Trek Fuel EXe electric mountain bike uses the TQ Harmonic pin ring motor

TQ Harmonic Pin Ring motor

The TQ harmonic pin ring transmission is what makes the Fuel EXe stand out— the unique design is smaller, lighter, quieter, less noticeable, and more fun to ride than traditional eMTB motors. 

The basic idea is that it gives you a more natural ride quality that feels more like a mountain bike than an heavy, overpowered motorbike. That being said, it still pushes out an impressive 50 Nm of torque and assists up to 20 mph. 

The integrated display sits flush with the top tube so it’s there when you need it and out of sight while you’re busy shredding. The smaller package means no bulky downtubes or bottom brackets; you can barely tell it's an ebike just by looking at it!

Hidden battery

The 360 Wh battery sits discreetly inside the low-profile downtube that’s 39% smaller than ones found on traditional eMTBs. 

The battery can provide between 2 to 5 hours of pedal assist and can reach up to 7.5 hours with the optional Range Extender that neatly fits inside the water bottle cage. The battery can be easily removed with a hex wrench.

Featherweight eMTB

The Fuel EXe pioneers a new class of lightweight eMTBs. The TQ motor is smaller than your chainring and weighs just 1.85kg while the entire drive unit with battery measures 3.9 kg. 

Trek’s OCLV Mountain Carbon frame sheds additional grams for a lively and playful ride out on the trails.

Trail-ready package

A trail bike at heart, the Fuel EXe rocks the right geometry to perform well no matter which way it’s pointing. 

The slack, stable front end hooks up with a steep seat tube angle for efficient pedaling uphill. The plush suspension setup features 150mm of travel up front and 140mm at the rear while 29er wheels allow for up to 2.6” of tire clearance.
