Orbea MX 20 Mountain Bike 2021

Getting into a new sport like mountain biking can be daunting, but the simplicity and effectiveness of the Orbea MX 20 Mountain Bike makes for an easy choice. A sturdy but lightweight alloy frame, size-specific wheels and a fork with 100mm of travel amount to a bike with all the features you need and none of the ones you don't. As a hardtail MTB, the MX 20 is best suited to rolling trails, or cross-country riding - with no rear suspension to impede power transfer, it allows you to ride uphill more efficiently.

The Shimano Deore 11-speed gearset is perfect for any terrain, thanks to the wide-ranging cassette. Flick through the gears with ease while the single front chainring makes the system very easy to operate with less chance of dropping your chain. The Shimano hydraulic disc brakes are perfect for off-road riding, with the ability to stop quickly and safely. 2.35" wide Kenda tyres have loads of grip, and with size-specific wheels - 27.5" on the Small and Medium options and 29" on the rest of the range - you get an agile and pacy ride no matter what size you ride.


  • Hard Tail MTB with a great specification for the price
  • Size-specific wheels ensure a great all-round ride
  • SR Suntour XCR32 suspension fork with 100mm of travel
  • Shimano hydraulic disc brakes
  • Shimano Deore M5100 11-speed shifters and derailleur
  • 1x chainset is reliable with less maintenance
  • Kenda K1153 2.35" tyres provide plenty of traction
