Engrossed Substitute Senate Bill 6110 changes Washington law by amending RCW 46.04.169 (the definition of "electric-assisted bicycle"), adding a new section to chapter 46.08 RCW and creating additional new sections. The bill passed the House on March 4, 2026 (Yeas 91, Nays 3) and the Senate on March 10, 2026 (Yeas 44, Nays 4), and was first read February 2, 2026. The act includes an emergency clause that makes Section 3 effective immediately. The amendment to RCW 46.04.169 defines "electric-assisted bicycle" as a twoor three-wheeled bicycle with a saddle, fully operative pedals, and an electric motor of no more than 750 watts, and it establishes three classes: Class 1 (motor assists only when pedaling and stops assisting at 20 mph), Class 2 (motor may be used exclusively to propel the bicycle and cannot provide assistance at 20 mph), and Class 3 (motor assists only when pedaling and stops assisting at 28 mph, and the bicycle must have a speedometer). The definition expressly excludes any vehicle capable of exceeding 20 mph on motor power alone and any vehicle designed or intended by the manufacturer or seller to be easily reconfigured so it does not meet the electric-assisted bicycle requirements. The bill creates a procedural requirement: the Department of Licensing must convene a work group to study and recommend a revised statutory framework for electric motorcycles and may contract with a third-party consultant to support the work. The work group must include specified state agencies, local government and tribal representatives, nonprofit and stakeholder organizations, and at least one nonprofit motorcycle organization or rider. The work group must deliver an interim report with recommendations and draft legislation on definitions and classification by December 15, 2026, and a final report with recommendations and draft legislation by October 31, 2027, to the governor and the Legislature’s transportation committees. The extracted material does not include the full text defining "electric motorcycle," does not specify the exact placement of the new section in chapter 46.08 RCW, and does not state whether any other sections besides Section 3 take effect immediately.

If enacted, the law immediately tightens the state definition of electric-assisted bicycles to a 750-watt motor limit, three distinct class rules tied to pedal-assist and top speeds, and excludes any vehicle that can exceed 20 mph on motor power alone or that is made to be easily reconfigured to evade those limits. It also requires the Department of Licensing to lead a multi-stakeholder work group (including transportation agencies, law enforcement, city and county reps, tribal and nonprofit groups, and motorcycle interests), with authority to hire a third-party consultant, to draft recommended statutory changes for electric motorcycles and report interim recommendations by December 15, 2026 and final recommendations by October 31, 2027; one section of the act takes effect immediately, but the text here does not say which section that is. Practically, the Department of Licensing will take on new coordination and likely contracting costs and staff time to run the study and produce draft legislation, and other listed agencies and organizations will need to commit time and resources to participate. Manufacturers, sellers, and riders of electric bikes will likely see a narrower set of machines qualify as “electric-assisted bicycles,” which can change what products can be marketed or used where and how they’re regulated or enforced; the bill points to potential downstream changes for electric motorcycles and juvenile adjudication processes but leaves key definitions and the exact placement and immediate effects of the new provisions unspecified.
