Product Info

Zipping through town, dipping your toes into the trail for the first time, or slicing through switchbacks, no matter where you roll, Marlin is a confidence-inspiring hardtail that’s ready for anything. With versatile trail geometry and Smart Wheel Sizing, this hardtail MTB is built to tackle everything. There’s a good reason it’s the world’s favorite TrekMarlin 4 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. It features a trail-savvy frame with a suspension fork, 8-speed Shimano ESSA shifting, and mounts for a rack and kickstand that make it an ideal choice for trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.


Will my bike have a curved top tube?

    Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.


Fit for every rider

    Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.


High tech, high value

    Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.
