The Bosch "Gen 5" Performance CX motor launched as a 85Nm motor. Bosch periodically release updates for their drive systems, normally for reliability and performance. Recently, Bosch announced the option for an extra 35Nm of torque.
This bike will come with the latest update of 120Nm torque output already installed. This update unlocks up to 600% maximum assistance in Turbo mode. You can adjust the power back down if required by using the Bosch eBike Flow App.
The new eMTB+ riding mode delivers dynamic support at the highest level, blending the smooth control of eMTB mode with the full power of Race mode - offering up to 600% maximum support. It's available as part of this new firmware update.
Extended boost remains easy to modulate like in eMTB mode, while unleashing the full force of Race mode when needed. Up to 750 watts of power is delivered naturally and responsively, based on your pedal input. eMTB+ gives you the best of both worlds - combining agility, performance, and control for a truly natural riding experience. It is also possible to maintain peak power for longer, depending on riding conditions.
Features
The 2026 Haibike AllMtn 4 redefines the "price-to-performance" ratio for serious e-MTB riders. By pairing the cutting-edge Bosch Performance CX Gen 5 motor (120Nm) with a massive 800Wh battery, it offers high-end range and torque typically reserved for much pricier models.
Its robust aluminum frame utilises a mullet wheel setup for agile handling, while the RockShox Psylo Gold RC fork and SRAM NX Eagle drivetrain provide race-ready reliability without the carbon-fiber markup. It is professional-grade power made accessible.
The 2026 Haibike AllMtn 4 features an upgraded suspension system led by the RockShox Psylo Gold RC front fork and a Deluxe Select R rear shock. The Psylo fork delivers 160mm of travel using an ultra-stiff 35mm chassis and the new Isolator RC damper, which provides superior stability under high-torque loads.
Paired with 150mm of rear travel and adjustable rebound damping, this setup ensures a balanced, plush ride that maintains traction and control on even the most technical descents.
Brakes & Gears
Gemini said The 2026 Haibike AllMtn 4 upgrades to the SRAM DB8 Stealth 4-piston hydraulic brakes, offering a "set-and-forget" alternative to high-maintenance systems. Utilising a robust mineral oil platform, these brakes provide consistent, "Code-like" heavy-duty stopping power with significantly longer service intervals.
The new Stealth lever design keeps hoses tucked close to the bars for a cleaner cockpit, while large 200mm rotors ensure reliable heat management and precise modulation on the steepest, most demanding technical descents
The 2026 Haibike AllMtn 4 features the revolutionary SRAM Eagle T-Type drivetrain, a wireless system built specifically to handle the Bosch motor's 120Nm of torque. Unlike traditional gears, it utilizes a hangerless interface that mounts directly to the frameâs rear axle for unprecedented strength.
This "Transmission" design allows for flawless, quiet shifting even under full motor assistance. With its robust 10-52T cassette and ultra-durable flattop chain, it provides a massive gear range for conquering the steepest technical climbs.
The 2026 Haibike AllMtn 4 features SRAM DB8 Stealth brakes, providing low-maintenance mineral oil technology with "Code-like" four-piston power. Their streamlined lever design ensures consistent, reliable stopping for aggressive e-MTB riding.
The 2026 Haibike AllMtn 4 features the SRAM Eagle 70 T-Type drivetrain. This cable-actuated Transmission offers a hangerless interface and 10-52T range, providing robust, precise shifting under heavy e-MTB loads
The SRAM T-Type mechanical shifter offers a light, crisp action specifically tuned for e-MTB loads. Its ergonomic design ensures precise gear changes across the 10-52T cassette with minimal effort.
Wheels & Tyres
The 2026 Haibike AllMtn 4 uses a XLC WR-M39 (29") front and WR-M37 (27.5") rear "mullet" configuration. This setup combines the superior rollover of a large front wheel with the nimble, high-traction characteristics of a smaller rear.
Built with 30mm internal width double-walled aluminum rims and 32 reinforced spokes, these wheels are specifically engineered to withstand the massive 120Nm torque of the Bosch Gen 5 motor.
The 2026 Haibike AllMtn 4 is equipped with Continental Kryptotal tyres, specifically the Kryptotal-Fr (Front) and Kryptotal-Re (Rear). This setup uses the Trail Endurance casing, balancing lightweight agility with the puncture protection needed for aggressive e-MTB riding.
The front tyreâs open tread pattern is optimized for steering precision and braking stability, while the rear features ramped lugs to reduce rolling resistance and maximise traction under the Bosch motorâs 120Nm of torque. Itâs a versatile, high-grip combination for mixed terrain.
The bottom line..
In 2010, Haibike fundamentally changed cycling by launching the eQ XDURO, the worldâs first truly performance-oriented electric mountain bike. While other brands dismissed e-bikes as "commuter toys," Haibike innovatively inverted the Bosch motor to create the high ground clearance necessary for off-road trails.
This "gravity casting" technology became the blueprint for the modern e-MTB industry. By the time major competitors entered the market years later, Haibike had already defined the category, proving that electrification belonged on the mountain.
The 2026 Haibike AllMtn 4 is defined by its "German-engineered" reliability, featuring a newly developed 6061 aluminum frame designed to withstand a massive 135kg system weight. Utilising Haibike's signature Gravity Casting technology, the motor is cradled in a high-stress-tolerant housing that doubles as a heat sink.
This robust construction, paired with a five-year frame warranty and IPX-rated Bosch component integration, ensures the bike remains rattle-free and resilient through years of aggressive, high-torque trail use.
Power
The 2026 Haibike AllMtn 4 is powered by the Bosch Performance CX Gen 5 motor, delivering a massive 120Nm of torque and 750W peak power.
This unit is paired with the PowerTube 800, Boschâs highest-capacity internal battery, offering incredible energy density for epic all-day rides.
Control is centralised through the Purion 200 displayâa compact, high-resolution color screen mounted ergonomically at your thumb. It displays vital ride data while doubling as a control hub for the Bosch eBike Flow app.
Through the app, you can customize motor dynamics, receive over-the-air updates, and use the eBike Lock digital anti-theft feature.
Together, these components create a smart, high-performance ecosystem that ensures you have the power to climb anything and the intelligence to track every stat.
The Purion 200 display offers a clear, full-color interface for intuitive access to ride data and motor settings. Its user-friendly design enhances control and visibility, optimizing your riding experience.
The Bosch Gen 5 Performance CX motor delivers an impressive 120Nm of torque, ensuring powerful acceleration and climbing ability. Its lightweight design enhances overall bike performance, offering a natural and responsive ride.
The new Bosch 800Wh PowerTube battery offers unprecedented range and power, enhancing eBike performance. Its compact design integrates seamlessly into the frame, providing riders with longer adventures and reduced charging frequency.
