Overview
E-bikes (electric bicycles) use pedal-assist motors to help riders climb hills and extend range. U.S. e-bike sales grew 145% from 2019-2020, reaching $1.3 billion annually by 2021, transforming bike commuting and sparking trail access debates.
Class Systems
- Class 1: Pedal-assist up to 20 mph (most trail-legal)
- Class 2: Throttle-assist up to 20 mph (moped-style)
- Class 3: Pedal-assist up to 28 mph (commuter bikes)
Classification determined trail access, with many singletrack trails banning Class 2/3 but allowing Class 1.
Trail Access Controversies
Mountain bikers debated whether e-bikes belonged on singletrack. Advocates argued e-bikes democratize trails for older/disabled riders. Critics cited speed differentials, trail erosion, and changing wilderness character.
Pandemic Boom
COVID-19 lockdowns drove e-bike sales up 145% (2020), as people sought car alternatives and outdoor recreation. Supply chain issues caused 6-12 month delivery delays.
