12 News reported that two people were critically injured in an e-bike crash in north Phoenix near 43rd Avenue and Cactus Road on the night of Oct. 30. No determination of fault has been reported, and nothing below should be read as a conclusion about who or what caused the collision.
In Arizona, an electric bicycle that meets the statutory definition is treated as a bicycle rather than a motor vehicle, which means a rider hurt on one generally has the same rights as any other cyclist on the roadway. A claim turns on proving that another party failed to use reasonable care: a driver who turned across a rider's path, a motorist who passed closer than the three feet required by A.R.S. § 28-735, a property owner who left a hazard in a bike lane, or a manufacturer whose battery, brakes, or frame failed. Arizona uses pure comparative fault under A.R.S. § 12-2505, so a rider found partly responsible still recovers, reduced by that percentage; an insurer's early blame-shifting is an argument, not a ruling. Most injury suits must be filed within two years under A.R.S. § 12-542, and a claim against a city, county, or state defendant requires written notice within 180 days under A.R.S. § 12-821.01.
Who Can Be Responsible When an E-Bike Rider Is Hurt
Liability is not limited to another vehicle. Depending on what an investigation shows, responsibility can rest with a motorist, with a government entity that designed or maintained a roadway or signal, with a private property owner, with a contractor whose work left debris or an unmarked lane obstruction, or with the company that manufactured, assembled, or sold the e-bike or its battery. Product claims matter here because e-bike components can fail at speed, and the physical evidence that proves it is in the bike itself.
Preserve the bike. Do not let a repair shop, an insurer, or a landlord dispose of it, and do not have it fixed. Photograph the frame, wheels, brakes, battery housing, and any damage before it is moved again. Keep the helmet, the clothing, and any mount, light, or camera that was on the bike.
If a driver involved in an injury collision leaves the scene, A.R.S. § 28-661 imposes a duty to stop and remain. A departed driver does not end a claim; uninsured motorist coverage on a household auto policy can apply to a bicyclist struck by a vehicle, even though the rider was not in a car.
What to Do While Someone Is Still Hospitalized
Critical injuries mean the injured person cannot gather evidence, so someone else has to. Request the police report number and the crash report as soon as it is available. Ask nearby businesses and residences about exterior camera footage within days; most systems overwrite within one to two weeks. Write down the names and phone numbers of anyone who stopped at the scene.
Keep every medical record and bill, including ambulance and air transport invoices. Track who is paying what; health insurance, MedPay, and hospital liens all interact, and the hospital's billed charge is often not the number that governs a later reimbursement claim.
Give no recorded statement to the other side's insurer while a family member is in intensive care. You are not obligated to, and early statements made without the medical picture are routinely used to argue that injuries are minor or that the rider contributed to the crash.
Deadlines That Quietly End Claims
Two years from the date of injury is the general filing deadline under A.R.S. § 12-542. If any potential defendant is a public entity or public employee, a written notice of claim must be served within 180 days of when the claim accrues under A.R.S. § 12-821.01, and a suit against that entity carries a shorter one-year filing period. Six months passes fast when a family is managing surgeries and rehabilitation, so identify early whether a city, county, or state entity could be involved.
If an injured person does not survive, Arizona separates the claims: A.R.S. § 12-611 through A.R.S. § 12-613 govern wrongful death brought by statutory beneficiaries, and A.R.S. § 14-3110 governs the survival action the estate brings for losses the person sustained before death.
