Aspirus trauma leaders are seeing a noticeable rise in serious e-bike-related injuries as warmer weather brings more riders outdoors.
Unlike traditional pedal bicycles, e-bikes are heavier, travel at higher speeds and require longer stopping distances, factors that contribute to more severe trauma when crashes occur.
According to the National Institutes of Health, national data shows that a properly fitted helmet can reduce the risk of severe head injury by as much as 85%.
Aspirus trauma coordinator Jamie Armbruster says the most common injuries include fractures, facial and dental trauma, internal organ damage and traumatic brain injuries, many of which are linked to riders not wearing helmets or using helmets that are not designed for e-bike speeds. She notes that recent studies identify two groups at highest risk: children and teens, especially males younger than 16 and adults 45-64.
“E-bikes are not the same as pedal bikes,” Armbruster said. “They’re heavier, they go faster, and they’re less maneuverable. The injuries we see can be life-altering or fatal, especially when riders skip helmets or use ones that aren’t certified for higher speeds.”
Local law enforcement is also seeing increased use of e-bikes and e-motos, electric dirt-bike-style devices that lack pedals and are not legal for use on public roads, sidewalks or multiuse trails. Wausau Police Department Patrol Capt. Melinda Pauls says many riders do not realize that e-motos cannot be registered, lack required safety features and may be subject to citations or impoundment if operated in public areas.
Multiuse trails present additional safety concerns. Pedestrians, including children near parks, may enter paths unexpectedly. Riders are encouraged to slow down, announce when passing and use bells or verbal cues to prevent collisions.
“Safe e-bike riding is just safe bicycle riding,” Pauls said. “Wear a helmet, follow the rules of the road, and know what you’re buying before you ride it. Some devices simply aren’t legal or safe for public use.”
Trauma experts also recommend safety training, understanding local ordinances, avoiding riding under the influence and following manufacturer guidance when charging lithium-ion batteries.
“Many people still view e-bikes the same way they view traditional bicycles,” Armbruster said. “But the speed, weight, and injury patterns tell a different story. Taking a few basic precautions can make the difference between a minor crash and a life-changing injury.”
Trauma specialists say helmet use remains the single most effective step riders can take to reduce the risk of serious injury.
