An Onewheel injury claim requires proving three things: the product was defective, the defect caused your injury, and you suffered actual damages. Evidence like the device itself, medical records, expert analysis, and proof connecting the defect to the crash all play a role in building that case.
Across U.S. jurisdictions, defective product injury claims require proof of three elements. The product must have been defective when it left the manufacturer, the defect must have caused the injury, and actual damages must have followed.
Medical records establish the existence and severity of injuries, which are required to prove damages. Documentation may include emergency room records, imaging such as CT scans and MRIs, surgical reports, treatment history, and long-term prognosis. This evidence connects your injuries directly to the crash and demonstrates the financial and physical impact.
Keeping the actual board intact is often necessary to show how the defect occurred. Physical examination can expose problems like sudden shutdown, sensor failure, or imbalance, and courts regularly use the product itself as direct proof of a defect.
To satisfy the causation element, plaintiffs must show that the defect directly caused the injury, rather than rider error or outside factors. Courts need proof that the injury would not have occurred but for the defect or that the defect was a substantial factor in causing harm.
Experts, including engineers and safety specialists, analyze how the Onewheel failed, whether it met safety standards, and whether a safer alternative design existed. Expert testimony is frequently needed to help a jury understand the technical aspects of defects and causation that aren't within everyday experience.
Evidence that the rider was operating the Onewheel as intended or in a reasonably foreseeable manner is critical to the claim. Riding within normal speed ranges and adhering to manufacturer instructions both factor into this. Misuse can significantly weaken or defeat injury claims because liability doesn't attach to injuries caused by unintended or abnormal use.
