B'Twin Bikes

B'Twin are a popular choice of bike in the UK, partly due to their widespread distribution by Decathlon, and partly due to the value they offer. Their bikes are divided into several slightly overlapping ranges, with Triban best known for road and gravel bikes, and Rockrider gaining a reputation for high performing MTBs to suit every budget. Elops largely consist of a range of city bikes, whereas Riverside focus on hybrids. All in all, B'Twin bikes are well worth checking out given the size of their ranges; there's a model to suit most budgets.

Rockrider Mountain Bikes

Rockrider are Decathlon's off-road offerings, comprising of a series of kids bikes and adult hardtails, full suspension steeds and even a handful of high end E-MTBs.

This brand was launched in 2018, when Decathlon decided to split their B'Twin bikes into different genres. In terms of prices, there's something for everyone, with adult's MTBs starting at just over £200 and rising up to high end lightweight race bikes at nearly the £4000 mark.

If you want to ride off-road, and would prefer to buy from Decathlon, then the Rockrider mountain bike range is for you.
