AB-1557: New Rules for Electric Bicycles

This law lowers the speed limit and power requirements for Class 1 and Class 2 electric bicycles, creates a new category for cargo bikes with higher power limits, bans sales of non-compliant devices with civil fines, and restricts riders under age 16 from using motors stronger than 250 watts.

What This Bill Does

  • Changes the definition of Class 1 and Class 2 electric bicycles so their motor assistance stops at 16 miles per hour instead of 20 miles per hour.
  • Allows cargo electric bicycles to have a motor with up to 750 watts of continuous power if they are built with a reinforced frame and integrated rack or platform for carrying goods or people.
  • Prohibits manufacturers from equipping, and retailers from selling or advertising, devices labeled as Class 1 or Class 2 e-bikes that exceed 250 watts of continuous power or go faster than 16 miles per hour.
  • Sets civil penalties up to $15,000 for a first violation and $50,000 for later violations if sellers break the new motor rules, enforceable by state or local attorneys.
  • Bans people under age 16 from riding any electric bicycle with a motor stronger than 250 watts of continuous power.

Who It Names or Affects

  • Manufacturers and retailers who sell or advertise electric bicycles
  • Riders younger than 16 years old
  • Owners of cargo electric bicycles
