Trek has announced an alloy-framed version of its Fuel EXe, bringing the electric mountain bike down to more affordable price points.

The Fuel EXe was initially launched in carbon frame models only. Technical editor-in-chief Robin Weaver found the Trek Fuel EXe 9.9 XX1 AXS to balance its natural motor feel with impressive handling and surefooted geometry.

The new electric mountain bike shares its geometry and 150/140mm travel suspension layout with the carbon models. Trek says you can fit a 160mm fork if you wish, and it’s also coil shock compatible.

There are three models in the alloy Fuel EXe range. They use the same frame which is constructed using Trek’s Alpha Platinum Aluminium tubing and run on TQ’s HPR50 electric bike motor system.

TQ HPR50 motor

Trek was the first brand to spec TQ’s HPR50 system.

The mid-level-assist system packs 50Nm of torque, with the battery storing 360Wh of juice and the display is integrated into the top tube. TQ claims the battery offers around five hours of ride time in eco mode, or two hours in the highest power setting.

Adjustable geometry and a mullet setup

The alloy Fuel EXe promises comparable riding characteristics as its carbon sibling.

Unlike the carbon version of the bike, the alloy Fuel EXe is compatible with angled headset cups.

This enables you to slacken or steepen the head angle by up to one degree.

The alloy Fuel EXe runs on 29in wheels and like its carbon sibling, is compatible with a mullet wheel set-up, provided you set the Mino Link flip chip to the high position.

The Mino Link adjusts the head tube angle by half a degree and the bottom bracket height by 10mm.
