3T e-Extrema Electric Gravel Bike – Power to Conquer Every Surface

The 3T e-Extrema electric gravel bike is built for riders who want to go further across road, gravel and technical terrain. It combines a lightweight Made in Italy carbon frame, aerodynamic performance and the natural assistance of the Mahle X20 rear hub motor.

POWER TO CONQUER EVERY SURFACE

We started with the exact same Made in Italy carbon frame as the non-electric Extrema, engineered with 3T’s proprietary Filament Winding + RTM technology.

Its aerodynamic design keeps speeds high on both road and off-road. With a slightly more upright geometry than the e-Racemax and the Mahle X20 rear hub motor, the e-Extrema excels when the terrain gets rough and technical.

Running WAM 29"/700c tires (47–57mm) gives you maximum traction, control and puncture resistance, perfect for handling the extra power of the motor.

Integrated cables via the MORE system, wireless dropper compatibility and fork mounts make this electric gravel bike ready for extreme adventures and bikepacking.

THE HIDDEN BOOST

Built to perform on the steepest gradients and the most challenging surfaces, the e-Extrema is the most versatile e-bike in the 3T lineup.

Lightweight, agile and ready for adventure, with the added boost of electric power.

All electronics, cables and batteries are housed inside the downtube, with no bulky profiles or unsightly external modifications. The Mahle X20 rear hub motor preserves the original geometry and delivers an unmatched natural ride feel.

POWER, EFFICIENCY & LIGHTNESS

The e-Extrema features a hand-built carbon frame made in Italy with 3T’s proprietary technologies and an impressively low weight.

Equipped with the Mahle X20 motor customized for 3T, delivering 65Nm torque, paired with a 350Wh battery for smooth, progressive power.

The Mahle system offers Bluetooth & ANT+ connectivity, Garmin compatibility, three preset power modes, and a fully customizable fourth mode via the MySmartBike app.

With smart power management, you can easily achieve 150+ km range and 2000 m elevation gain*.

Need more autonomy? Add the optional 173Wh range extender (1.1 kg) mounted in the bottle cage for +50% extra range.

*Average for a rider under 75 kg on mixed gravel/asphalt routes, EU speed limit of 25 km/h.

REALFAST AERODYNAMICS

Starting from our favorite tires and allowing space for knobs and mud, we designed the rear wheel cutout as close as possible to the seat tube and a large downtube to guide airflow from the front wheel.

We engineered a head tube that accommodates a robust fork steerer, aero-optimized seat stays and bottle placement sheltered from the wind.

Most importantly, we designed everything for real-world speed, considering crosswinds, tire width, bottles, accessories and even mud.

The 3T e-Extrema is fast and efficient where it matters: on the trail, not just in a wind tunnel.
