Smooth, quiet support
Bosch Active Line Plus mid-power motor doles out a smooth 50 Nm 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-colour handlebar controller with intuitive controls.
System safety taken seriously
Trek sets its e-bike safety standards high with UL certified e-systems, sophisticated battery management fail-safe systems and battery cells from tier 1 suppliers.
Ride more and smile more with PowerMore
Want to ride farther? Add PowerMore to your Marlin+. This booster battery extends your range, so you get more supported ride time.
Shimano Deore
Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
Adaptive assist
Automatically adjusting motor support recognises speed reductions and adjusts assistance level accordingly so you can spend more time riding and less time adjusting assistance levels.
Ready to customise
Customise your Marlin+ for your life with mounts for a rack, mudguard and kickstand, so you're ready for everything from trail tackling or cruising to class.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.
