Thinking about buying an e-bike in Colorado? Before you hit the road or trail, it's important to understand Colorado's e-bike laws. Knowing where you can ride, what type of e-bike you own, and the rules that apply can help you ride safely and avoid costly mistakes.

Whether you're commuting through downtown Denver, exploring mountain trails, or enjoying a weekend ride, here's what every Colorado rider should know.

Colorado Uses a Three-Class E-Bike System

Colorado follows a three-class system that defines electric bicycles based on how they provide assistance and their maximum assisted speed.

Class 1 E-Bikes

• Pedal-assist only
• Maximum assisted speed of 20 MPH
• Generally allowed anywhere traditional bicycles are permitted

Class 2 E-Bikes

• Equipped with a throttle and pedal assist
• Maximum assisted speed of 20 MPH
• Generally allowed on roads, bike lanes, and many multi-use paths

Class 3 E-Bikes

• Pedal-assist only
• Maximum assisted speed of 28 MPH
• Riders must be at least 16 years old
• Helmets are required

Understanding your bike's classification is one of the most important steps before riding in Colorado.

What Makes an E-Bike Legal in Colorado?

To qualify as an electric bicycle under Colorado law, a bike must:

• Have fully operable pedals
• Use an electric motor rated at 750 watts or less
• Stay within the legal speed limits for its class

If a bike exceeds these limits, it may be regulated differently under Colorado law.

When Does an E-Bike Become an E-Moto?

Colorado law generally treats vehicles that exceed 750 watts or provide electric assistance beyond 28 MPH differently than standard e-bikes.

Depending on the vehicle's specifications and configuration, it may be classified as an electric motorcycle or another type of motor vehicle, which can require registration, insurance, and a valid driver's license.

Always verify your bike's classification before purchasing or riding.

Can You Ride an E-Bike on Denver Sidewalks?

In most situations, no.

Denver generally prohibits riding electric bikes on sidewalks except for a few specific situations:

• The sidewalk is part of a designated bike route.
• You're preparing to park or dismount your bicycle.

If you are riding on a sidewalk where permitted:

• Always yield to pedestrians.
• Ride slowly.
• Denver has a general sidewalk speed limit of 6 MPH.

Remember, pedestrians always have the right of way.

Where Can You Ride?

For most riders, Colorado offers plenty of places to enjoy an e-bike.

Generally, you can ride on:

• Public roads
• Bike lanes
• Many paved multi-use paths
• Local streets

Trail access can vary depending on the land manager. Some city parks, county open spaces, state parks, and federal lands have different rules regarding e-bike access.

Before heading out, always check posted signs and local regulations for the trail or park you plan to visit.

Helmet Requirements

Colorado only requires helmets by law for Class 3 e-bike riders.

Even when not legally required, we strongly recommend wearing a properly fitted helmet every time you ride.

A helmet is one of the simplest ways to make every ride safer.

Don't Modify Your E-Bike

Changing your e-bike's factory speed or power settings may violate Colorado law and could change how your bike is legally classified.

If you're considering modifications, understand the legal implications before making changes.

Buying an E-Bike? Ask These Questions

Before purchasing, make sure you know:

• What class is the bike?
• What is the motor's rated wattage?
• What is the top assisted speed?
• Where can I legally ride it?

A reputable seller should clearly disclose this information before you buy.
