WARRANTY AND RIDER SUPPORT

At Transition Bikes, we take pride in building products designed to handle the ever-increasing demands of modern mountain biking. From the world-renowned terrain right in our PNW backyard, to the sport's biggest stages across the globe, our bikes are meant to be ridden hard by riders pushing the limits of what a mountain bike can do. The mission of our Rider Support Team is simple: Keep our riders riding when things go sideways. Transition Bikes offers real, human support via phone, live chats, and email between the hours of 9am and 5pm PST, Monday through Friday. Whether you're the original owner, purchased your Transition secondhand, or picked one up from your local dealer's demo fleet, we are committed to finding you a fair and timely solution.

UNLIMITED RIDER SUPPORT

ALL Transition frames are covered by our Unlimited Rider Support program. This program keeps you riding by providing discounted replacement frame parts or repair assistance in the event of damage - regardless of how it happened, or whether you're the original or a secondhand owner. If we are unable to replace or repair your frame part, we will work with you to find a suitable solution.

LIFETIME WARRANTY

The PBJ Alloy, released in 2025, is covered for life against manufacturing defects. This policy applies to original owners only. Lifetime Warranty covers defects in materials and workmanship for the useful life of the product. Riders must register their product on our site by providing the serial number and proof of purchase. Our lifetime warranty does not cover normal wear-and-tear, failures caused by lack of maintenance, cosmetic damage including paint aging or fading, paint damage caused by the installation or removal of frame protection or adhesives, modifications from the original configuration, or labor costs associated with warranty repairs or replacements.

In the event of an issue with your frame, Transition Bikes will determine whether it qualifies as a ‘Warranty Issue’ or is covered under our ‘Unlimited Rider Support’ (see below for details).

In the event that you have to send back all or part of your frame under warranty, you are responsible for the shipping costs to get it to us, and we will pay the return shipping.

WE GET IT, PEOPLE WHO RIDE OUR BIKES RIDE HARD

Above is our official stance, since to some degree these things need to be spelled out. Our entire philosophy is based around being a rider-owned company, and we take that seriously. We're well aware that not every circumstance can be accounted for and not every case falls neatly into one of the above categories. We look at every warranty and rider support case with a fresh lens, and treat every situation in the manner in which we would expect it to be handled. Our goal is to leave no rider who supports us without support in return.

*We strive for consistency, and our aim is to provide identical, color-matching replacement parts wherever possible. Depending on availability, variations in paint batches, and paint fading slightly with age, a replacement part may come in a slightly different shade, or in some cases, a different color altogether. These differences are cosmetic only, and do not affect the performance of your bike.
