fourstroke 01
fourstroke 01 Profile More than a race bike The BMC Fourstroke is one of the very few full suspension 29er mountain bikes successfully used on the WorldCup level. This fact alone sets it apart as an outstanding race bike. But then the Fourstroke was always meant to be much more than that. The 29er wheels in conjunction with our BWC geometry, APS suspension and high overall stiffness inspire so much confidence that the BMC fourstroke is also an incredibly fast and capable trail bike. If there is just one category the Fourstroke 01 fully belongs to, this is quite simply mountain biking.

sa drop reach Concept
Frame – APS suspension, 100 mm travel – BWC 29er geometry – Full carbon frame – 12×142 mm rear axle – Frame weight: 2040 g including all hardware Hardware includes: rear shock, chain guide, bolts, seat clamp, and rear wheel axle – Shock dimensions: 200×50 mm
Lightweight Though the Fourstroke 01’s optimized carbon fiber design dances within the 2 kg frame weight barrier, its supremely light weight does not detract from the ride quality. BMC’s Advanced Pivot System (APS), specifically with our big wheel geometry, provides the perfect balance of comfort, control and efficiency.
trail Geometry
Fast Thanks to the Teamelite’s Big Wheel Concept (BWC) geometry, the bike feels stable yet nimble, letting you effortlessly charge a line through steep, technical single tracks. For high speeds, the bike’s low bottom bracket, long top tube, and relaxed head angle work together to keep the bike stable and its rider confident on the roughest trails.
