Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. A suspension fork, 2x8 drivetrain, and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.
It's right for you if...
You're new to the trail and you’re looking for a real mountain bike that doubles as a commuter—and you want it all at an exceptional value.
The tech you get
A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, 2x8 drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes, and a terrain-smoothing suspension fork with a lockout.
The final word
Marlin 5 is a great ride for all your adventures. But it's also versatile, and Marlin 5 is a popular ride on college campuses because the rack and kickstand mounts make it easy to accessorize and haul a load.
Why you'll love it
- It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus, or just getting from A to B on any surface
- Smaller frame sizes (XXS, XS, and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently
- Marlin models in XXS through S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
- Rack and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
- Like every model in the Marlin family, it's backed by Trek's lifetime warranty
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.
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.
