Incident Overview

According to the incident report filed on May 2, 2026, the consumer's 13-year-old daughter was riding the Ridstar FP4825RO e-bike when she applied the brake and it failed to stop the bike. The child reported that the tires then flew off the bike, causing her to be thrown from the vehicle. The incident resulted in large bruises on the child's legs and arms, though no broken bones were sustained, and no medical attention was sought.

The consumer, who purchased the bike from Ridster.net, stated that she considered the bike extremely unsafe and believed it should be reported. The report did not indicate any prior issues with the bike or whether the product was new at the time of the incident. The reporter retained the bike but did not provide details about the condition of the tires or brake system before the failure. The incident highlights a potential manufacturing defect that could lead to catastrophic loss of control.

Safety Concerns

Immediate Dangers: When a brake fails and tires detach simultaneously, the rider loses all ability to slow down or steer. This can result in high-speed falls or collisions with obstacles, pedestrians, or vehicles, leading to traumatic injuries such as fractures, head trauma, or road rash.

Who Might Be Affected: The primary victims are riders, especially children or inexperienced users who may not have the strength or reflexes to compensate for a sudden mechanical failure. Bystanders and property near the path of an uncontrolled e-bike are also at risk.

Environmental Triggers: Factors such as high speed, downhill slopes, or wet roads can exacerbate the danger of brake failure and tire detachment. Even a minor defect in the wheel attachment mechanism can become critical under the stress of braking or turning.

Warning Signs: Potential precursors include unusual vibrations from the wheels, wobbling, or a feeling of looseness in the handlebars. Brake performance may degrade gradually, such as requiring increased lever travel or making grinding noises. Any such symptoms warrant immediate inspection.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If your Ridstar FP4825RO or similar e-bike shows any signs of brake or wheel issues, cease riding it at once. Riding with compromised brakes or wheels can lead to serious injury.

Do Not Attempt Repairs: Do not try to fix the brake system or wheel attachment yourself unless you are a qualified technician. Improper repairs may worsen the defect and void any warranty.

Preserve the Product: Keep the e-bike in its current condition, including any detached parts. Do not modify or dispose of it, as it may be needed for investigation by the CPSC or for potential legal claims.

Document the Incident: Take photographs of the bike, especially the brake components and wheel attachment points. Write down details such as the date, time, location, and sequence of events while they are fresh in your memory.

Report to the CPSC: File a report on SaferProducts.gov with the incident report number 6045875 for reference. This helps regulators track safety issues and may lead to a recall.

Check for Recalls: Visit CPSC.gov to see if there are any recalls for the Ridstar FP4825RO or other Ridstar models. Even if no recall exists, your report could prompt one.

If you or your child suffered injury or property damage from this e-bike, you may want to speak with a product liability attorney about your legal options.
