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.

Triban Bikes

The Triban series of Bikes were created in 2018, when Decathlon's B'Twin bikes were divided into different genres. At this point, road & gravel bikes were assigned the Triban moniker, offering both value for money and performance.

Prices for the Triban range start at £300, and increase up to the £1000 mark, resulting in this brand being suitable for beginners and keen road cyclists alike.

If you would like to start road cycling, or dabble in some light off-road riding with a gravel bike, then you won't go far wrong with a Triban bike.
