Incident Overview

On April 1, 2026, a consumer and their spouse were using the Umay L20 treadmill they had ordered from Amazon. During the workout, the device delivered multiple electric shocks to both individuals throughout a single use session. The reporter indicated that the shocks occurred repeatedly while the treadmill was operating normally.

According to the incident report filed with the CPSC (Report ID 5986993), the shocks were not a one-time event but happened multiple times, suggesting an ongoing electrical fault. The reporter did not mention any prior issues with the treadmill before this incident. The severity was classified as no first aid or medical attention received, meaning the shocks did not require immediate medical treatment. The exact mechanism of the electrical fault has not been publicly detailed by the manufacturer.

Safety Concerns

Immediate Dangers: Electric shock from a treadmill can cause muscle contractions, loss of balance, and falls, which may lead to serious injuries such as fractures or head trauma. The severity of the shock depends on the current path and duration; even low-voltage shocks can be dangerous if the user has a heart condition or is standing on a wet surface.

Long-Term Risks: Repeated exposure to electric shocks, even those not requiring medical attention, can cause nerve damage, cardiac arrhythmias, or psychological trauma such as fear of using exercise equipment. Chronic exposure to low-level electrical current may also lead to skin burns or tissue damage over time.

Who Might Be Affected: The primary users—adults operating the treadmill—are at direct risk. However, the electrical fault could also pose a hazard to bystanders who touch the equipment or the user during a shock. Children or pets near the treadmill may be more vulnerable due to lower body resistance.

Environmental Triggers: Factors such as high humidity, sweat from the user, or improper grounding of the treadmill can exacerbate the risk of electric shock. The presence of a metal frame or uninsulated components may create a path to ground, increasing the likelihood of a completed circuit through the user's body.
