"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 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.

Sizing

How do you know what size of bike you should buy?

A good place to start is using the sizing charts included for each bike on the info page. If you're in the middle of the recommended height range for a specific size then usually that's the correct one to go with. If you find yourself overlapping sizes at either the top or bottom of the height recommendation than sizing up or down could be a consideration.

For more relaxed fitting "city-style" bikes sizing is less crucial because often they will have adjustable stems and offer more overlap in sizing. Smaller bikes will be slightly easier to manage when starting and stopping while larger bikes will feel more stable when riding. Most often we recommend sizing down in this category.

Bikes that have a more aggressive riding position i.e. road, gravel and mountain bikes sizing is more important. In these categories we usually look closely at 3 numbers, reach, stack, and top-tube length.
