February 24, 2026 — A Hiboy S2/S2Pro electric scooter incident has resulted in a child sustaining a severe ankle laceration requiring three stitches. The injury occurred when the scooter’s rear disc brake, described as an exposed sharp metal disc, sliced the child’s ankle as the electric motor engaged. The incident highlights a potential design flaw concerning exposed moving parts on the popular electric scooter model.
Product Details
Incident Overview
The incident occurred when a child was operating a Hiboy Electric Scooter, specifically the S2/S2Pro model, while attempting to ascend an uphill incline. To initiate the electric motor function, which requires a minimum speed of 3 MPH, the child was manually pushing the scooter forward with their left foot. As the electric motor engaged and provided propulsion, the sudden force caused the child’s left ankle to come into contact with the scooter’s rear disc brake. The report details that the sharp metal disc of the brake sliced the child’s left ankle, necessitating three stitches for the injury. The parent noted that the design of the scooter leaves this sharp metal disc openly exposed at the bottom, creating a hazard for such injuries. Although the child was wearing both shoes and socks at the time, which likely prevented an even more severe injury, the incident underscores the danger posed by the exposed component.
Safety Concerns
This incident reveals significant safety concerns related to the design of the Hiboy S2/S2Pro electric scooter:
- Immediate Dangers: The primary immediate danger is the risk of severe lacerations, deep cuts, and puncture wounds from contact with the exposed, sharp metal disc brake. Such injuries can lead to significant blood loss, requiring immediate medical attention and stitches. Depending on the depth and location of the cut, there is also a risk of damaging tendons, ligaments, nerves, or blood vessels, which could have serious short-term and long-term consequences.
- Long-Term Risks: Beyond the immediate injury, potential long-term risks include permanent scarring, chronic pain, reduced mobility or flexibility in the affected limb, and in cases of nerve damage, persistent numbness or weakness. There is also a risk of infection in the wound if not properly treated, which could lead to further complications.
- Who Might Be Affected: Scooter users, particularly children or those unfamiliar with the specific mechanics of electric scooter engagement and propulsion, are most at risk. The incident specifically involved a child, highlighting the vulnerability of younger users who may not fully understand or anticipate the sudden engagement of the motor or the proximity of their feet to moving components. Anyone whose foot might inadvertently come into contact with the exposed brake assembly during operation or even while mounting/dismounting the scooter could be affected.
- Property Damage Potential: This specific incident primarily concerns personal injury. While a severe crash *caused by* such an injury might indirectly lead to property damage, the direct mechanism of the brake cutting the ankle does not typically pose a risk of property damage.
What Consumers Should Do
Consumers who own or use a Hiboy S2/S2Pro electric scooter should take the following actions:
- Immediate Steps: If you or someone you know has sustained an injury from the Hiboy S2/S2Pro scooter, seek medical attention immediately. Discontinue use of the affected scooter and keep it in its current condition for potential inspection.
- How to Check Your Product: Verify if you own a Hiboy S2 or S2Pro electric scooter. Visually inspect the rear wheel area, specifically the disc brake assembly, to determine if the sharp metal disc is openly exposed and accessible, especially from the bottom where a foot could contact it.
- Prevention Measures:
- Exercise extreme caution when operating the scooter, particularly during initial acceleration or when the electric motor engages.
- Always wear appropriate protective footwear that fully covers the foot and ankle. While the incident noted shoes and socks were worn, additional ankle protection might be considered given the design flaw.
- Avoid placing feet near the rear wheel or any moving parts while the scooter is in operation, especially during the initial push-off phase to engage the motor.
- Familiarize yourself and any users (especially children) with the scooter’s operation and potential hazards.
- Reporting Procedures: If you or someone you know has experienced a similar incident or a near-miss with a Hiboy S2/S2Pro electric scooter, please report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report is crucial for tracking potential hazards and prompting further action.
