Mountain Bikes
Mountain bikes are perfect for exploring trails, bridleways and byways that seem out of reach by foot. Looking to take your performance to the next level? A cross country mountain bike is a fantastic choice. Should you wish to tackle big drops and extreme trails, an enduro mountain bike takes whatever you throw at it in its stride. For those searching for a truly versatile option, trail mountain bikes are the go to for those wanting the speed of an XC Mountain Bike with the singletrack crushing ability of an enduro mountain bike. If you’re worried about gradients, fear not, electric mountain bikes hold the key to unlocking stunning views from far-off hills. Explore more on our Mountain Bike Hub.

Choosing your mountain bike
When it comes to choosing your mountain bike, it's a good idea to choose a model that suits your niche. A trail mountain bike makes a great choice for most first-time MTB buyers, offering a fantastic blend of speed, agility and all the singletrack ability of an enduro mountain bike. It's arguably the most versatile type of MTB out there.
With such a rich variety of models on the market, it's important to get to know a few. We've listed a few of our top picks below.
Cross country MTBs
Also known as an XC, cross country mountain bikes deliver the most exhilarating ride. Lightweight frames and top-spec components let you breeze through the most brutal uphill efforts and flow through technical descents. If you're thinking of competing, you can find flat-out acceleration with an XC mountain bike.
Enduro mountain bikes
Enduro mountain bikes strike a balance between versatile trail and downhill mountain bikes, built for all-out descents and featherweight climbing. Choose from aluminium or carbon fibre frames and enduro hardtail or full suspension mountain bike options to find an enduro bike that suits you, even on the trickiest ground.
Electric mountain bikes
When the going gets tough, you can push back harder. With an electric mountain bike, you'll get an extra boost from a powerful motor tucked away within the frame. These mountain bikes make it possible to explore the steepest trails and the most rugged bridleways with ease. At the push of a button, you can breeze through every new route.
