Bosch Performance CX Motor: Powering Haibike and Cube’s 2025 E-MTB Innovations

The world of electric mountain bikes (e-MTBs) continues to evolve at a rapid pace, with motor technology taking centre stage in enhancing rider performance and experience. One standout in this field is the Bosch Performance CX motor, which powers some of the most innovative models in the 2025 e-MTB ranges from renowned brands like Haibike and Cube. Known for their commitment to premium quality and performance, these brands have embraced Bosch’s cutting-edge motor technology to push the limits of what riders can achieve on both rugged terrains and smoother trails.

Bosch Performance CX (Gen5): A Technological Leap Forward

The Bosch Performance CX motor is a powerhouse of e-MTB technology, and the latest Generation 5 (Gen5) model brings with it significant improvements that set it apart from previous versions. Here’s a breakdown of the key features and specifications:

• 85 Nm of torque: Offering an immense amount of power, the 85 Nm torque allows riders to conquer even the steepest of hills and tackle technical terrain with ease. Whether you’re an experienced mountain biker or new to e-MTBs, this added torque can make the difference when navigating tough climbs.
• Improved noise control: One common issue with older e-MTB motors has been the noise, but Bosch has made significant strides in reducing motor noise and rattle. The Gen5 CX is much quieter, ensuring a more immersive and less disruptive riding experience.
• Hill Start feature: A standout new feature, Hill Start allows riders to restart on steep inclines without worrying about rolling backwards. This innovation provides greater confidence and control, particularly on challenging terrains where stopping and restarting can often be a struggle.
• Extended motor overrun: In demanding conditions like steep or technical climbs, the extended overrun feature ensures power continues to flow even as the terrain becomes more difficult, helping riders maintain momentum when they need it most.

To better understand the improvements from previous models, here’s a comparison of Gen4 and Gen5:

Haibike’s 2025 E-MTB Models Powered by Bosch

Haibike has long been a pioneer in the world of e-MTBs, and for the Haibike 2025 range, they’ve once again pushed the envelope by integrating Bosch’s Performance CX motor into their latest models. These bikes are designed with all-mountain and enduro riders in mind, perfect for those who love tackling rugged terrains with the power of electric assistance.

• Key Model: The Haibike AllMtn range, one of Haibike’s flagship models, is a prime example of the brand’s commitment to pushing boundaries. The added torque and extended motor overrun of the Bosch CX motor allow for even greater control and power during challenging climbs. For riders who love the thrill of extreme terrains, the AllMtn range offers an unrivalled e-MTB experience.
• Benefits for Riders: The Bosch Performance CX motor doesn’t just offer power – it offers a level of customisation through the Bosch Smart System, allowing riders to tweak the motor’s performance to suit their specific riding style and terrain. This means better energy management and maximised efficiency for those long mountain rides.

Cube’s 2025 Models Leveraging Bosch Technology

Cube’s 2025 e-MTB range has also embraced the Bosch Performance CX motor, catering to riders who seek a versatile bike that excels on both technical trails and smoother paths. Cube’s approach to e-MTBs is about offering a balance between agility and power, making their models highly adaptable to varying terrains.

• Key Model: The Cube Stereo Hybrid series has become a favourite among e-MTB riders, and the integration of the Bosch CX motor has only enhanced its capabilities. This model offers a lightweight design combined with Bosch-assisted stability, ensuring that riders feel in control whether they’re on rocky paths or smooth inclines.
• Enhanced Range and Efficiency: One of the standout benefits of Bosch’s Gen5 CX motor in Cube’s models is the improved battery efficiency. Riders can now enjoy extended rides without the need for frequent recharging, making it a perfect choice for adventurers who love long, uninterrupted journeys.

Bosch CX vs. Competitor Motors: The Shimano EP8 Comparison

In the competitive world of e-MTB motors, Bosch’s Performance CX Gen5 goes head-to-head with another popular motor, the Shimano EP8. While both motors are top-of-the-line, Bosch comes out ahead in several key areas, especially when it comes to power delivery and torque on inclines.

• Torque: Both motors offer 85 Nm of torque, but Bosch’s delivery of that power, particularly on steep climbs, tends to feel more robust and consistent compared to the EP8.
• Weight and Noise Levels: Bosch’s Gen5 CX motor is lighter than its previous models and boasts quieter operation than the Shimano EP8, giving it an edge in terms of rider comfort and bike handling.
• Smart System Integration: Where Bosch really shines is in its advanced smart system integration, which offers more customisation options and a more seamless user experience compared to Shimano’s EP8.

Here’s a side-by-side comparison of the two:
