E-bike versus e-motorcycle classification:

Washington State law defines an e-bike as a bicycle with two or three wheels, a saddle, fully operative pedals for human propulsion, and an electric motor with power of no more than seven hundred fifty watts.   E-motorcycles differ from e-bikes in that the power is greater than 750 watts (often up to 6,000-8,000 watts).  Another key distinction is that e-motorcycles typically do not have operative pedals and instead have stationary foot pegs.  Even
if equipped with a pedal kit or speed regulator, the size of the motor places them outside the e-bicycle classes.

Where and how can e-motorcycles operate?

Traditional motorcycles require lights, turn signals, mirrors, a license plate, and an operator with a motorcycle license (endorsement) to be legally operated on the road.  Therefore, e-motorcycles without all the required road components are only allowed on private property or at recreational parks that allow similar vehicles such as dirt bikes.  If all the road components are available, the e-motorcycle must be registered with the Washington State Department of Licensing and the operator must be at least 16 years of age.

Can I ride them in the roadway?

To ride an E-Motorcycle on a public roadway, the following criteria must be met.

• Vehicle must be issued a license plate and be equipped with a headlight, brake lamp, turn signals, and mirrors.
• The operator must have a driver's license with a motorcycle endorsement, insurance coverage for the motorcycle, and a DOT approved helmet. 

Enforcement

If you observe unlawful e-bike or e-motorcycle behavior, you should call 911 or the non-emergency police number at (206) 296-3311 to report the incident. For incidents not in-progress, please utilize the MySammamish app or online portal or call the non-emergency police number at (206) 296-3311.

Future Work:

The City is continuing to analyze bicycle policies and facility needs through updates to various plans and policies.  These include the Bicycle and Pedestrian Plan (update underway), the Transportation Master Plan update (Fall 2025 kickoff), the municipal code and bicycle facility standard design details (Summer 2025 kickoff).    Please visit the project pages for more information on these projects.
