Trek Marlin 4 Gen 3 Mountain Bike
The Trek Marlin 4 Gen 3 is a versatile hardtail mountain bike that’s equally at home exploring local trails, riding bike paths or getting around town.
Built around Trek’s lightweight Alpha Silver Aluminium frame, the Marlin 4 combines confident mountain bike handling with practical features that make it a great first mountain bike or everyday all-rounder.
A 100mm SR Suntour suspension fork helps smooth out bumps and rough tracks, while the simple 1x8 Shimano drivetrain gives you a useful range of gears without the complication of a front derailleur. Hydraulic disc brakes provide reliable stopping power in both wet and dry conditions.
The Gen 3 Marlin frame also features modern trail-focused geometry and internal routing for a future dropper post upgrade, giving you a bike that can grow with your riding.
