E-Bike Accidents in Colorado: Who Pays?

Short answer: if you were hurt on an e-bike in Colorado, who pays depends mostly on two things. The first is whether what you were riding is legally an e-bike at all. The second is who or what caused the crash: a driver, another rider, or the road itself. The answer changes which insurance is in play and how long you have to act.

E-bikes have made a lot of Colorado commutes better, and they have also put more people at 20 or 28 miles an hour in bike lanes and on roads that were not built for it. Here is how the law sorts out a crash.

Step One: Is It Legally an E-Bike?

Colorado law recognizes three classes of electric-assisted bicycles. All of them have working pedals and a motor of 750 watts or less (C.R.S. § 42-1-102).

Class	How the motor helps	Motor stops assisting at
Class 1	Only while you pedal	20 mph
Class 2	With or without pedaling (throttle)	20 mph
Class 3	Only while you pedal; must have a speedometer	28 mph

Every legal e-bike is supposed to carry a label showing its class, top assisted speed, and motor wattage. That label matters after a crash, so photograph it.

A machine with a motor over 750 watts is not an e-bike under Colorado law, no matter what the box or the website called it. Higher-powered electric bikes fall into scooter or motorcycle territory, which can mean a license, registration, and insurance requirement. Colorado tightened the labeling and marketing rules in 2025 (HB25-1197), and the Attorney General has warned retailers about selling higher-powered machines as e-bikes. If the bike in your crash was really an e-motorcycle, the insurance picture is different, and that is worth sorting out early.

If a Driver Hit You While You Were Riding

On a legal e-bike you have the same rights and duties on the road as the driver of any other vehicle (C.R.S. § 42-4-1412(1)). The fault rules are the same ones that apply to any bicycle crash: passing distance, right-of-way, turning across your path. Our guide to Colorado bicycle laws walks through them.

The first place the money comes from is usually the driver's auto liability insurance. Colorado's minimum is $25,000 per person for bodily injury (more on Colorado's insurance requirements). For a serious injury, that minimum can run out quickly.

That is where your own auto policy can come in, even though you were on a bike and not in a car. Depending on how your policy is written, coverage such as medical payments coverage or uninsured and underinsured motorist coverage may follow you as a cyclist. It is one of the most overlooked sources of recovery for people hurt on bikes. Read the policy, or have a lawyer read it, before assuming it does not apply.

The deadline: a claim against a driver who hit you is a motor vehicle claim, so Colorado generally gives you three years to file suit (C.R.S. § 13-80-101(1)(n)). The fact that you were on a bike does not change that.

If You Were Hit by Someone on an E-Bike

This is the harder one. Legal e-bike riders are exempt from motor vehicle registration and licensing, and an e-bike is not insured like a car. If an e-bike rider hits you while you are walking or riding, there is often no auto policy behind them.

Recovery can still be possible. Depending on the policy language, a rider's homeowner's or renter's liability coverage may respond, though some policies exclude motorized vehicles, and how that applies to an e-bike depends on the wording. If the rider was on an over-750-watt machine that legally needed insurance, that changes things too.

Because it is not always clear which deadline applies to these claims, do not assume you have three years. Treat two years as the outside limit and talk to a lawyer early.

If the Road Caused the Crash

Potholes, missing signage, debris, and badly designed bike lanes cause their share of e-bike crashes. When a city, county, or state agency maintains that road, a strict deadline applies: under Colorado's Governmental Immunity Act, you generally have to file a written notice of claim within 182 days of discovering the injury (C.R.S. § 24-10-109(1)). Miss it and the claim can be lost. Our post on notice of claim deadlines for government entities explains how it works.

A road-condition claim generally runs on Colorado's two-year deadline for injury claims (C.R.S. § 13-80-102(1)(a)), and the 182-day notice comes on top of that, not instead of it.

Helmets, Age Limits, and Kids on E-Bikes

Colorado has no statewide helmet requirement for adults on Class 1 or Class 2 e-bikes. Class 3 is different: anyone under 18 riding or carried on a Class 3 e-bike must wear a properly fastened helmet, and no one under 16 may operate a Class 3 e-bike (C.R.S. § 42-4-1412(15)).

One point surprises people: the same statute says a violation of the Class 3 helmet rule "does not constitute negligence or negligence per se" (C.R.S. § 42-4-1412(15)(c)). Not wearing a helmet does not, by itself, make the crash your fault.

What to Do After an E-Bike Crash

• Call the police and get a report. It locks in names, insurance information, and what everyone said.
• Get medical care, even if you feel mostly fine. Head and wrist injuries are common in e-bike crashes, and some take days to show up.
• Photograph the e-bike's class label, the scene, the bike, your gear, and your injuries.
• Keep the bike as it is. Do not repair or sell it until you know whether its condition matters to the claim.
• Get witness names and phone numbers before people leave.
• Talk to a lawyer before giving a recorded statement to any insurance company.

Frequently Asked Questions

Do I need insurance to ride an e-bike in Colorado?

Colorado does not require registration or a license for a legal e-bike, and e-bikes are not insured like cars. Higher-powered machines that fall outside the e-bike classes can carry license, registration, and insurance requirements.

Will my car insurance cover me if I'm hit while riding my e-bike?

It may. Depending on your policy, medical payments or uninsured and underinsured motorist coverage can apply to you as a cyclist. Check the policy wording, or have a lawyer check it.

How long do I have to file a claim after an e-bike accident in Colorado?

If a driver hit you, generally three years. Other e-bike injury claims may run on a two-year deadline. If a government entity is involved, a 182-day notice of claim applies as well.

Does not wearing a helmet hurt my case?

For Class 3 riders under 18, Colorado's statute says breaking the helmet rule is not negligence or negligence per se. For everyone else there is no statewide helmet requirement for Class 1 or Class 2 e-bikes.

Is a 1,000-watt e-bike legal in Colorado?

Not as an e-bike. Colorado's e-bike classes stop at 750 watts. A more powerful machine falls into a different category, with different rules and insurance requirements.
