Decathlon has a wide range of men’s mountain bikes to choose from including front and full suspension options to suit different terrains and levels of cyclists. With Decathlon, every bike will prepare you for adventure.

Features to look out for include suspension, adjustable stems, hydraulic brakes, lighter frames and wheels and different styles of saddle. We have both front and full suspension options.

Front suspension provides shock absorption where you need it most and is perfect for occasional to semi-frequent riders. For the more extreme terrains and for professional and very regular bikers, full suspension mountain bikes provide front and rear shock absorbers. This ensures you’re protected from impact and gives you maximum control.

Not sure what size mountain bike you need? Pop into a Decathlon store and one of our experts will help you find the right one. Why not also read our handy guide on how to choose the right mountain bike for you?

As well as men’s bikes, we also have a range of womens MTBs available online or in store.
