All motorized bicycle engine kits and bicycle engine parts come with a 30 day manufacturer warranty and a limited 6 month Bicycle-Engines.com extended warranty. Products damaged by neglect or abuse will not be covered. If your engine kit is found to be defective within the first 6 months of normal use, a replacement or refund will be given at the discretion of Bicycle-Engines.com. The customer is responsible for any applicable postage required to return the defective part.

All warranty returns must be called in or emailed in advance. Replacement parts will be issued for damaged items or manufacturer defects that fall under the warranty time frame.
