Context
How Washington regulates e-bikes
Washington recognizes Class 1, Class 2, and Class 3 e-bikes, but the state definition changes on June 11, 2026. After that date, vehicles that can exceed 20 mph on motor power alone, or that are designed, manufactured, or intended to be easily configured outside e-bike limits, are not treated as electric-assisted bicycles under Washington law.
