Marin Alpine Trail E (Bosch)- Marins biggest, baddest beast of a bike family!
The Marin Alpine Trail E1 2025 is a high-performance electric mountain bike designed for riders seeking exceptional performance on the most challenging trails. The integration of the latest Bosch drive unit delivers a seamless surge of power, effortlessly conquering steep climbs and technical ascents. The upgraded 750Wh battery ensures ample power for extended rides and ambitious backcountry adventures, allowing riders to focus on the trail ahead without range anxiety.
Marin's commitment to performance is evident in every aspect of the Alpine Trail E 2025. With 170mm of front suspension travel, the bike absorbs impacts with ease, providing confidence-inspiring control and stability. The all-new Series 4 aluminum MultiTrac 2 LT frame further enhances the ride, maximising the performance of the Bosch system and delivering a stiffer, more responsive feel on even the most technical descents. This e-MTB is not just a machine; it's a tool for pushing limits and exploring new horizons.
170MM OF FRONT SUSPENSION
The Alpine Trail E 2025 is built to tame the wildest trails, thanks to its 170mm of front suspension travel. Rocks, roots, and drops become mere playthings as the bike effortlessly absorbs every impact, keeping you in control and pushing your limits.
SERIES 4 ALUMINUM FRAME
Alpine Trail E models are built upon Marins Series 4 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing, giving the rider the highest-end alloy frame that Marin offers, compatible with modern coil or air shocks.
MULTITRAC SUSPENSION
Marin developed the all-new Series 4 aluminum frame in conjunction with the new human-powered Alpine Trail models and notable new features shared between the platforms. Firstly, travel has been increased by 10mm at both ends, now standing at 170mm (f) and 160mm (r), which is also an increase of 10mm beyond the current Shimano-equipped models. MultiTrac 2 LT (“Long Travel,” 150mm+), with rear pivots relocated from the seatstays to chainstays, makes its eMTB debut and delivers the suspension performance and tunability demanded of the longer travel. With MultiTrac 2 LT, the benefits of relocating the rear pivot points from the seatstay to the chainstay become apparent, as it reduces anti-rise, allowing for better chassis control while braking, more mid-stroke support, and better feel at bottom out. Furthermore, relocation of the pivots provides the added benefit of allowing for adjustable chainstay lengths and bottom bracket heights. Ultimately, it’s a better-riding, better-performing suspension system made possible by the new pivot placement.
ADJUSTABLE GEOMETRY
Adjustable geometry features are new to the 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 Marins 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.
MIXED WHEEL SIZES
29” front and 27.5”+ rear wheel sizes are the ideal combination for the Alpine Trail E, with larger front wheel easily rolling over most any trail obstacle and offering the best cornering traction, while the burly 27.5” x 2.8” rear setup adds playfulness and enhances acceleration and braking traction.
PROTECTION
Chainstays and seatstays are protected with durable rubber guards that minimize noise and protect paint finishes. Made from a 30% fiberglass-infused nylon, similar to what is used on safety and football helmets, the moto-inspired integrated downtube guard helps deflect errant rocks, logs, or anything else riders may encounter on the trail. This guard also includes drain ports to let moisture flow from the frame. Cable ports are of an all-new design and keep the frame innards sealed. These ports use rubber membranes punctured during initial assembly and seal around the housing or hose once inserted. Out at the wheels, CushCore inserts enhance tire performance and traction while also protecting the rims on both models.
