Natural look. Natural ride. Surprisingly electric.
Hiding in plain sight
Sometimes the beauty isn’t in what we see, but what we don’t. Nestled neatly behind the front chainring, the naturally advanced harmonic pin ring transmission blends in effortlessly. Its petite package allows for a 39% smaller down-tube than a traditional e-MTB, resulting in a ride that fits right in with traditional mountain bikes on the trail.
Tiny but mighty
Desipite being smaller than your chainring, the drive unit hits with 50Nm of toque.
Good sounds. Bad sounds.
Less is more
When we’re on the trail and connecting with nature, we don’t want to hear more than the sound of our tires on the dirt, the wind through the trees, and the hoots and hollers of our riding crew. Up until now, e-bikes have pulled us away from that experience with high-pitched motors that take us out of the element. Fuel EXe is different. It’s not only quieter—it’s less annoying.
Data recorded in an anechoic chamber using a calibrated B&K 4966-h-041 microphone and Siemens SCADAS data acquisition unit with an acoustically-isolated Wahoo Kickr trainer set to 300W total resistance and bikes in maximum assist mode. Microphone was located 1 m laterally from the bottom bracket and 1.7 m off the floor (head height) and sampled at 51,200 Hz. Tonality calculated in Siemens Testlab Neo according to the ECMA-74:2019 standard.
While some e-bikes feel cumbersome and bulky, Fuel EXe is light, nimble, and playful, just as a trail bike should be. Its capable geometry is finetuned for barreling into berms and making light work of tech trails, lacing turns through tight aspens, and gnawing through rowdy rock gardens. Instead of being flung uphill like a rocket launcher, Fuel EXe’s assist feels natural, barely there — like an extension of your own power, so you can ride just like you would on a traditional mountain bike.

Dialed for how you ride
Mino Link lets you quickly and easily tweak your geometry, so your bike is always tuned perfectly for the terrain and your riding style. .
With 50Nm of torque, Fuel EXe has just the right amount of force for cranking up steep climbs without launching you forward with jerky propulsion. It finds the sweet spot between too much and too little for a ride that’s natural and smooth, but not overwhelmed.
There s nothing like it
The harmonic pin ring transmission
Most e-bike motors use gears and belts to move you forward— but belts and gears lash, slip, rattle, and wear out over time. That disconnects you from the ride. Fuel EXe uses a motor unlike anything else out there—the TQ harmonic pin ring transmission. The harmonic pin ring transmission is not only smaller and lighter than traditional e-bike motors, but because it has fewer moving parts it’s also smoother, quieter, and more durable. It delivers more of the ride experience without any downside.
