About Transition
Transition Bikes started in 2001 when Kevin Menard and Kyle Young quit their telecom jobs and built bicycles out of a Seattle basement. The first complete bike, the Dirtbag, shipped in 2003, and in 2005 the pair moved the company to Bellingham, Washington, to sit next to the steep Pacific Northwest trails they wanted to ride.
The brand stayed rider-owned and gravity-leaning while most peers optimized for cross-country weight. Transition’s Speed Balanced Geometry (SBG) pairs a longer front-center with a shorter fork offset and a steeper seat angle, a setup the company argues keeps the front wheel planted on steep terrain without making the bike feel long everywhere else.
Today Transition builds a full mountain range in carbon and alloy: the short-travel Spur and Smuggler, the all-mountain Sentinel and Scout, the enduro Patrol and Spire, and the TR11 downhill race bike. It also runs two e-MTBs, the lightweight Fazua-powered Relay and the full-power Repeater, both built around the same SBG handling. The company stays privately held in Bellingham.
Most popular Transition models
Transition’s mountain lineup runs the full travel spectrum, all sharing SBG geometry and offered in both carbon and aluminum. The 120mm Spur is the cross-country and down-country bike; the Smuggler and Scout sit in the short-to-mid trail range; the Sentinel is the do-everything all-mountain 29er; and the Patrol and Spire climb into enduro territory at 160mm and 170mm of travel. The TR11 is the dedicated downhill race bike, with more than 200mm of travel for bike parks and World Cup tracks.
The Relay and Repeater carry SBG into the e-MTB category. The Relay is the lightweight option, hiding a Fazua Ride 60 motor in a trail-bike package, while the Repeater is the full-power SRAM Eagle Powertrain enduro bike for big days and bigger descents. A carbon Transition build runs from roughly $3,500 well past $11,000, the kind of replacement value a homeowner’s policy usually caps below, which is where stand-alone electric bike insurance from Velosurance fills the gap.

Transition's Warranty: What It Covers and Where It Stops
Transition backs its frames with a lifetime warranty for the original owner and a separate support program for damage. Five terms decide what that is worth to you.
Lifetime frame warranty for the original owner
Transition frames in the possession of their original owner are covered by a lifetime warranty. It covers defects in materials and workmanship for the useful life of the product.
Registration takes a serial number and proof of purchase
Riders must register their product on Transition's site by providing the serial number and proof of purchase. Claims in the United States or Canada are submitted through an account on the same site.
Secondhand owners keep rider support
All Transition frames fall under the Unlimited Rider Support program, whether you are the original or a secondhand owner. The lifetime warranty itself belongs to the original owner.
Labor and cosmetic damage are not covered
The lifetime warranty does not cover labor costs associated with warranty repairs or replacements. It also excludes normal wear and tear, cosmetic damage including paint aging or fading, and modifications from the original configuration.
Defects only: other damage gets a discount, not coverage
The lifetime warranty covers defects in materials and workmanship. Damage, regardless of how it happened, goes through Unlimited Rider Support, which provides discounted replacement frame parts or repair assistance. Those are the losses a Velosurance policy is built for.
Summary of the Transition Bikes Warranty and Rider Support, reviewed September 17, 2026. Applies to Transition frames in the possession of their original owner. Transition handles claims in the United States and Canada directly, and its international distributors handle claims elsewhere. The manufacturer decides every warranty claim, and its full published terms govern.
