Please inspect the package upon receipt to make sure all parts are included, and no damage is present.

Please contact Bicycle-Engines.com at (406) 586-5970 to request a damage call tag (DCT). Once a DCT has been issued the item must be returned to the shipping company in the original packaging. If no DCT is issued an (RMA) number may be issued for return of the product to Bicycle-Engines.com for inspection of damages. Once received, if damage is found to be caused by shipping or improper packing, a replacement will be sent free of charge.

All warranty claims may be subject to sending picture or video content of the malfunctioning or broken product. Refusal to send picture or videos of the issue may result in denial of warranty request. In some instances, pictures or videos are required in order to successfully process the warranty claim in our system.

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. Return Merchandise Authorization number (RMA) is required before any warranty claim will be accepted. To initiate a warranty claim call 406-586-5970 or send an email to returns@bicycle-engines.com. The RMA number must be clearly visible on the OUTER SHIPPING BOX, NOT THE ACTUAL PRODUCT BOX. Any packages received without an RMA# will be refused.
