No compromises - APS suspension technology allows you to pedal hard, brake fast, and soak up bumps without compromise.
The Speedfox AMP boasts what BMC calls “Twin Hollow-core Technology.” Developed at the BMC Impec Lab, this new carbon technology is BMC’s solution to the challenge of creating tube shapes big enough to accommodate a battery, yet stiff enough to qualify as the front triangle of a trail e-mtb. The Twin Hollow-core front triangle is complemented by a Premium Carbon rear triangle to optimize torsional stiffness and weight while delivering a clean, seamless look. Additional loads generated by the Speedfox AMP being an e-MTB, have been addressed with upsized bearings and links. A one-piece rear triangle ensures torsional stiffness targets are also met.
BWC - Big Wheel Concept
The Big Wheel Concept is aimed at optimizing geometry and cockpit fit to improve the natural qualities of 29” wheels: The Speedfox AMP features a slack head angle and a generous reach to improve stability, while short chainstays deliver a lively riding feel. We also maximized bottom bracket drop for a low and centered riding position, increasing riding confidence and control as a result.
Twin Hollow-core Technology
How do you create a stiff frame that holds a battery and drive unit, yet still performs like a world-class mountain bike? The Trailfox AMP’s innovative new Twin Hollow Tube Technologyincreases overall frame stiffness – critical on a heavier bike with additional components such as a drive unit. Twin Hollow-coretube shapes also allow us to integrate components, protecting them from wear and tear. And last but definitely not least – they let us adhere to the design principles we are famous for. The Trailfox AMP doesn’t compete for attention – it commands it.
APS Suspension
BMC engineers have tailored the Advanced Pivot System (APS) suspension and applied it to the Speedfox AMP. The re-calculation of APS’ kinematics, pivot placement, and leverage ratios, combine with an e-specific shock tune to give the Speedfox AMP a true trail bike attitude.
