Limited Warranty

  •  Your purchase includes the following limited warranty, which is in lieu of all other express warranties. This warranty is extended only to the initial consumer purchaser. This warranty gives you specific legal rights. You may have other legal rights that vary from state to state. Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on how long implied warranties last, so the above limitations or exclusions may not apply to you.

Frame Warranty

  • Steel frames are guaranteed against manufacturing defects (defined as a defect in materials or workmanship as delivered with the product) for (90) days from the date of original purchase, subject to the terms and conditions of this limited warranty. If frame failure should occur due to faulty materials or workmanship during the guarantee period, the frame will be replaced with the same or most nearly compatible frame then available. For frame replacement under the limited warranty, please contact the authorized dealer the bicycle was purchased from. Authorized dealers will contact us to initiate a warranty claim on your behalf. However, frames must be returned for inspection at the customer’s expense and include a copy of the original and dated purchasing receipt. International customers who purchase a bicycle from outside their home country are responsible for shipping to AND from Sunday USA. Please note: the fork is not part of the frame.

Component Warranty

  • Most non-proprietary components have a limited warranty offered by the component manufacturer directly. Please contact your authorized dealer for additional information on making a warranty claim on such a part. All other parts except Normal Wear Parts are guaranteed against a defect in materials or workmanship for a period of (90) days from the date of original purchase, subject to the terms and conditions of this limited warranty. If failure of a part should occur during the warranty period, the part will be replaced. Please contact an authorized dealer to initiate a warranty claim on your behalf. All parts must be returned for inspection at the customer’s expense and be accompanied by a copy of the original and dated proof of purchase. International customers who purchase a bicycle from outside their home country are responsible for shipping to AND from Sunday USA. Normal Wear Parts, defined as grips, tubes, tires, cables, brake shoes and saddle covering have a thirty (30) day limited warranty. Claims against Normal Wear parts and missing parts must be made within thirty (30) days of purchase. Please contact your local authorized dealer warranty assistance on components.


  • Any other warranty claim not included in the statements above is void. This especially includes installation, assembly and disassembly costs. The limited warranty does not cover paint damage, rust, any modification made to the bicycle, normal wear and tear, improper assembly or maintenance and installation of parts or accessories not originally intended or compatible with the bicycle as sold. The warranty does not apply to damage or failure due to accident, abuse, misuse, neglect or theft. Claims involving these issues will not be honored.

Useful Lifecycle 

  • The length of useful lifecycle will vary depending on the type of bike, riding conditions and care the bicycle receives. Competition, jumping, downhill racing, trick riding, trial riding, riding in severe conditions or climates, riding with heavy loads or any other non-standard use can substantially shorten the useful product lifecycle and is not recommended. Any one or a combination of these conditions may result in an unpredictable failure that is not covered by this limited warranty. All bicycles and frame sets should be periodically checked by an authorized dealer for indications of potential problems, impropriate use and/or abuse. These are important safety checks and may help prevent accidents, bodily injury to the rider and a shortened product cycle.
