E-Specific Frame Technology:

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

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.

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.
