What are the e-Bike traffic rules for Colorado State?
In 2024, the Colorado Department of Transportation (CDOT) launched the E-Bike Safety Campaign designed to encourage the safe usage of electric bicycles across the state.
They have developed a digital and print educational awareness programme focused on legal compliance and e-Bike safety.
How does Colorado State classify an electric bicycle?
Colorado State uses the 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.
The CDOT safety program strongly recommends helmets irrespective of class.
What are the rules and penalties around modifying electric bikes?
Modifying the bike’s power governance system to exceed legal limits means the bike is reclassified as a motor vehicle.
Any e-Bike operator found to have engaged in this form of tampering is subject to a Class B traffic infraction in Colorado State. This penalty includes a fine of $15 and a surcharge of $6.
Where can I ride my electric bike in Colorado?
Class 1 and Class 2 e-Bikes can generally go wherever traditional bicycles are allowed, but Class 3 e-Bikes are typically restricted to roads, highways, or specifically designated bike paths.
Always check local municipal signage, as cities and local authorities may introduce additional restrictions on specific trails and recreational areas.
Are there any age restrictions on electric bike usage in Colorado?
Class 1 and Class 2 electric bikes can legally be operated by riders of all ages.
However, Class 3 electric bikes are restricted to riders aged 16 years or older.
What are Colorado’s e-Bike safety recommendations?
Along with its compliance agenda, CDOT also offers the following educational riding tips to improve safety on electric bikes:
- Educate yourself on road rules and use bike paths and bike lanes whenever possible
- Ensure you can safely mount and dismount due to the additional weight of e-Bikes
- Use working lights and reflectors so you remain visible
- Use warning devices such as bike bells
- Wear a helmet.
