by

As electric bikes grow in popularity for commuting and recreation, it is important to understand the laws that regulate their use in Washington State. Whether cruising city streets or riding along bike paths, understanding these rules can help riders stay safe and avoid tickets.

Classes of Electric-Assisted Bikes

Washington state law classifies e-bikes into three categories, based on speed and motor type[1]:

  • Class 1: Equipped with a motor that provides assistance only while the rider is pedaling; assistance stops when the bicycle reaches 20 mph
  • Class 2: Equipped with a motor that can propel the bicycle without pedaling; assistance stops when the bicycle reaches 20 mph
  • Class 3: Equipped with a motor that provides assistance only while the rider is pedaling; must be equipped with a speedometer; assistance stops when the bicycle reaches 28 mph

Allowed Riding Zones[2]:

  • Roads & bike lanes: All three classes permitted
  • Shared-use paths: Only Class 1 and Class 2 e-bikes are allowed. Class 3 may be permitted if the path runs adjacent to a highway
  • Sidewalks: Class 1 and 2 e-bikes are generally treated like regular bicycles, but local rules may vary. Class 3 e-bikes are generally prohibited, unless no safe alternative route exists
  • Natural-surface/non-motorized trails: E-bikes of any class are not allowed, unless specifically authorized by a local authority or agency

Equipment Requirements

  • E-bikes must have a permanent label that clearly displays the classification number, top assisted speed, and motor wattage[3]
  • When riding at night, e-bikes must be equipped with a white front light visible from at least 500 feet, and a red rear reflector visible from at least 600 feet[4]
  • While Washington State does not have a helmet law, riders are encouraged to check city or county regulations to ensure compliance[5]

Local Enforcement

Bicyclists who violate traffic laws may receive citations, and parents can face criminal charges if their children operate e-bikes unlawfully[6]. By understanding the laws that govern e-bikes, riders can enjoy while staying safe and compliant on Washington’s roads and paths.
