Washington
Last updated
Washington wrote the nation's first modern three-class e-bike law in 2018 and still asks for no license, no registration, and no insurance for Class 1, Class 2, or Class 3. Class 1 gives pedal assist up to 20 mph on a 750-watt maximum motor, Class 2 adds a throttle up to 20 mph, and Class 3 gives pedal assist only up to 28 mph with a speedometer required by statute. All three use highways and bike lanes the same as bicycles.
There is no statewide minimum age for Class 1 or Class 2, while riders under 16 may not operate a Class 3, and Washington sets no statewide helmet law, though several cities and counties impose their own by ordinance. Class 1 and Class 2 ride shared-use paths and sidewalks unless a local jurisdiction restricts them; Class 3 is barred from both except where locally permitted, and natural-surface trails stay closed unless the land manager opens them. As of June 11, 2026, Washington SB 6110 strips e-bike status from any two-wheeler that can exceed 20 mph on motor power alone or that ships with a switch to ride out of class, while the WE-Bike program pays $300 and $1,200 point-of-sale rebates through March 2027. Our Washington bicycle and e-bike insurance page pairs these rules with the state's best rides, riding season, and events. The full breakdown is below.
Washington E-bike Laws
The nation's first modern three-class law, no license, no registration, and a 2026 crackdown on e-motos. Here is where Washington stands on e-bikes.
Washington wrote the nation's first modern three-class e-bike law in 2018 — and just closed its biggest loophole. As of June 11, 2026, Washington SB 6110 strips e-bike status from any two-wheeler that can exceed 20 mph on motor power alone, while compliant Class 1, Class 2, and Class 3 e-bikes keep riding license-free.
The motor assists only while the rider pedals and ceases at 20 mph; 750-watt maximum (RCW 46.04.169).
The motor may propel the bike on its own, with assistance ending at 20 mph.
Pedal assist to 28 mph, speedometer required by statute, and riders must be 16 or older.
No driver license is required to operate an e-bike of any class (RCW 46.20.500).
E-bikes are excluded from motor vehicle registration; bikes exceeding 750 watts or class speed limits fall under moped or motorcycle rules.
Washington's mandatory liability law covers motor vehicles only — e-bike coverage is on you.
Riders under 16 may not operate a Class 3 e-bike (RCW 46.20.500); Class 1 and Class 2 carry no statewide minimum.
Washington has no statewide bicycle helmet law; several cities and counties impose their own by ordinance.
Where You Can Ride
- Roads & bike lanesAll three classes use highways and bike lanes the same as bicycles (RCW 46.61.710).
- Shared-use pathsClass 1 and Class 2 are allowed unless a local jurisdiction restricts them; Class 3 is barred except where locally permitted.
- SidewalksClass 1 and Class 2 ride sidewalks like bicycles subject to local rules; Class 3 is unlawful there unless no alternative exists (RCW 46.61.710).
- Natural-surface trailsClosed to e-bikes unless the land manager opens them (RCW 46.61.710); DNR and State Parks designate e-bike trails individually.
- E-motosAny vehicle exceeding 20 mph on motor power alone, or built to be easily switched out of class, is not a legal e-bike under Washington SB 6110.
The E-Moto Loophole Closes
Washington SB 6110, signed in March 2026, takes effect June 11, 2026: a two-wheeler that can exceed 20 mph on motor power alone, or that ships with a switch to ride out of class, is no longer an e-bike. The law also directs the Department of Licensing to draft a full e-moto framework — registration, fees, minimum ages — with recommendations due to the Legislature by December 15, 2026. Meanwhile the WE-Bike program is paying $300 and $1,200 point-of-sale rebates through March 2027.
Effective June 7, 2018 under Washington SB 6434. Statutes: RCW 46.04.169, 46.61.710, 46.20.500. Cities and park districts can add their own path and trail restrictions — check signage where you ride. Last reviewed June 2026.
