This is the bike that redefines what’s possible. Powered by Bosch’s fourth-generation drive system and a high-capacity 625Wh battery, the Stereo Hybrid 160 HPC SL’s unique combination of gravity prowess and all-round trail ability sets it apart.
The new RockShox Zeb fork with 38mm stanchions and 170mm travel, Deluxe Select shock and carefully tuned kinematics serve up lots of trail-taming travel. Sram’s Eagle transmission gives you the range you need to take on any climb. And powerful Magura MT Thirty four-piston hydraulic disc brakes – with a remote dropper post – put you in full control. Get your enduro on.
Packing enduro-worthy levels of travel and Bosch e-bike capability into a single frame isn’t easy. But we did it, with style to spare. The carbon main frame houses our Modular Battery System and Bosch power unit entirely within the down tube. Hidden by a double-layer cover with shock protection, push-button access and a hidden lock, the battery is both secure and easy to get to. We even found room for a bottle cage mount. There’s a trunnion shock mount, big bearings, Boost 148 rear end and 1.5in head tube for accurate tracking. And aggressive geometry gives you the advantage you need to show the trails exactly who’s boss.

Bosch eMTB Technology
Bosch Performance Line CX 2021
The Bosch Performance Line CX offers a unique eMTB experience: Compact, lightweight and with more power, it combines high-quality materials, an extremely powerful drive and high-end sensors. This brings eMountain biking on the trail to a whole new level. From model year 2021 with a torque of up to 85 Nm, new features in the motor control and a further development of eMTB mode – all as a software update. For a thrilling riding experience: more natural, intuitive and powerful and an absolute benchmark in its class.
What is new with the Bosch Performance Line CX engine in model year 2021?
Performance upgrade and new features A riding experience that sets the benchmark: From model year 2021, the Performance Line CX ensures even more riding enjoyment on the trail – with further developed software and a maximum torque of 85 Nm. The increased torque ensures greater performance, supporting you with even more power, especially in low cadences. In eMTB and Turbo mode, this leads to significantly faster acceleration and makes hill starts much easier. Thanks to a broader cadence range, unpredictable riding situations can be mastered even more effectively – for example in the case of late gear shifting or accelerating out of tight corners. Riding remains smooth and free from jolts, even when out of the saddle or in Turbo mode.
Next-level eMTB mode The progressive riding mode for every occasion: Advanced eMTB mode ensures eMountain bikers are well-prepared for whatever riding situation the trail may have in store. New sensor and motor control functions give eMountain bikers a much wider range of dynamic and natural support. Riders continue to benefit from the proven technology of eMTB mode: Depending on pedal pressure, progressive motor support adapts perfectly to the riding situation. The improved adjustment of eMTB mode ensures optimum traction control in all gears and enables organic handling (AKA ‘power on demand’). Start-up behaviour is much finer and more sensitive – especially in low gears. Due to the increased torque, the drive unit supports an even wider cadence range.
Extended Boost Extended Boost is the unrivalled function for negotiating exposed roots, steps and stones on the trail with ease, even uphill. The eMTB can be maneuvered with much greater agility and ease on technical sections. The unique dynamism means that obstacles can be overcome with ease by applying the right amount of pressure to the pedal. The pedals rarely, if ever, jam. The new, innovative function in eMTB mode can be controlled to optimum effect in all riding situations. If the front wheel is already on the step, a slight pedal pressure is all it takes to give the decisive “kick”. This takes pedal management to a whole new level.

The new Bosch eMTB mode from 2021 – especially for eMountainbikers
For the ultimate Uphill Flow For powerful eBiking in the mountains and on rough terrain: The eMTB mode of the Performance Line CX and Performance Line switches between the Tour and Turbo modes. To control the bike even on difficult sections, the further optimised eMTB Mode supports eMountain bikers with maximum sensitivity, allied with progressive power delivery: with a maximum torque of up to 75 Nm on the Performance Line and 85 Nm on the Performance Line CX and motor support between 140% and 340%. Depending on the pedal pressure applied, the motor dynamically boosts the rider’s own performance. The eBiker does not have to change the riding modes manually. Starting on steep slopes is no problem, while riding on mountain trails is noticeably easier and the eMountain biker benefits from significantly better traction. This provides a natural riding sensation and optimum performance on the trail.
Improved coordination and extended boost New sensor and motor control functions in the Performance Line CX give you a much wider range of support, even more dynamically and naturally. The improved adjustment of eMTB mode ensures optimum traction control in all gears and enables organic handling (“power on demand”). Start-up behaviour is much finer and more sensitive, especially in low gears. Due to the increased torque, the Drive Unit supports an even wider cadence range. Extended Boost is the unrivalled function for negotiating exposed roots, steps and stones on the trail with ease, even uphill. The eMTB can be manoeuvred with much greater agility and ease on technical sections. The unique dynamism means that obstacles can be overcome with ease by applying the right amount of pressure to the pedal.
Bosch batteries are an efficient, long-life energy source. Thanks to their enormous mileage, long service life and intelligent battery management system, Bosch lithium-ion batteries are among the most modern on the market. Bosch eBike rechargeable batteries combine low weight with ergonomic design and simple handling. The Battery Management System of the high-quality lithium-ion batteries detects potential sources of error and protects cells from overloading.
Bosch PowerTubes have the power to drive any ride and, thanks to their compact size and minimalist design, can be integrated with the eBike to ideal effect. There are two options for installing the battery: horizontal or vertical. New this year: PowerTube 400 and PowerTube 625. The sophisticated technology of the lithium-ion batteries that can be integrated within the frame ensures carefree riding enjoyment, while a safety catch prevents the battery from falling out even on challenging terrain. Nevertheless, the batteries can be removed with ease.
Advantages of Bosch PowerTube E-Bike batteries
Outstanding battery efficiency For maximum riding pleasure, lithium-ion PowerPacks demonstrably have maximum energy density with the smallest size and lowest weight on the market.
Simple to store and quick to charge Modern Bosch lithium-ion batteries do not suffer from memory effect or self-discharge issues. Your battery will charge to 50% in about 2 hours, depending on the charger and PowerPack.
Ergonomic handling It’s easy to remove and charge at home. The PowerPacks can also be conveniently charged directly on the bike.
No memory effect Bosch batteries with lithium-ion cells can be charged quickly irrespective of your charge level at any time. Interruptions of the charging process do not harm the battery. Complete discharge is not required.
Extremely low self-discharge Even after long periods of storage, e.g. over winter, the battery can be used without recharging. This means Bosch rechargeable batteries do not need to be recharged after a long break in use. For longer storage, a charge status of approx. 30 to 60% is recommended.
Long service life Bosch batteries are designed for lots of trips, miles and years of service. The intelligent, electronic Bosch Battery Management System (BMS) protects lithium-ion batteries from extreme temperatures, overcharging, and excessive discharge.
Bosch PowerTube 625
What more could you want? The PowerTube 625 lets you enjoy long and mountainous rides, while still reserving plenty of energy for every adventure. Thanks to a rated capacity of 17.4 Ah and approx. 625 Wh energy content, the lithium-ion battery brings maximum ranges and altitudes within your grasp. The well-secured PowerTube 625 will not fall out of its housing, even on demanding terrain. But is still easily removed.
