Electric bikes are becoming a more common sight on Fairfax County trails and neighborhoods, the county announced on May 28. E-bikes offer battery-assisted travel that can help riders climb hills, carry groceries, and take longer trips with less effort. Officials say these bikes are also helping to reduce short car trips that contribute to local congestion.
Virginia law divides e-bikes into three classes: Class 1 (pedal-assist only, up to 20 mph), Class 2 (throttle available, up to 20 mph), and Class 3 (pedal-assist up to 28 mph). For Class 3 bikes, riders must be at least 14 years old and wear a helmet; motors must not exceed 750 watts. No driver’s license or registration is required for any class.
E-bikes are generally permitted wherever traditional bicycles can go unless signs indicate otherwise. Riders should stop before entering streets, use hand signals when safe, yield to pedestrians with an audible signal when passing, follow posted trail rules, and use crosswalks carefully.
Drivers are encountering e-bikes more frequently as their popularity grows. The county reminds drivers that they must stop for cyclists in crosswalks just as they would for pedestrians. E-bikes may travel faster than traditional bicycles—especially downhill or on straightaways—so drivers should give extra space when turning or passing and check blind spots carefully. Virginia law requires at least three feet of space when passing any bicycle or e-bike.
In parks, e-bike riders must observe established hours of operation and posted signage like all visitors. The Park Authority cannot regulate the use of these devices within parks by law; concerns about unsafe operation should be reported to the Police Department at 703-691-2131.
With increased numbers of e-bikes in homes comes greater emphasis on battery safety. The county recommends using chargers made for each device, avoiding overnight charging or leaving batteries unattended while charging, unplugging once fully charged, charging only one device at a time, and keeping batteries away from extreme temperatures.
The Department of Transportation has added 260 e-bikes over the past three years to the Capital Bikeshare system—about 17 percent of its fleet—but these account for nearly half of all trips.
