The 2025 Trek Marlin 6 Gen 3 Hardtail Mountain Bike is the perfect ride for progressing your skills on the trails. Its updated slacker frame geometry makes it easier to control on descents while the upgraded suspension fork takes the edge off bumpy trails. Integrated rack and kickstand mounts make it easy to add accessories to this versatile steed.
The Marlin is built around a lightweight aluminium frame with internal routing to protect your cables and add to the bike's sleek look. Big tyre clearance and slack, confidence-boosting geometry keeps you stable from singletrack to city. The frame and wheels vary according to the size of the bike. The XXS and XS bikes have a curved top tube to reduce the standover height. The XXS bikes comes with 26" wheels, the XS and S sizes come with 27.5" wheels and all other sizes come with 29" wheels.
The Marlin 6 comes with a 100 mm RockShox Judy front suspension fork that cushions rocks, roots and bumps in the trail, 10-speed fuss-free Shimano CUES shifting and the serious stopping power of hydraulic disc brakes.
This is an ideal trail bike for riders who want to progress on the dirt, and want a bike that can keep them rolling off of the trail, too.
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.
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.
We understand that price is important, so we regularly price-check our competitors to make sure we have the best offers available. We recognise that we will not always be the cheapest, so if you see the same product cheaper from any of our competitors then please get in touch via the form below and we will do our best to match any reasonable advertised price.
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.
