park bikes in mandatory parking zones, particularly in downtown Union Station and Central Business District neighborhoods. Shared bike users cannot end their rides until the bike is parked correctly.
