Colorado E-Scooter, E-Bike & Moped Laws (2026 Guide)

I ride an e-bike almost every day. It's how I get to the office, to Broncos games, and to my daughter's school. Before that, I spent years racing mountain bikes, road bikes, BMX, and downhill, and I've ridden motorcycles my whole life. So I've spent a lot of time on every kind of two-wheeler that shares the road with cars, and I know how little room for error you get on any of them.

E-scooters, e-bikes, and mopeds are everywhere in Denver now, and the injuries have followed. What most riders don't realize is that Colorado treats these three very differently. That difference affects where you can ride, whether you need a license or insurance, and whose insurance pays when a driver hits you.

Why this matters right now

Denver recorded eight deaths of standing e-scooter riders in 2025, four times the previous annual record. Seven of those eight involved a collision with a motor vehicle. Police reports only capture a fraction of the injuries. Denver Health alone logged 1,868 patient encounters for scooter injuries in 2025, more than five a day.

E-bike injuries are climbing too. Children's Hospital Colorado reported a 184% increase in e-bike traumatic injuries last year and an 84% increase from e-scooters.

Three different vehicles under Colorado law

Electric scooters. The stand-up kind, rented or owned. Colorado defines an electric scooter as a device under 100 pounds, with handlebars and an electric motor, and a top motor speed of 20 mph on flat pavement. Since 2019, state law has given e-scooter riders the same rights and duties on the road as e-bike riders. No registration or driver's license is required.

Electric bicycles. Colorado recognizes three classes:

• Class 1: pedal assist only, motor stops helping at 20 mph.
• Class 2: has a throttle, motor stops at 20 mph.
• Class 3: pedal assist only, motor stops at 28 mph, and it must have a speedometer. Riders must be at least 16, and riders under 18 must wear a helmet.

Every e-bike sold in Colorado is supposed to carry a label showing its class, top assisted speed, and motor wattage. E-bike riders don't need registration or a license. Class 1 and 2 e-bikes can generally go anywhere a regular bike can, while Class 3 bikes are limited on paths unless the path is part of a street or a local government allows them. Local governments can restrict any class on paths they control.

Mopeds and low-power scooters. The sit-down kind, like a 50cc Vespa-style scooter. Colorado calls these "low-power scooters": no manual clutch, and either 50cc or less or an electric motor of 4,476 watts or less. These are treated like motor vehicles. You need a valid driver's license, the scooter has to be registered (a three-year decal), and you have to carry auto insurance to register it.

The "e-bikes" that aren't e-bikes

This is the biggest area of confusion I see. Many of the electric dirt bikes and throttle-only "e-bikes" being sold, especially to teenagers, go well past 28 mph and don't fit any of Colorado's three e-bike classes. If it isn't a Class 1, 2, or 3 e-bike, the law doesn't treat it like one. Depending on the machine, it may legally be a motorcycle or an off-highway vehicle, with registration, licensing, and insurance consequences that most parents never think about until after a crash.

Where you can ride in Denver

State law sets the baseline, and cities add their own rules on top. Sidewalk rules in particular vary by city and even by neighborhood, so check local ordinances before you assume a sidewalk is fair game. Anywhere you do ride on a sidewalk or crosswalk, state law requires you to yield to pedestrians and give an audible warning before passing.

Denver has also tightened its rules for rentals. As of July 1, 2026, the city's shared e-scooters and e-bikes must use sidewalk detection technology and be parked in designated spots. If a rental starts warning you to get off the sidewalk, that's why.

Who pays when a driver hits you

This is where the vehicle type matters most.

The at-fault driver's liability insurance is the first source, same as any crash. But in Colorado, there's a good chance that driver has no insurance or too little of it. I covered those numbers in What Does "Full Coverage" Mean in Colorado?

