Description
Marin Electric: Alpine Trail E2 Bosch - 2024
The all-new Marin Alpine Trail E2 Bosch represents our pinnacle in eMTB capability. Building upon the success of the Alpine Trail E series, these bikes feature Series 4 aluminum MultiTrac 2 LT frames with enhanced durability and performance upgrades, ideal for riders tackling the most challenging terrain. With increased travel to 170mm (front) and 160mm (rear), and pivot relocation to the chainstays, our suspension design offers unparalleled stability and adjustability. Bosch's Performance Line CX drive units deliver 85Nm of torque, powered by a 750Wh PowerTube battery, ensuring extended range for epic adventures. The Alpine Trail E2 (Bosch) is equipped with top-tier Fox suspension, Shimano XT 12-speed drivetrain, and Marin's own CNC 35mm stem and Trail Bar combo, setting a new standard in trail riding excellence. Available at Bike Attack Santa Monica, Playa Vista, Culver City, Los Angeles.
The all-new Alpine Trail E Bosch is our biggest, baddest 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 E2 (Bosch) lights the wick with a premium Fox suspension pairing and Shimano's XT 12-speed drivetrain, along with our own proprietary CNC 35mm stem and Trail Bar combo.

GEOMETRY
We’ve brought adjustable geometry features to the new Alpine Trail E Bosch models—integrated chainstay flip chips and an adjustable headset yield six possible configurations to suit a variety of trails best. Flip chips are easy to reconfigure trailside and are quickly changed using a 6mm hex wrench. They require no additional parts and incorporate laser-etched graphics that indicate the position of the chips. Furthermore, the flip chips located at the seatstay pivots alter the bottom bracket height and chainstay length (low BB/long CS setting = 347/443mm, high BB/short CS setting = 352/435mm) so that riders can perfectly dial their bike in to match the terrain they are looking to conquer. Finally, using our proprietary headset cups and inserts, the headtube angle can be adjusted to +0.75° or -0.75° from the standard 63° position, giving the rider three options to best suit their preferences.
