Preventing Tragedy: Knowing the Critical Differences Between E-Bikes and E-Motorcycles

Preventing Tragedy: Knowing the Critical Differences Between E-Bikes and E-Motorcycles

Public safety and local law enforcement agencies have recently raised concerns over a sharp rise in serious collisions involving electric bikes (e-bikes) and motorcycles (e-motos). The U.S. Consumer Product Safety Commission, for example, documented 310 e-bike fatalities from 2017 through 2024 PDF. In response, the U.S. Fire Administration urges parents, consumers and members of the fire service to learn the critical differences between traditional bicycles, e-bikes and e-motos before an emergency occurs. This includes understanding their distinct speeds, weights, legal classifications and emergency response hazards.

Many e-bikes and e-motos are built to look like traditional bicycles, sometimes even featuring nonfunctional pedals to bypass local laws. However, these vehicles operate at speeds and power levels far exceeding legal e-bike limits, creating severe safety risks on public roads, sidewalks and community paths. Most municipalities prohibit the use of e-motos in bike lanes and on multiuse trails, yet many riders — frequently unlicensed minors — operate them illegally. In some cases, serious crashes have led to fatal injuries and parents facing felony charges for child endangerment.

E-bikes are categorized into 3 classes based on how the motor provides power and the speed at which that assistance stops.

• Class 1, pedal-assist only: The motor helps only while the rider is pedaling and cuts off at 20 mph.
• Class 2, throttle-on-demand: The motor can propel the bike entirely on its own (without pedaling) but cuts off at 20 mph.
• Class 3, high-speed pedal-assist: The motor helps only while the rider is pedaling and cuts off at 28 mph.

What parents and consumers should do

If you own, ride or are considering purchasing a motorized two-wheeler, take time now to verify its legal classification and safety requirements.

• Check the motor wattage and top speed.
  Legal e-bikes (Classes 1-3) are capped at a maximum of 750 watts of motor power and a top speed of 28 mph. If the vehicle's motor or maximum speed exceeds these values, it is legally a motorcycle (or e-moto) regardless of whether it has pedals.
• Locate the pedals versus footpegs.
  Legal e-bikes require fully functional, operable bicycle pedals for propulsion. If the vehicle features fixed motorcycle-style footpegs instead of pedals, it is classified as an e-moto, motorcycle or moped.
• Verify licensing and registration requirements.
  Whether a rider of an e-bike is required to possess a license varies by location and by the class of the e-bike, so become familiar with the local rules and regulations. Many states do not require a driver's license, Department of Motor Vehicles (DMV) registration or license plates for Class 1 and 2 e-bikes but do for Class 3. E-motos operated on public streets must be registered with the DMV; equipped with Department of Transportation (DOT)-approved lights, mirrors and turn signals; and operated by a rider with a valid motorcycle license and possibly insurance.
• Obey local path and trail restrictions.
  Class 1, 2 and 3 e-bikes are often permitted on designated bike paths and trails, whereas e-motos are strictly prohibited from these areas and must only be operated on public streets (if street-legal).
• Enforce helmet laws and age limits.
  Although helmets are always recommended for all bicycle riders, local helmet requirements vary by location. Many state laws require riders of Class 3 e-bikes to be at least 16 years old and to wear a helmet. E-motos require full motorcycle safety gear, including DOT-compliant helmets.

What fire departments and emergency responders should know

Fire departments and emergency responders should include e-bike and e-moto safety hazards in training and incident scene planning.

• Add e-bike and e-moto identification to training.
  Training should cover how to quickly differentiate a lightweight e-bike (under 80 lbs.) from a heavy, high-performance e-moto (up to 180+ lbs.). Responders should expect injuries consistent with high-velocity motorcycle accidents at e-moto crash scenes.
• Recognize high-voltage battery hazards.
  While standard e-bikes typically utilize low-voltage 36V to 48V batteries, high-performance e-motos run on larger 60V to 72V+ lithium-ion battery packs. Treat damaged e-moto drivetrains as active high-voltage hazards.
• Avoid cutting electrical components during extrication.
  When stabilizing or extricating a patient from a severely damaged e-moto, personnel must avoid cutting through wrapped wiring harnesses, high-voltage lines or battery enclosures to prevent severe electrical shock or short circuits.
• Prepare for advanced lithium-ion thermal runaway.
  The large-capacity battery packs on e-motos present a higher risk of intense, longer-duration thermal runaway in the event of a fire. Responders should follow established department guidelines for managing large battery fires. Remain aware of all damaged batteries as potential ignition and fire hazards because they can experience thermal runaway and reignition behaviors. Be mindful of responding to incidents involving a battery fire in enclosed spaces. Always don't appropriate personal protective equipment and a self-contained breathing apparatus.
• Educate the community on safety risks.
  During public safety and outreach events, departments should educate families on the legal and physical differences between e-bikes and e-motos. The key message is simple: High-power e-motos do not belong in bike lanes, on sidewalks or in the hands of unlicensed minors on public streets.

In addition, messaging should include guidance on how and where to safely charge e-bikes and e-motos. Ensuring that appropriate and certified charging equipment is used and that batteries are not left unattended while charging, located along the path of emergency egress travel, or exposed to severe weather or temperature conditions are all important messages to emphasize.
