1 Year Warranty

The 1 year manufacturer's warranty states that, for JUPITERBIKE Electric Bikes, parts, and components, if the product fails in normal use (with no "customer-induced failure" and no customer changes or modifications to the product) within the first year of ownership, then we will refund or replace it (at our option) at no charge to you except for your cost of shipping it to us. International orders must pay shipping, handling, and any import or export-related expenses for both directions of the shipment. For most U.S. orders, there are no shipping charges for the shipment of the replacement to the customer on warranted product, if ground shipping is selected. JupiterBike v.2 and DLX models are covered by a 90-day manufacturer's warranty instead of 1 year. All other aspects of the warranty are the same except for the length.
