Rockrider Mountain Bikes are Decathlon's range of off-road bikes which were previously released under the B'Twin brand. In 2018 Decathlon reached the decision to divide up their B'Twin series of bikes into several smaller brands, each dedicated to a different genre of riding.
Rockrider is their new mountain bike range, and comprises of a series of hardtails, full suspension and electric mountain bikes.
Due to their global status, vast purchasing power and combining the role of retailer and manufacturer, Decathlon are able to provide exceptional value for money, with specifications which are often superior to traditional mountain bike brands.
Similar UK shop owned brands include Polygon at Go Outdoors, Pinnacle Bikes at Evans Cycles and Carrera from Halfords.
Other B'Twin ranges include the urban Elops city bikes, speedy Triban Road Bikes, sleek Riverside hybrid bikes and handy Tilt folding commuter bikes.
Rockrider MTBs prices vary from £200 for the Rockrider ST 500 Kids MTB, to £3800 for the Rockrider Race 900 Team Edition XX1 AXS MTB.
