Peloton could be sued under product liability law depending on the State law where the injury occurred. These laws differ from jurisdiction to jurisdiction but typically provide injured people legal recourse for a dangerous product. The machine is required to meet the ordinary expectations of the consumer. As such, if the machine has a defect or is dangerous, it does not meet the consumers expectation. Other parties besides Peloton could also be liable for the injuries for the defective machine. For example, if there is a manufacturing defect, the manufacturer could be held liable. In that case, strict liability would apply.

Product liability refers to either a manufacturer or seller being found liable for placing a defective product into the stream of commerce. Peloton, as the seller of the treadmill, could be held liable as part of the distribution change. There is no federal product liability law. These claims are based on state laws and brought under can be brought under additional theories of negligence, strict liability, and breach of warranty. There are also State commercial statutes that may apply. As to product defects, the victim would usually have to prove that the machine was defective and that the defect made the product unreasonably safe. The defect maybe by design, manufacturing, or marketing.

As to defenses, Peloton might argue that the victim misused or altered the machine, or did not heed the warnings. These cases are quite complex and expensive. Proving the case will require experts. In addition, each state has its own set of laws requiring an experienced personal injury attorney to assist the victim.
