The 2023 Trek Marlin 6 Gen 3 Hardtail Mountain Bike is perfect for progressing your skills on the trails. It comes with updated slacker frame geometry which makes it easier to control on descents, while the suspension fork takes the edge off bumpy trails.

The Marlin 6 is built around a lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and keeps the bike looking sleek. Although the geometry is setup for off-road riding it is versatile enough for use on the road and on light trails. The smaller sizes come with 27.5” wheels while larger sizes come with 29” wheels. The XXS and XS sizes also have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount

The Marlin 6 comes with an SR Suntour XCT 30 100mm travel front suspension fork that cushions rocks, roots and bumps in the trail. 1x10-speed Shimano Deore shifting is easy to use and low maintenance while the Tektro hydraulic brakes give serious stopping power.

This bike is perfect for

Mountain bikers who want a bike with modern trail geometry and the latest 1x drivetrain which will also double up for commuting, family rides and general use.

Key Features

  • You get real-deal modern mountain bike geometry that keeps handling confident when you're on singletrack, but is versatile enough for use on roads and bike trails too
  • Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • The new Thru-Skew system is safer, simpler and stronger, plus it makes removing the rear wheel for flat fixes a piece of cake.
  • Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending

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.

Trek made their first bikes in 1976 in a barn in Wisconsin. Now they’re one of the biggest bike brands in the world. Trek bikes cover everything from professional-level road and mountain bike race bikes to commuters, hybrids and kids bikes. There is a strong heritage of racing at Trek and many Trek bikes have a strong race influence. They take a very scientific approach to researching bike and human performance and then make the fastest and most efficient bikes they can.

It doesn’t stop their attention and passion for cycling flows through everything they do. Since the 1990s, Trek has supported Places for Bikes. Places for Bikes is an advocacy organisation in the USA that gets more people on bikes more often! Places for Bikes ethos falls in line with the companies mission statement to:
