SB 6110 Washington Senate · 2025-2026 Regular Session

Addressing electric-assisted bicycles and electric motorcycles.

SB 6110 defines three classes of electric-assisted bicycles (e-bikes) in Washington State, setting speed limits (20 mph for Classes 1 and 2, 28 mph for Class 3) and requiring a 750-watt motor limit. It explicitly excludes vehicles that can exceed 20 mph on electric power alone. The bill also creates a work group tasked with studying regulatory frameworks for electric motorcycles (a category currently lacking state rules), focusing on definitions, registration, licensing, safety rules, and consumer disclosures. The work group must submit recommendations by December 2027. This legislation establishes definitions for e-bikes and initiates a study process for electric motorcycles, directly affecting riders, manufacturers, and future regulatory development.

MODERATE

The bill was amended to expand its scope by adding a new section that addresses electric motorcycles, which were previously excluded from the act. The legislature now formally recognizes the need to regulate these vehicles and has directed the Department of Licensing to form a work group to study them. The work group's mandate was significantly expanded to include specific topics like civil infractions for juveniles and penalties for adults providing motorcycles to minors, and the timeline for reporting was accelerated to include an interim report by December 2026.

The bill's scope expanded from solely addressing electric-assisted bicycles to explicitly including electric motorcycles, requiring a new regulatory framework to be developed for them.
