Trek Marlin+ 6

Marlin+ 6 is an electric mountain bike that's ready to power up your trail rides without breaking the bank. It's equipped with the same fun and confident geometry as the non-electric Marlin, with the added boost of Bosch's Active Line Plus drive system. A 120mm suspension fork soaks up rocks, roots, and potholes on your ride, while 9-speed Shimano CUES is durable and reliable for wherever you roll.

• Its AUTO mode adaptive motor support recognizes speed reductions and adjusts assistance automatically
• The 120mm suspension keeps your ride feeling smooth through bumps, roots, and rough stuff
• Marlin+ is easy to use with simple controls and intuitive support, so you can focus on the ride ahead, not complicated remotes
• Trail-savvy geometry keeps handling easy and confident from singletrack to city streets
• Tons of rack and fender mounts let you customize your ride for the trail or taking on daily commutes

Smooth, quiet support

Bosch Active Line Plus mid-power motor doles out a smooth 50Nm of torque. Its controlled acceleration, low pedal resistance, and super quiet operation give you a natural-feeling, unobtrusive ride.

Clean, simple controls

The 2-in-1 remote and display provides all the information and control you'll need in a compact, full-color handlebar controller with intuitive contols.

System safety taken seriously

Trek sets its e-bike safety standards high with UL certified e-systems, sophisticated battery management failsafe systems and battery cells from tier 1 suppliers.

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Shimano CUES

Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette, and chainrings.
