Silent hazards: the rising danger of e-bikes to everyday pedestrians

Traditional bicycles are predictable. Pedestrians hear them, see them, and generally have time to move. E-bikes operate in near silence at speeds that can exceed 28 miles per hour, giving pedestrians little to no warning before impact.

The rapid spread of electric bicycles across urban sidewalks, crosswalks, and shared paths has changed the pedestrian experience in ways that municipal regulations have not fully caught up with. For walkers, the physical consequences of an e-bike collision are significantly more serious than those from a traditional bicycle crash.

The physics of impact

A traditional bicycle powered by human effort typically travels between 10 and 12 miles per hour. E-bikes, using electric motors, can sustain speeds between 20 and 28 miles per hour depending on the class of the device. Because kinetic energy increases with the square of velocity, an e-bike traveling at top speed delivers substantially more force on impact than a standard bicycle.

High-velocity collisions between e-bikes and pedestrians commonly result in:

• Traumatic brain injuries and skull fractures
• Complex orthopedic fractures, particularly to the hips, pelvis, and lower extremities
• Spinal cord trauma that can cause temporary or permanent loss of function

These injury profiles are closer to those seen in low-speed motor vehicle collisions than standard bicycle accidents.

The element of surprise

Traditional motor vehicles generate engine noise that gives pedestrians a fraction of a second to react. E-bikes produce almost no sound. On a shared path or sidewalk, a rider approaching from behind at 25 miles per hour may be less than a second away at the moment a pedestrian becomes aware of their presence.

This is particularly dangerous for children, older adults, and individuals with visual or auditory impairments, who may have no opportunity to move out of the way before impact occurs.

The legal landscape after an e-bike crash in Illinois

In Illinois, e-bikes are classified into three categories under the Illinois Vehicle Code, with each class subject to different rules about where the device may be operated and what speed limits apply. Class 1 and Class 2 e-bikes are limited to 20 mph motor assistance, while Class 3 devices can reach 28 mph. Where a collision occurs, and what class of e-bike was involved, directly affects which traffic laws apply and who may bear liability.

The Illinois Department of Transportation (IDOT) provides guidance on the use of e-bikes on public paths and roadways across the state, and local municipal rules can add an additional layer of regulation depending on where the crash occurred.

Standard automobile insurance policies generally do not cover e-bike accidents, and homeowners or renters insurance policies may exclude vehicles with alternative power sources from their liability coverage. Identifying the applicable insurance and the responsible party requires a careful review of the specific facts and local regulations. A personal injury attorney familiar with Illinois traffic law can evaluate the circumstances of a crash and help an injured pedestrian understand their options for pursuing compensation.
