BMC TRAILFOX AMP SX ONE

E-MTB Specific Geometry
Our Impec Lab engineered the Trailfox AMP’s new frame from the ground up to keep a long-reach and short-chainstay feel. We designed the frame to take advantage of a lower center of gravity typical of e-MTB’s and the specific way they are ridden. We slightly raised the bottom bracket but held on to the slack head-angle, plush travel and agility of an all-mountain ride. With Shimano’s E-8000 Steps we were able to implement short chain-stays for a snappier ride feel preservation of a standard MTB Q-factor.

APS – Advanced Pivot System
Trailfox AMP’s tailored kinematics, pivot placement, leverage ratios, and shock dimensions bring all-mountain manners to an e-MTB. Delivering a smooth ride so you are prepared for what’s beyond the berm.

The best suspension designs provide control and confidence so you can ride without hesitation. The same unified rear triangle as our other APS designs, with two oversized links, create a strong, durable rear end that delivers rider comfort and excellent control. Its stiff pedaling platform, and active suspension, deliver efficient, smooth operation both up and down – without ever compromising fun-factor.

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 Technology increases overall frame stiffness – critical on a heavier bike with additional components such as a drive unit. Twin Hollow-core tube 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.
