Trek Marlin+ 8 2026 - Electric Mountain Bike

The Trek Marlin+ 8 builds on the trusted handling of the Marlin platform and adds intuitive electric assistance for a smoother, more capable ride. The Bosch Active Line Plus motor delivers up to 50Nm of torque, providing steady, quiet support that feels natural, ideal for both first-time e-MTB riders and seasoned trail explorers. With minimal pedal resistance when unpowered, it rides just as smoothly on or off the motor’s assistance.

The integrated 400Wh CompactTube battery keeps weight low and central for balanced handling while offering enough range for long trail sessions or all-day adventures. It’s neatly built into the down tube, preserving the Marlin’s clean, purposeful look.
The Alpha Gold Aluminium frame is designed for strength, precision, and comfort. With modern geometry, Boost148 rear spacing, and internal cable routing, it’s as durable as it is stylish. The RockShox Recon Silver RL Air fork with 120mm of travel smooths out rough terrain, while the lockout feature helps you climb more efficiently on firm surfaces.
Shimano’s Deore 12-speed drivetrain provides a huge 10–51T gear range, making steep climbs easier and descents faster. The system shifts crisply and reliably, even under power, while the FSA crankset adds stiffness and strength to every pedal stroke.
Shimano’s 4-piston MT420 hydraulic brakes deliver strong, controlled stopping power in all conditions, ideal for the added speed and momentum of an e-MTB. Rolling on wide 27.5” Bontrager Line TLR 30 rims and grippy 2.6” Gunnison Pro XR tyres, the Marlin+ 8 offers excellent traction and comfort whether you’re on loose dirt, roots, or rocky trails.
A TranzX dropper post comes fitted as standard, allowing you to quickly adjust saddle height on the fly for technical descents or climbs. With a Bontrager Verse P3 saddle and ergonomic cockpit, you’ll stay comfortable and in control wherever you ride.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
