Motorized Bicycles in Colorado

There are many benefits to be had by using a motorized bicycle as your primary (or secondary) method of transportation. With rising gas prices, environmental concerns and a suffering economy, it's no wonder more and more people are choosing them over other options.

Like most states, Colorado distinguishes between motorized bicycles, mopeds and motorcycles based on their engine size.

While there are federal laws for e-bikes, Colorado also has its own laws.

Electric Bicycles (E-Bikes)

In Colorado, e-bikes are classified into three categories based on their power output and top assisted speed:

1. Class 1 e-bikes: These bikes have a pedal-assist system and a top assisted speed of 20 mph. They are considered bicycles and can be used on bike lanes, trails, and roads.
2. Class 2 e-bikes: These bikes have a throttle-assist system and a top assisted speed of 20 mph. They are considered bicycles and can be used on bike lanes, trails, and roads.
3. Class 3 e-bikes: These bikes have a pedal-assist system and a top assisted speed of 28 mph. They are considered bicycles, but they can only be used on roads, not on bike lanes or trails.

In Colorado, e-bike riders are subject to the same laws and regulations as traditional bicycle riders. This includes using lights and reflectors at night and following traffic laws. Additionally, riders under 18 years of age are required to wear a helmet.

It's important to note that local regulations may vary, so it's always best to check with your local authorities for more information.

Mopeds

In order for a vehicle to be considered a moped in Colorado it must have an engine size of 50 CC or less, or 4,476 watts for electrical motors.

The majority of scooters will also fall into this category. Although, if you are not careful your vehicle may cross the line and might actually be considered a motorcycle, which has different requirements.

Moped Requirements

In order to drive a moped or scooter, you must have a valid drivers license. You must also need to register your motor-assisted cycle.

Luckily, registration procedure is relatively simple. All you will need is the following:

• A completed and signed Low-Powered Scooter Registration Application (form DR 2701).
• A proof of ownership, such as a bill of sale, affidavit of ownership, or MSO (Manufacturer's Statement of Origin).
• Some proof of insurance.
• A one-time payment of $5.85.

You will need to either mail in all of the required materials, or take them to an authorized moped dealer in your area.

To register by mail, send all of the required materials to the following address:

Colorado Department of Revenue
Motor Vehicle Registration
Denver, CO 80261

You must carry a proof of insurance at all times when riding a motor-assisted cycle in Colorado.
