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.

Advantages of the Bosch Performance Line CX engine

Outstanding motor control
The multi-sensor concept enables a dynamic and responsive drive unit for precise acceleration and a unique trail experience.

Direct power transmission
Powerful riding performance right from the start and constant power delivery over a very wide cadence range.

Natural riding sensation
The new gearbox concept significantly reduces pedalling resistance when the drive is switched off and at over 25 km/h.

Compact construction
Optimum integration thanks to a 48 % reduction in size and a weight of just 2.9 kg.

Complete control
eMTB mode with progressive motor support adapts to the riding style on trails.

Extremely robust
Meets the highest eMTB requirements and will withstand extreme loads.

Perfect combination
eMTB mode, powerful walk assistance and support for short cranks.

Precise acceleration
For a unique trail experience.

Efficient use of energy
Optimum efficiency of motor and gearbox in order to conquer long, steep climbs.

Always full performance
Ideal for fast intermediate sprints and crisp changes of tempo.

Low-noise
For low-noise riding with high engine power at all cadences.

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.
