Attorney General Phil Weiser issues public advisory on e-bike regulations

Oct. 12, 2026 (DENVER) - Attorney General Phil Weiser has issued a public advisory alerting Coloradans of the state's e-bike consumer regulations, and the dangers of treating high-powered, electric vehicles as e-bikes. The advisory follows the passage of HB25-1197, which became law in August of 2025.

"Retailers need to clearly explain what they're selling," said Attorney General Phil Weiser. "When you buy a product, you should know exactly what you're getting. That means knowing how fast a vehicle can go, how powerful it is, and whether it qualifies as an e-bike. This information is especially important for parents choosing a bike for their child."

Electronic scooters and bicycles - often marketed simply as "e-bikes" - have become extremely popular throughout the state. Last year, Colorado enacted HB25-1197 (opens new tab) which clarifies labeling and marketing requirements of electrical assisted bicycles. These vehicles must fall into one of three categories if they are going to be marketed as an electrical assisted bicycle or similar. These include:

• Class 1: E-bikes with a pedal-assisted motor that assists to 20 miles per hour.
• Class 2: E-bikes with an electric motor that assists to 20 miles per hour.
• Class 3: E-bikes with a pedal-assisted motor that assists to 28 miles per hour and a speedometer.

As more Coloradans buy e-bikes for themselves or their children, properly labeling and marketing these products is paramount to safety. If an online retailer markets a product as an "e-bike," but sells an electric vehicle that does not match any of these class requirements and does not contain other mandatory disclosures, this is a violation of the Colorado Consumer Protection Act and potentially puts consumers in harm's way. When an electric vehicle has a motor that is more powerful than 750 watts, it is no longer an e-bike, and can be especially dangerous for teens or children to operate. While selling vehicles of this caliber is not per se illegal, marketing them as e-bikes without the proper disclaimers or limitations is a violation of state consumer protection laws.
