Design and Frame Details of the MY21 Marin Alpine Trail E2 eMTB
The MY21 Marin Alpine Trail E2 eMTB features a Series 4 aluminum frame with robust forgings and manipulated tubing for strength without excess weight. It shares the MultiTrac linkage-driven single-pivot suspension from Marin’s non-electric Alpine Trail, delivering 150mm of rear travel that’s progressive and efficient.
A standout choice is the mullet wheel configuration—29-inch front for rollover capability and a 27.5-inch rear for playful handling and agility in tight turns. The frame integrates the Shimano battery seamlessly into the downtube, with protective guards on the chainstay and motor area to shield against rocks and debris.
Geometry is modern and aggressive: a slack 63-degree head angle for stability on steeps, a steep 78-degree seat tube for efficient climbing, and size-specific reach (e.g., 485mm on large). Chainstays are a nimble 435mm, contributing to the bike’s lively feel. Available in sizes S-XL and a single gray colorway, it’s built for riders who prioritize fun on technical terrain.
