"The Alpine Trail E (Bosch) is our biggest, badest beast of a bike family. Moving one step beyond in capability from the Alpine Trail E models, the new Alpine Trial E Bosch eMTBs are constructed with all-new Series 4 aluminum MultiTrac 2 LT frames that feature significant upgrades for riders who challenge themselves with the steepest, most technical terrain, as well as those who require the maximum in range." We've increased the travel by 10mm at both ends, now standing at 170mm (f) and 160mm (r), and relocated the pivots to the chainstays to deliver the suspension performance and tunability demanded by the longer travel. Riders 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 E1 Bosch is smartly spec'd with choice Marzocchi suspension with a coil shock out back, Shimano's innovative CUES 10-speed drivetrain and Tektro's Slate EVO 4-piston brakes with 203mm x 2.3mm rotors for when you need to reel in the party.
