The Steppenwolf Tundra 9.0 embodies the new generation of accessible and incredibly high-performance all-carbon enduro electric mountain bikes. With its 29-inch carbon frame, DJI Avinox M2S motor delivering up to 150 Nm of torque in Boost mode, and 800 Wh battery, this model repositions the performance-to-price ratio in the world of high-end electric mountain bikes. Weighing only 21.7 kg, the Tundra 9.0 combines lightness, explosive power, and extended range to tackle technical trails, long climbs, and aggressive descents with total control.

New Avinox M2S motor: power and cutting-edge technology

The beating heart of the Tundra 9.0 is the DJI Avinox M2S motor, DJI's technological flagship in the world of electric mountain biking. With a peak power of 1500 W and a maximum torque of 150 Nm in Boost mode (130 Nm continuous), this motor weighing only 2.59 kg pushes the limits of performance while maintaining a compact format. The flat wire winding technology optimizes the internal space of the motor and increases copper density, reducing electrical losses and maximizing energy efficiency (84.5% efficiency). The Dual Gear Engagement system with helical gears ensures smooth, quiet, and durable power transmission, even under maximum load. Thanks to the integrated temperature sensors and optimized thermal design, the motor maintains its performance even during long sustained climbs. Paired with a 42-point speed sensor on the rear wheel, traction control is surgically precise, ideal for technical sections where every watt counts.

Range and intelligent connectivity

The integrated Avinox 800 Wh battery offers generous range for long rides and significant elevation gains. Certified IP56, it withstands the elements and integrates perfectly into the carbon frame to preserve the bike's sleek aesthetics. The 168 W 4A charger included as standard allows a full recharge in just a few hours. The 2-inch OLED touchscreen displays real-time speed, assistance modes, battery status, and cadence. Via the Avinox Ride app, you can finely customize assistance modes, adjust torque, track your ride data, and even activate automatic heart rate-based assistance control to maintain constant effort in a target zone. Compatibility with the Apple Find My network and integrated security features enhance anti-theft protection.

Carbon chassis and modern all-mountain geometry

The 29-inch carbon full-suspension frame of the Tundra 9.0 combines stiffness, lightness, and precision handling. The progressive geometry adopts a long reach, a slack head angle, and a balanced wheelbase, ensuring stability at high speed and agility in technical sections. The 160 mm travel front and rear provides comfort, traction, and control on all types of terrain, from rocky paths to wet roots. The frame discreetly integrates the battery, improves structural rigidity, and lowers the center of gravity for optimal maneuverability.
