With today's technology, the fastest way to file a warranty claim is to take a digital photo of your bike & broken part and email it to us at firstname.lastname@example.org. Please include your name, address, phone number, model number, date code, date & place of purchase with a brief description of the incident. We'll review your photos and see if we can determine the cause or nature of the problem. If we can, we'll make a decision on your claim. If we can't tell from the photos, then we'll ask you to send the affected part in. Please refer to your owner's manual for complete details on filing a warranty claim.
