About Trek

The best bike, ridden everywhere.

Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.

Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