Your own UM/UIM coverage can follow you. This surprises many people. In DeHerrera v. Sentry Insurance Co., 30 P.3d 167 (Colo. 2001), the Colorado Supreme Court held that UM/UIM coverage protects the insured person, not a particular vehicle, so an insurer generally can't deny UM/UIM just because you weren't in a car when you were hit. That means the UM/UIM on your car policy may cover you on an e-scooter, an e-bike, or on foot. Insurers still try to write around this with policy language, so don't take a denial at face value.

MedPay is less predictable. Whether your MedPay applies on a scooter or e-bike depends on how your policy defines who and what is covered. Read the policy, or have someone read it for you, before you assume either way. If MedPay isn't available or runs out, here's who pays your medical bills next.

If you ride a moped or low-power scooter, it has its own required policy, and that policy's limits and coverages matter. Mopeds get the same "minimum coverage" treatment as cars, and the same gaps.

If the driver took off, your UM coverage may still apply. Hit-and-run and no-contact crashes have their own rules, which I break down in Hit-and-Run and Phantom Vehicle Claims in Colorado.

Rental scooters and bikes add another layer

When you unlock a rental, you accept a user agreement, and those agreements usually include liability waivers and arbitration clauses. That doesn't mean you have no claim. A driver who hits you is still responsible, and a defective rental (failed brakes, a stem that folds, a throttle that sticks) can create a claim against the company. But it means the paperwork you clicked through matters, so take screenshots of the app, your ride history, and the vehicle's ID number right after a crash.

If a pothole or broken pavement on a city street caused the crash, a different clock applies. Claims against government entities in Colorado generally require written notice within 182 days, much shorter than the normal deadline. I explain how that works in The 182-Day Deadline That Can Kill a Colorado Injury Claim.

What to do after a crash

Get medical care first. Head injuries are common in scooter and e-bike crashes and aren't always obvious right away. Then, if you can:

1. Call the police and get a report number, especially if a car was involved.
2. Photograph the scene, the vehicles, your injuries, and the scooter or bike.
3. Get the driver's name, insurance, and plate number, plus contact info for any witnesses.
4. Look for video from nearby gas stations, parking lots, and storefronts, and ask quickly, because footage gets overwritten.
5. For a rental, screenshot your ride in the app and note the vehicle's ID number.
6. Keep the helmet and damaged gear. Don't repair or throw anything away.

Then check your own auto policy for UM/UIM before you talk to any insurance company.

How I can help

I handle bicycle, e-bike, scooter, and motorcycle crash cases across Colorado, and I ride the same streets my clients do. You can read more about how I approach these cases on my bicycle accident and motorcycle accident pages. If you're a cyclist, Colorado's 3-foot passing law is worth knowing too.

My fee is 29% pre-litigation and 33% if we sue, compared to the 33-35% and 40-45% most Colorado firms charge. You'll have my direct cell number from day one.

Frequently Asked Questions

Do I need a driver's license to ride an e-scooter in Colorado?

No. Colorado exempts electric scooter and e-bike riders from motor vehicle registration and license requirements. Mopeds and low-power scooters are different and do require a license.

Do I need insurance for an e-bike or e-scooter?

Colorado doesn't require it. But your existing auto policy's UM/UIM coverage may protect you if a driver hits you while you're riding, so check it.

Does my car insurance cover me if I'm hit on a scooter?

Your UM/UIM coverage may, because Colorado courts have held that it follows the person rather than the vehicle. Whether MedPay applies depends on your policy's wording.

Is a 50cc moped legal to ride without insurance in Colorado?

No. Low-power scooters, including 50cc mopeds, must be registered, and you have to carry auto insurance to register one. You also need a valid driver's license to ride it.

What if my kid's "e-bike" goes 40 mph?

Then it's probably not an e-bike under Colorado law. Throttle-driven electric bikes that exceed the Class 1, 2, or 3 limits may be treated as motorcycles or off-highway vehicles, which carries registration, licensing, and insurance consequences.
