Race ready, trail proven, all-mountain capable
The BMC fourstroke FS01 is our most capable and diverse mountain bike. It's so versatile, it's hard to pin down its true nature. As one of the lightest all-carbon, full-suspension frames available it's primed to line up at the start of any cross-country race. Yet, with its short chain stays and slack head tube angle, it's equally adept at making
the most rugged trail feel like a Swiss autobahn. BMC's legendary APS suspension and Big Wheel Concept geometry mean complete control, giving the rider absolute confidence at high speed, or in tricky technical situations. If you're looking for one mountain bike that can do it all, look no further than the BMC fourstroke FS01.

APS
advanced pivot system
-

The ideal suspension system converts all of a rider's energy into forward propulsion, while at the same time absorbing impacts. Mechanically, these two goals are at odds with one another. But BMC's APS rear suspension satisfies these two goals by carefully calculating the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock.
How is this accomplished? With APS the virtual pivot point is positioned so that constant chain tension is maintained for forward acceleration. As such, pedaling forces are used for forward propulsion with no loss of energy transfer in the suspension system. At the same time, the shock system ensures optimum rear wheel traction, guaranteeing that those pedaling forces are not only getting to the rear wheel, but to the ground, as well. The end result is a suspension system that provides extreme power transfer efficiency, uncanny traction, and excellent comfort.

Direct assembly of the brake caliper to the frame with no need for an adapter means improved braking power transfer, especially under demanding conditions.

Just set the sag adjustment according to the indicator, and go. Trailside adjustments have never been simpler.
