2026 Marin Alpine Trail E2 - Grey Black
MarinThe Alpine Trail E Bosch is our biggest, baddest beast of a bike family, with 170mm of suspension up front, 160mm of MultiTrac 2 travel at the rear and a Bosch CX drive unit at its core, the Alpine Trail E is constructed for riders who challenge themselves with the steepest, most technical terrain, and maximum range for big days in the mountains.
Our MultiTrac 2 LT suspension design has the pivots located on the chainstays to deliver the suspension performance and tunability demanded on our longer travel bikes. Riders also have the ability to alter the head tube angle by +/- .75° by repositioning the lower headset cup while the bottom bracket height/chainstay length can be changed by the means of seatstay flip chips.
Bosch's Performance Line CX drive units twist out 85Nm of torque and are backed by large capacity 750Wh PowerTube batteries, nestled safely in the frame's downtube, giving you the largest battery in the Marin range for the biggest adventures.
The Alpine Trail E2 Bosch lights the wick with a premium Fox suspension pairing and Shimano's XT 12-speed drivetrain, powerful TRP DHR EVO brakes along with our own proprietary CNC 35mm stem and Trail Bar combo.
