Marlin – hardtail mountain bikes for all riders

Loved the world over, the Marlin has long held the hearts of new riders and seasoned rippers alike, and to keep everyone rolling with ear-to-ear grins we’ve revamped it with more trail confidence than ever. Whether zipping through town, dipping your toes into the trail for the first time or slicing through switchbacks as a well-seasoned rider, you’ll appreciate the sleek new frame that ups the capability and brings looks to match. There’s a reason why it’s always been your favourite.

Total trail confidence

A bike's geometry is the defining framework it's built on, and the Marlin is a true mountain bike at it's core. Its measurements are perfectly dialled to give you a confidence-inspiring, planted feel when you’re rolling down steep and bumpy trails, while keeping it easy to pedal back to the top when you’re ready for another lap.


Marlin’s head tube (a) sits at a slacker (more acute) angle. The slacker head tube angle (b) moves your front wheel further in front of you. Take it to the trail, and this slacker head tube angle (b) boosts stability and control for confidence when descents get steep and rowdy.


To balance a slacker head tube angle (b), the Marlin features a steeper (more upright) seat tube angle (d). A steeper seat tube (c) lets you get the most out of every pedal stroke, so you don’t waste power on the climb to the top.


The Marlin is equipped with a short stem and wider handlebar for more direct control and responsiveness when you’re manoeuvring through rocks and roots. Meanwhile, a longer reach (e) gives you extra stability so you can ride faster and more confidently.

Secure your ride

A new Thru-Skew axle provides better rear wheel security, holding your wheel in place snugly and ensuring it doesn't slip out of the frame, even when you're rolling through rough-and-tumble terrain.

Fully guarded

Full-length, full-coverage guards on the chainstay protect your frame and keep your ride quiet.

Float on the trail

Big 2.4˝ tyres elevate traction, so you stay planted on dusty switchbacks. But not only do bigger tyres give you more grip — they also soak up bumps for a smoother ride.

Upgrade ready

With a frame this nice, you won’t want to part ways with your Marlin as your skills grow. The Marlin Gen 3 is upgrade-ready, so you can upgrade your bike when you upgrade your skills.

New internal cable routing lets you install a dropper post – and sizes XS and up can be upgraded to a bigger 120 mm fork when you’re ready to take on bigger trails.

A bike for everyone

We believe that every rider deserves a well-fitted bike, that’s why the Marlin is available in every size from XXS to XXL – and even an 'extra-medium' size for riders who fall in between a medium and large. Each size is tuned to its riders, with Smart Wheel Sizing that scales the wheel size with the bike size, so every rider has comfortable standover height. Smaller, XXS and XS frames also feature a curved top tube to boost confidence and make getting on and off a breeze.

Make Marlin yours

Whether you’re regularly ripping up the trail or a rugged city commuter, your Marlin can be fully customised with a treasure-trove of accessories. From kickstands and grips to bottle cages and bags, you can turn your Marlin into the perfect bike for your everyday ride.

Trek warranty and backing

We believe that when you put your heart and soul into something, you should have the stomach to back it up. That’s why we stand behind all Trek bikes with a limited-lifetime warranty.

From your first ride to your 500th, we’ll be here for you in the unlikely event that something goes wrong with your Marlin. All you have to do is pop into your local Trek retailer and you’ll find all the support you need to get back spinning in no time.

The Marlin family

Both generations of Marlins are true mountain bikes aimed at the rider who wants a versatile hardtail capable of off-road singletrack or in-city missions. Both generations have a 100 mm travel suspension fork and 29” wheels on most sizes except for smaller sizes with proportionate suspension travel and wheels, thus making it a great bike for shorter riders as well.
