Trailfox AMP SX

Keeps you riding…

…over rough, rocky sections, up and down tough Enduro tracks, and sometimes it’ll even make you fly – providing you hook off that drop with style.

The Trailfox AMP SX is for riders that love to shred. Be it your local self-dug trails where you couldn’t convince the city to build a chairlift, or that awesome stage on your local enduro race, this bike has the skills to match yours.

How’s it different to your high-end capable Enduro bike? Its pure power makes going up as much fun as coming down. Win – win? Yes!

With the Trailfox AMP SX we’ve developed a bold Enduro bike that stays in control when things point downwards. Its suspension system, frame design and every detail have been specifically created to maximize your experience. To give it real Enduro pedigree and control in every situation, the bike features an appropriately slack head angle, generous travel, and proper tires.

This bike makes you a better rider; just pull off on the section where you needed to step back in the past. Sleeves up, the Trailfox AMP SX will keep you riding.

 

A tailor-made Enduro weapon

Trailfox AMP SX is the perfect blend of an Enduro and modern e-mtb. A progressive geometry and suspension kinematics developed for the unique demands of aggressive e-mtb riding allow for full speed and a maximum of control. 

Best material choice

The Impec Lab’s new Twin Hollow-core technology results in a world-class, carbon mountain bike frame that integrates the battery and drive unit in one sleek package. 

Go bigger!

The 170mm-travel travel fork, powerful, four-piston brakes, burly downhill-ready tires, and Renthal handlebar and stem combo meet the demands of the gravity-fueled rider.  

More time on the trail

The Shimano E8000 drive unit delivers smooth and powerful pedal assist allowing mountain bikers to cover more terrain than ever before.

Twin Hollow-core Tube Design

For the main frame we opted for a full-carbon chassis. Carbon gives us huge freedom when it comes to shapes and angles. Through the use of carbon, we can also add extra stiffness to specific tube shapes – such as our new Twin Hollow-core tube design; a downtube that takes an integrated battery but is still super stiff.
