Incident Overview

On March 3, 2026, at approximately 6:30 PM, a minor child was riding a Super73-Z Adventure Series SE electric bicycle (serial number F55HY0016, purchased December 27, 2025) in a flat school parking lot in San Marcos, California. The bike was traveling at about 10 mph in stock configuration, with no prior modifications or service. According to the incident report, the front fork lower leg casting suddenly fractured and completely separated from the fork body, causing the rider to lose all steering control and be thrown to the ground. Two witnesses observed the incident.

The reporter, the parent of the child, stated that the bike was only 66 days old at the time of the failure. The detached casting piece has been retained. The reporter noted that Super73 denied the warranty claim, citing unrelated modifications. The report was filed with the CPSC SaferProducts.gov database (Report ID 5938709) as a structural safety defect on a motor-assisted vehicle involving a minor child.

Safety Concerns

Immediate Dangers: The sudden fracture of the front fork lower leg casting eliminates steering control, causing the rider to be thrown forward. At speeds as low as 10 mph, this can result in impact injuries to the head, face, arms, and torso, as well as abrasions from sliding on pavement.

Long-Term Risks: If the casting defect is widespread, continued use of affected bicycles could lead to additional failures. Without a recall or repair, riders remain at risk of sudden loss of control, potentially at higher speeds or in traffic, leading to more severe injuries.

Who Might Be Affected: The primary risk is to the rider, especially minor children who may be less able to anticipate or react to a sudden mechanical failure. Bystanders or others in the vicinity could also be struck if the rider loses control and veers into them.

Warning Signs: The report indicates a catastrophic fracture without prior warning. However, any unusual noises, vibrations, or visible cracks in the fork area should be taken as immediate danger signs. Riders should inspect the front fork lower casting regularly for hairline cracks or deformation.
