Colorado treats an e-bike as a bicycle, not a motor vehicle: no license, no registration, and no insurance for Class 1, Class 2, or Class 3. Class 1 gives pedal assist up to 20 mph, Class 2 adds a throttle up to 20 mph, and Class 3 gives pedal assist only up to 28 mph with no speedometer requirement in the statute. All three carry full bicycle rights and duties on Colorado roads and in bike lanes, and Colorado is the only state that pays you at the register: a $225 point-of-sale discount on a qualified e-bike, down from $450 through 2025.
There is no statewide minimum age for Class 1 or Class 2, while riders under 16 may not operate a Class 3 but may still ride as passengers; every Class 3 operator and passenger under 18 wears a helmet. Class 1 and Class 2 ride bike paths, sidewalks, and state-park multi-use trails wherever bicycles are authorized, with local opt-out, while Class 3 stays on roads, bike lanes, and park roads unless a local authority permits more. Since August 6, 2025, Colorado HB25-1197 requires lithium-ion battery certification and strips e-bike status from any bike built to be easily switched past its class limits; from January 1, 2027, new e-bikes must be labeled with every class they can operate in. Our Colorado bicycle and e-bike insurance page pairs these rules with the state's best rides, riding season, and events. The full breakdown is below.
Colorado E-bike Laws
Three classes, no license, no registration, and a $225 discount at the register. Here is where Colorado stands on e-bikes and the rules that tightened in 2025.
Colorado treats e-bikes as bicycles, not motor vehicles, and is the only state that pays you at the register: a $225 point-of-sale discount on a qualified e-bike, down from $450 through 2025. The three-class framework dates to Colorado HB17-1151; Colorado HB25-1197 tightened it in 2025 with battery certification and an out-of-class exclusion.
The motor assists only while the rider is pedaling and cuts out at 20 mph (CRS 42-1-102).
The motor assists whether or not the rider pedals, ceasing at 20 mph.
Pedal assist only to 28 mph; Colorado's statute has no speedometer requirement.
An e-bike is excluded from the motor vehicle definition (CRS 42-1-102), so no license for any class.
No state registration or plates for e-bikes that meet the 750-watt, three-class definition.
Mandatory auto insurance does not reach e-bikes — coverage is the rider's choice, and on you.
No statewide minimum for Class 1 or Class 2; riders under 16 may not operate a Class 3 but may ride as passengers (CRS 42-4-1412).
Every Class 3 operator and passenger under 18 wears a CPSC- or ASTM-compliant helmet (CRS 42-4-1412); no statewide helmet law for Class 1 or Class 2.
Where You Can Ride
- Roads & bike lanesAll three classes carry full bicycle rights and duties on Colorado roads (CRS 42-4-1412).
- Bike & pedestrian pathsClass 1 and Class 2 ride wherever bicycles are authorized, with local opt-out; Class 3 is barred unless the path runs within a street or the local authority permits it.
- SidewalksAllowed statewide with pedestrian duties unless a local ordinance prohibits it (CRS 42-4-1412) — Denver and several cities do.
- State parksColorado Parks and Wildlife allows Class 1 and Class 2 on multi-use trails open to bikes; Class 3 stays on park roads and bike lanes.
- Out-of-class & mislabeled e-bikesA bike built to be easily switched past its class limits is not an e-bike under Colorado HB25-1197, and selling one labeled as an e-bike is a deceptive trade practice.
Labels Must Name Every Class
Colorado HB25-1197's second phase takes effect January 1, 2027: new e-bikes must be labeled with the highest class, or each class, they can operate in, and a multiple-mode e-bike must meet the requirements of every class it offers. The seller disclosures, lithium-ion battery certification, and false-labeling ban have applied since August 6, 2025.
Effective August 6, 2025 under Colorado HB25-1197. Statutes: CRS 42-1-102(28.5), 42-1-102(58), 42-4-1412. Cities and park districts can add their own path and trail restrictions — check signage where you ride. Last reviewed June 2026.
