The 2023 Trek Marlin 5 Hardtail Mountain Bike 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.

The Trek Marlin is built around a lightweight aluminium frame with internal routing to protect your cables and add to the bike's sleek look. The bike comes in lots of sizes and Marlin models in XSmall and Small frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount. The smaller bikes also have smaller wheels with XXSmall bikes running 26” wheels, XSmall and Small bikes running 27.5” wheels and bikes from medium up running 29” wheels.

The Marlin 5 comes with 16 speed gears, 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.

This bike is perfect for

New riders who want a real mountain bike that can handle the trails but can also double up as a commuter. With hydraulic brakes, better quality gears and a lockout fork this is a significant upgrade from the Marlin 4.

Key Features

  • 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
  • Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • Smaller frame sizes (XXS 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 and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
  • Like every Trek, it's backed by a lifetime warranty

Mountain Bike Buying Guide

Mountain biking is an incredibly diverse sport. Mountain bikes now come in three main flavours. They are XC, Trail and Enduro.

XC – short for cross country, are quick race bikes. They will normally have 29” wheels and come with 100mm of suspension. If you are mainly going to be riding bridleways and natural trails in the South East of England, where our shops are, an XC bike will be the quickest and most efficient option.

Trail – these bikes are designed to be pedalled up and down hill and for use on bridleways and natural trails, but also at dedicated trail centres. They normally come with 130mm or 140mm of suspension travel and can have either 27.5” or 29” wheels, but 29” is quickly becoming the norm. Trail bikes are good all-rounders. They won’t be as fast as an XC bike on the flat but they can handle a lot more challenging terrain, and a few jumps. If you plan on taking your bike to trail centres in Wales, or to the Alps, then a trail bike may be your best option.

Enduro – enduro racing is a thing in and of itself but many people buy enduro bikes for ‘aggressive’ trail riding and uplift days at places like Bike Park Wales. This generally means challenging downhill trails with some big jumps. With around 160mm of suspension travel enduro bikes can take some big hits. They are designed to be efficient enough to pedal up hills but really come into their own when pointed downhill. You get enduro bikes in either 27.5” or 29” wheel sizes as well as mullet setups of 29 at the front and 27.5 at the back.


Men’s and women’s mountain bikes

Nearly all the mountain bikes we sell are now unisex. All of the big brands have gradually stopped doing dedicated men’s and women’s bikes over the last few years. Instead they are focussed on producing bikes in a bigger range of sizes. So, for instance, the Trek Marlin 5 is a unisex bike that now comes in sizes from XXS to XXL large. This means it will fit riders from 4’ 5” to 6’ 5” and everything in between.
