Incident Overview

On December 1, 2024, a consumer was using a Yosuda L-001S exercise bike when the pedal unexpectedly unscrewed while pedaling. The incident, reported to the CPSC on an unspecified date, resulted in a fall hazard. According to the report filed on SaferProducts.gov (Report ID 5891292), the consumer stated, "When I pedal my exercise bike the pedal unscrewed." No first aid or medical attention was received, as indicated by the severity classification (Severity ID 6).

The incident occurred during normal use of the stationary bike, which is designed for indoor exercise. The pedal detachment created an immediate risk of falling, as the rider lost stability. The consumer did not report any prior issues with the product. The report does not specify whether the bike was recently purchased or how long it had been in use. The defect appears to be a manufacturing issue, as the pedal should remain securely attached during operation.

Safety Concerns

Immediate Dangers: A pedal that unscrews during use can cause the rider to lose balance and fall off the bike, potentially resulting in bruises, sprains, fractures, or head injuries if the rider strikes nearby objects or the floor.

Long-Term Risks: Repeated incidents or near-misses may discourage regular exercise, impacting cardiovascular health. Additionally, if the defect is widespread, it could indicate a systemic quality control issue with the model.

Who Might Be Affected: The primary user of the exercise bike is at risk. Bystanders, such as family members exercising nearby, could also be injured if the rider falls into them.

Warning Signs: A loose or wobbling pedal during use may indicate that the threads are not properly engaged or that the pedal is about to detach. Regular inspection of pedal tightness can help identify potential failure before it occurs.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: Cease use of the Yosuda L-001S exercise bike until the pedal issue is resolved to prevent potential falls and injuries.

Inspect the Pedals: Check both pedals for tightness and signs of wear or damage. If the pedal unscrews easily, do not reattach it without professional evaluation.

Preserve the Product: Keep the bike and any detached parts in their current condition for potential inspection by the manufacturer or a third party. Do not attempt to repair or modify the pedal mechanism yourself.
