Tributary is Salsa’s electric rugged-road adventure bike. It’s built to devour big, burly dirt routes. Tributary’s well-balanced gravel geometry, massive tire clearance, and suspension fork mean total comfort and control on sketchy surfaces — even at ebike speeds. The BOSCH Performance Line Speed motor empowers riders to tackle demanding bikepacking routes, explore vast networks of forest roads, or add miles to any adventure. Pair all that with Salsa’s on-bike cargo features, and Tributary is ready to take riders from their front door to far-out.
