CO HB1197

Starting January 1, 2027, multiple mode e-bikes must have labels identifying all classes in which they can operate (Class 1, 2, or 3)

Sellers must disclose motor power in watts, maximum speed, e-bike class, and for Class 3 bikes, that riders must be at least 16 years old to operate

Falsely labeling or advertising non-e-bikes as e-bikes constitutes a deceptive trade practice under the Colorado Consumer Protection Act; non-compliant vehicles marketed with e-bike terms must include a specific disclosure stating they are motor vehicles subject to different laws

Lithium-ion batteries for e-bikes must be certified by an accredited testing laboratory for compliance with UL2849, EN15194, or another safety standard approved by the Division of Fire Prevention and Control

Vehicles designed to be easily modified to exceed e-bike speed limits (via switches, software, or apps) are excluded from the legal definition of electrical assisted bicycle
