Enduro Geometry with Maximum Adjustability

Built around Marin’s robust Series 4 aluminum MultiTrac 2 LT frame, the Alpine Trail E1 features a balanced 170mm front and 160mm rear travel. What sets it apart is its extreme adjustability:

• Flip-Chip Settings: Customize chainstay length and bottom bracket height to match your riding style or wheel configuration.
• Mullet Wheel Setup: Equipped with a 29” front for rollover and a 27.5” rear for agility and strength.

Bosch Performance Line CX Power & Range

The heart of this e-MTB is the Bosch Performance Line CX motor, producing a massive 85Nm of torque and 600W of peak power. To keep you riding longer, it features a 750Wh PowerTube battery, offering an exceptional estimated range of up to 78 miles (125km), making it the perfect partner for all-day alpine adventures.

Durable, Gravity-Focused Components

Every part on the Alpine Trail E1 is selected for durability. The Marzocchi Z1 fork and Marzocchi CR coil rear shock provide a plush, controlled ride on rough descents. Shifting is handled by the e-bike-specific Shimano CUES 10-speed drivetrain, designed for longevity under high torque, while TRP Slate EVO 4-piston brakes ensure you have the stopping power to stay in control.
