The Silent Danger: Why E-Bike Accidents Are Surging in Hawaii (And Who Is Liable?)

If you drive through Kaka‘ako, Waikiki, or Ewa Beach, you’ve seen them: electric bikes zipping through traffic, often moving as fast as mopeds but without the noise—or the protection.

While e-bikes are a convenient way to get around our islands, they have contributed to a disturbing spike in serious injuries. In 2025, Hawaii traffic fatalities surpassed the previous year’s totals, with a significant rise in incidents involving "vulnerable road users" like e-bike riders and pedestrians.

Why These Accidents Are Different

As a personal injury attorney, I am seeing a specific pattern in these crashes that makes them legally complex:

1. The "Speed Gap": Drivers often misjudge the speed of an approaching e-bike. A driver might think they have time to make a left turn, not realizing the "bicycle" approaching them is actually traveling at 20+ mph.

2. Catastrophic Injuries: Because e-bike riders are traveling at moped speeds but often wearing only bicycle helmets (or no protection at all), the injuries we see—traumatic brain injuries (TBI), spinal fractures, and severe road rash—are often far worse than standard bicycle accidents.

3. The "insurance Void": This is the biggest trap for victims. Many e-bike riders do not carry insurance, and standard auto insurance policies often deny coverage for "motorized vehicles" that aren't registered.

Who Is Responsible?

If you or your child has been injured on an e-bike, or by an e-bike rider, determining liability is critical.

• Negligent Drivers: If a car turns left in front of an e-bike (the most common accident scenario), the driver is typically at fault. Hawaii's "distracted driving" laws apply heavily here.

• Product Liability: There are cases where e-bike batteries malfunction (causing fires) or where brakes fail at high speeds. In these cases, the manufacturer, not the rider, may be liable.

• Parental Liability: With so many teenagers riding high-powered e-bikes in West Oahu and Honolulu, parents can sometimes be held liable if they knowingly allowed a minor to operate a "modified" bike that exceeds legal speed limits.

Protecting Your Family

The laws regarding e-bikes in Hawaii are still catching up to the technology. Until they do, you must be your own advocate.

• Check Your Uninsured Motorist (UM/UIM) Coverage: This is the single most important thing you can do. If you are hit by an uninsured e-bike rider while walking, your own car insurance might be the only source of recovery—but only if you have high UM/UIM limits.
