Electric Bikes Can Be Fast and Dangerous. Here’s How to Stay Safe
During a quiet evening stroll in her Minnesota neighborhood, Janet Stotko was struck by a 14-year-old boy riding an electric bike at approximately 25 mph. The collision left her unconscious and bleeding on the sidewalk, requiring urgent medical attention. Though the 2024 incident nearly claimed her life, Stotko survived after suffering severe brain injuries, a facial fracture, and a broken eardrum. Following weeks of hospitalization and brain surgery, she now advocates for tighter e-bike regulations to prevent similar accidents.
While electric bikes provide an eco-friendly, affordable alternative to cars, their rising popularity has raised safety alarms. A report from the University of California, San Francisco, revealed that e-bike-related rider injuries increased by nearly 100% annually between 2017 and 2022. In San Diego, injuries among riders under 18 jumped by 300% from 2019 to 2023, according to another study from the University of California, San Diego.
Understanding E-Bike Classifications
Most e-bikes are classified under federal law as nonmotorized vehicles, akin to conventional bicycles. This means riders typically don’t need a license, insurance, or a helmet. However, many states have implemented stricter rules, with varying guidelines across regions. For example, Connecticut recently passed legislation mandating helmets for all e-bike riders and requiring a driver’s license for bikes with motors exceeding 750 watts.
States often categorize e-bikes into three main types: – **Class 1** e-bikes activate motors only when the rider pedals, reaching a top speed of 20 mph. – **Class 2** models use throttles to achieve the 20 mph limit without pedaling. – **Class 3** bikes offer pedal-assist up to 28 mph. Faster versions, sometimes labeled as e-motos, can exceed 40 mph even without pedaling. These high-speed bikes are treated like motorcycles in many states, prohibiting their use on sidewalks and shared paths.
“Increased speeds directly correlate with greater injury severity,” said John Maa, a general surgeon at MarinHealth Medical Center. “Newton’s principles show that force and kinetic energy rise exponentially with velocity.”
Regulations are evolving rapidly, creating confusion for riders. For instance, New York City set a 15 mph speed limit for all e-bikes in October, while Florida proposed a bill restricting speeds to 10 mph near pedestrians. In contrast, some states lack specific rules for ultra-fast e-bikes, leaving them in legal gray areas.
Manufacturers often obscure the distinction between standard e-bikes and high-speed models. To ensure safety, riders should verify a bike’s maximum speed, motor power, and whether it requires pedaling. These details determine if the vehicle falls under motor vehicle laws, which could restrict its use on certain paths.
Charles DiMaggio, an injury researcher at New York University, advises riders to “read the manual, watch instructional videos, and review their specific model’s features.” Visiting a local bike shop before purchasing can help clarify rules and test the bike’s performance. Health organizations, including the American College of Surgeons, stress that helmets are essential, alongside defensive riding practices like using lights and maintaining awareness of surroundings.
As e-bike technology advances, so must safety awareness. Staying informed about local regulations and understanding a vehicle’s capabilities can reduce risks for both riders and pedestrians. The goal is to ensure that these convenient tools remain a safe addition to urban mobility.
