I believe she would have more risk than a typical bicycle rental business because she has to assume the liability for both the rental business and the product.

If the bicycles I use for my business have defective brakes and are recalled by the manufacturer, my rental customers are at risk but some of that liability is shouldered by the manufacturer. If bikes I manufacture have defective brakes, I have to assume that liability and could be found at greater fault because I have the ability to test and recall the product.
