New state law defines difference between e-bikes and electric motorcycles

WHATCOM COUNTY, Wash. — A new statewide law takes effect on June 11, 2026. It modifies the legal definition of electric-assisted bicycles to draw a strict boundary between e-bikes and electric motorcycles.

While individual cities or counties retain the authority to decide where compliant e-bikes can be ridden (such as specific trails and sidewalks), the baseline definition of what physically constitutes a legal e-bike vs. a motor vehicle is now uniform across Washington.

The law targets overpowered, modified, or out-of-compliance electric cycles that have flooded the market, often marketed as “e-bikes” but operating like mopeds or dirt bikes.

To remain legally classified as an e-bike in Washington, a vehicle must utilize a motor of 750 watts or less and fit into the standard 3-class system. The new law explicitly excludes any vehicle that:

Can exceed 20 mph under motor power alone (without pedaling).
Is designed, manufactured, or intended by the seller to be easily configured or unlocked to bypass the standard e-bike class limits.
Does not have fully operative pedals driven by human propulsion.

Any electric cycle that does not meet the e-bike definition is considered an electric motorcycle, which alters its legal and operational rules significantly:

Minimum Age: 16+
Driver’s License: Required
Endorsement: Motorcycle Endorsement Required
Registration & Plates: Required (Must be titled/registered)
Insurance: Mandatory Liability Insurance

While Whatcom County has not issued a formal, dedicated press release regarding the June 11, 2026 state law, local municipalities within the county are actively preparing for it. The City of Ferndale has launched a proactive community education initiative specifically addressing the upcoming changes and the broader issue of high-powered electric cycles.

The City of Ferndale updated its municipal communications to draw a hard line between compliant e-bikes and unregulated electric motorcycles (often called “e-motos”).
Ferndale officials emphasize several key points aligned with the new state reality:

The “Out-of-the-Box” Warning: Ferndale explicitly warns parents that despite how they are marketed, many high-speed electric cycles are not legal for kids and cannot simply be “ridden out of the box” on public streets anymore.
Call 911 for Reckless Riding: The city has advised residents that if they witness someone operating an e-bike or e-motorcycle in an unsafe manner, failing to follow the rules of the road, or riding in prohibited areas (like sidewalks for Class 3 or e-motos), they should call 911 immediately.
Strict Class 3 Enforcement: Ferndale is reiterating that Class 3 e-bikes (which assist up to 28 mph) require the rider to be at least 16 years old and are strictly barred from sidewalks and shared-use paths.

The City of Bellingham and local trail organizations (such as the Whatcom Mountain Bike Coalition) are focusing on trail access and safety. Because the new state law officially strips the “e-bike” label from any modified or out-of-compliance vehicle, Bellingham authorities are using the law to keep heavy, high-speed electric dirt bikes off municipal multi-use paths and natural-surface trail systems (like those at Galbraith Mountain or the Interurban Trail). In Bellingham, Class 1 and Class 2 e-bikes remain legal on most shared-use paths, but anything exceeding those caps is treated as a motorized vehicle and restricted to open roads.

Across Whatcom County, local police departments are signaling that their primary concern heading into the summer is youth safety. Because many popular models used by teenagers can be easily modified via software or a simple wire-snip to exceed 20 mph without pedaling, local police are using the June 11 transition to educate families that these modified bikes now require a driver’s license, a motorcycle endorsement, registration, and insurance.
