B'Twin are Decathlon's own brand of bikes, which are manufactured in factories in Asia and Europe. Originally all Decathlon bikes displayed the B'Twin name, but since 2018 this has been phased out with several distinct ranges being launched instead.
Rockrider covers their off-road series, with both mountain bikes and E-MTBs included.
Their hybrid series are badged as Riverside, and their traditional city bikes and equivalent electric models are labelled with the new Elops branding.
Gravel bikes and road bikes have both been rebadged under the Triban name, from the cheaper entry level bikes all the way up to their UCI approved models.
Finally, their series of convenient folding bikes were relabelled under the Tilt banner, including a few posh electric motor powered folding bikes.
Obviously innovations and technology are constantly progressing, but all of these bikes are essentially B'Twin bikes, just under different branding in a bid to appear more specialised and defined.
If you can't find a suitable B'Twin bike here, it's worth checking out my Carrera, Polygon & Pinnacle pages for other similar retailer owned brand bikes.
