On-One S36 Downhill Bike

On-One S36 Downhill Mountain Bike

The S36 is for every rider who ever wanted a bike that they could ride downhill lap after lap, day after day and keep them smiling as they make their way back to the top.

Sheffield born and bred, the S36 name represents the postcode of our favourite 'Wharncouver' trails. We've tested it at trail centres, uplifts and downhill days all over the UK and now it's ready for your favourite trails.

Designed to be ridden downhill, fast, the S36 packs in 8" of progressively tuned suspension travel. With stable and slack geometry it tracks technical trails with ease and confidence, helping you to ride more laps and progress your riding.

Built to last with massive bearings, oversized bushings and huge frame gussets you can rely on the S36 to deliver the goods.
