The 2022 Trek Fuel EX 5 Gen 5 Full Suspension Mountain Bike is the gateway to full suspension trail bikes. Fuel EX 5 has the same lightweight aluminium frame technology as the higher-end alloy Fuel EX models with parts chosen to keep the price tag low and performance level high on a mountain bike with exceptional versatility.

You get a high-end ride at an exceptional value with frame features like Boost148 and ABP that give you confident handling and room to upgrade parts as your skills grow. A lightweight aluminium frame with a Straight Shot down tube for extra stiffness in the rough, a Knock Block steerer stop to protect against spinning bars—Trail-taming 140 mm RockShox Recon RL fork and X-Fusion Pro 2 shock 130 mm rear suspension. The RockShox fork's Solo Air spring is easily adjusted for specific rider weight, and it's lighter than a coil spring. A durable 12-speed Shimano Deore drive train. The dropper post lets you lower your saddle on the fly, so it's out of the way on descents and hydraulic disc brakes.

An expanded size range ensures a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5 wheels, S frames get to choose between 27.5 or 29 and sizes M to XL get 29 wheels. The Fuel EX 5 has the capability of far more expensive trail bikes: it shreds singletrack and can even handle the occasional XC or enduro race.

This bike is perfect for

You're ready to go full suspension, and you want a versatile trail bike at a great value. You want a ride that's sure-footed, capable and responsive, so you can stay in control no matter where you're riding.

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.
