The 2023 Trek Marlin 6 Gen 2 Hardtail Mountain Bike is a cross-country mountain bike built to give you an efficient off-road ride with a suspension fork that locks out, and a simple 1x drivetrain. It's made for mountain biking, but it's also equipped with features like rack and kickstand mounts that make it a great choice for adventurous daily commutes.
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 6 comes with tried and tested Shimano Deore 1x10 gearing. The wide-range cassette still gives you all the gears you need for big climbs. Tektro hydraulic disc brakes give great stopping power. Plus the Marlin 6 comes with a suspension fork that lets you easily lock the suspension so you don't waste energy on smooth terrain.
This bike is perfect for
Riders who are testing the waters of off-road riding, and want a real mountain bike at a great value, with a wide range of gears to cover more ground on the road and trail.
Key Features
- The 1x drivetrain gives you all the gears you need, and none you don’t
- 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.

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:
Build only products we love. Provide incredible hospitality to our customers, and change the world by getting more people on bikes.
