Troopers warn e-bike riders against modifications

(COLO) – Whether seeking more speed, power or comfort, modifications for e-bikes can reduce the safety components of your e-device, void the manufacturer’s warranty and make your device illegal to ride in certain communities.

“While modifications can frequently lead to component failure, the biggest concern for the community is the safety risk,” stated Col. Mathew C. Packard, chief of the Colorado State Patrol. “Altering a bike past class definitions can come with different legal requirements; for example, you might now have a motorcycle.”

Modifying your e-bike to exceed legal e-bike speed limits (28 mph) or motor limits (750W in the US) may legally reclassify your e-bike as a moped or motorcycle. Under Colorado law, this means you are now required to register and insure the vehicle with the Department of Motor Vehicles. In addition, Colorado has a minimum age of 16 for motorcycles, and all riders are required to have a motorcycle endorsement on their license.

In addition to modifying speed and power, some riders are removing bicycle chains to ride more like a motorcycle and removing safety switches that cut motor power when the brakes are applied.

“Parents of young riders need to understand that this isn’t harmless and should get familiar with the components of their child's e-bikes so they can see when something is different,” stated Col. Packard. “Keep the conversation going about safe riding and making changes to the bike. Teens often want to customize their bikes, but modifications should be made by a professional.”

The Colorado State Patrol is raising awareness of the risks and requirements associated with micromobility devices. Riders and caregivers should know the rules and local ordinances of where they ride to ensure they are operating both legally and safely. Don’t be an e-DIOT, be safe, and be seen as a responsible e-device rider.
