Incident Overview

On May 14, 2026, a consumer who had purchased a Ridstar Q30 (model FP4820R0) as a gift reported that the battery failed within a week of use. The consumer assembled the bike, and it ran initially without issue. However, less than a week later, the device owner noticed the battery began to smoke. He removed the battery from the bike, and shortly thereafter it caught fire, burning his wrist.

The battery was completely destroyed in the fire, and the consumer disposed of it properly. The incident was reported to the CPSC via SaferProducts.gov, where it was categorized as a Fire Or Burn Hazard resulting from a Manufacturing Defect. No prior issues with the product were described in the report.

Safety Concerns

Immediate Dangers: Lithium-ion battery failures can lead to thermal runaway, a rapid self-heating reaction that produces intense heat, flames, and toxic gases. In this incident, the battery ignited after smoking, posing an immediate burn risk to anyone nearby. The user sustained a wrist burn from the fire.

Warning Signs: Smoking from the battery preceded the fire. Consumers should be alert for any unusual heat, odor, smoke, or swelling from a battery, as these are often precursors to a catastrophic failure.

Property Damage Potential: A battery fire of this nature can quickly spread to nearby materials, potentially causing significant property damage. The report notes the battery was completely fried, indicating total destruction. Had the fire not been contained, it could have endangered the surrounding area.

Who Might Be Affected: The primary risk is to the device owner and anyone nearby when the failure occurs. In this case, the user was present and was burned. Bystanders, including children or pets, could also be harmed by flames or toxic smoke.
