trailfox TF03 29 allmountain

  • Movie

The Swiss army knife with the longer blade

In the trailfox, we've created a frame whose geometry delivers the full wish-list to meet the demands of aggressive all-mountain riding. It is bigger, more aggressive, and more capable than ever before.

Sharing geometry and based on the same design ideas as the trailfox TF01, the TF03 was designed for those looking for a capable, yet economical bike that will let them experience the thrill of enduro riding.

Efficient: The TF03 frame is made of triple-butted and hydroformed aluminum, with a stiffness profile on par with the full carbon TF01 model.

Confidence inspiring: The relaxed angles, low center of gravity, wide bars and short stem of the TF03 give you the control you need on steep, technical sections of trail, or at high speeds. The big wheels increase stability and offer better grip and rollover in technical sections of trail.

Agile: The short chain stays, short stem and low bottom bracket are the keys to the agility you experience on the trailfox. This agile feel, together with the sure-footedness of the big wheels, allows you to own the terrain on a whole new level.

Big Wheel Concept

Our Big Wheel Concept geometries are dedicated to the 29er wheel size.

Simply incorporating bigger wheels does not by itself make a better bike, and we are convinced that the best bikes are made by taking advantage of large wheels and a deliberate geometry. For BMC, performance is not about the size, it’s about the details.

Agility - Short chain stays and stem combined with a low bottom bracket means the bike in not only efficient but also fun and lively.

Stability - Slacker than usual head angle combined with a long top and wide handlebars help you stay in control through the worst lines.


advanced pivot system

Unsurpassed power transmission, traction control, and comfort.

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.
