Rider-owned mountain bikes and community, built in Bellingham.
Transition Bikes is an independent, rider-owned American company specializing in mountain bikes and an active trail-riding community.
Founded by riders Kevin Menard and Kyle Young, Transition began in the early 2000s by shipping bikes from Kevin’s basement. The owners say that the company has grown while retaining its rider-owned, community-focused approach; its early Bottlerocket helped establish its identity. Transition is headquartered in Bellingham, Washington.
