3T eRacemax Italia Red Xplr Axs Discus 45|40

Designed for the toughest terrains and most demanding conditions, the e-Extrema blends aerodynamic efficiency with full compatibility for a wireless dropper seatpost and clearance for tires up to 700×57c. If you’re seeking an e‑bike that goes anywhere — up steep climbs, across rugged trails, and beyond — the e-Extrema is your ultimate choice.

Built around the same Made‑in‑Italy carbon frame as the non‑electric Extrema, engineered with 3T’s proprietary Filament Winding + RTM technology. Its aerodynamic design maintains high speeds both on and off road. With geometry slightly more upright than the e‑Racemax and powered by the Mahle X20 rear‑hub motor, the e‑Extrema excels where terrain grows rough and technical. Fitted with WAM 29"/700c tires (47–57 mm) delivers maximum traction, control, and puncture resistance — perfectly matched to handle the motor’s extra power. Internal cable routing via the MORE system, wireless dropper compatibility, and integrated fork mounts make this bike unstoppable on extreme adventures and bikepacking trips.

Built to perform on the steepest gradients and most challenging terrain, the e-Extrema stands as the most versatile e‑bike in the 3T lineup. Lightweight, agile, and adventure‑ready — with the seamless boost of electric power. All electronics, cables, and battery live fully concealed inside the down tube — no bulky profiles, no unsightly external modifications. The Mahle X20 rear‑hub motor preserves the frame’s original geometry and delivers an exceptionally natural ride feel.

The e-Extrema features a hand‑built Italian carbon frame using 3T’s proprietary manufacturing methods, resulting in an impressively light overall weight. Equipped with the 3T‑tuned Mahle X20 motor producing 65 Nm of torque, paired with a 350 Wh battery for smooth, progressive assistance. The Mahle system offers Bluetooth® & ANT+™ connectivity, Garmin compatibility, three preset assist modes, plus a fully customizable fourth mode via the MySmartBike app. Intelligent power management delivers an estimated 150+ km range and 2,000 m of elevation gain*. Need to go farther? Add the optional 173 Wh range extender (1.1 kg), mounted in a bottle cage, for ~+50% extra range.

We designed the rear wheel cutout to sit as close as possible to the seat tube — making room for wide, knobby tires and mud — while sculpting a large down tube that guides airflow past the front wheel. Up front, a robust head tube accommodates a sturdy fork steerer; aero‑optimized seat stays and sheltered bottle mounting further reduce drag. Most importantly, every shape is tuned for real‑world speed — accounting for crosswinds, tire width, on‑bike accessories, and even mud. The e-Extrema is fast and efficient where it matters most: out on the trail, not just in a wind tunnel.
