E-Bike Whistle B-Rush Carbon: Performance and Innovation for Trail and Technical Descents

The Whistle B-Rush Carbon is designed to tackle the most challenging climbs and dominate technical descents with speed, precision and fun. Designed for high-level competition, it offers ideal handling even on the local trails, thanks to a superior frame and suspension system.

29" Carbon Monocoque Frame with 150mm Travel

The carbon fiber frame of the Whistle B-Rush Carbon is designed to ensure maximum rigidity and steering precision, essential to manage the high power generated by both the cyclist and the engine. The monocoque structure, without joints such as glues or welding, allows for better distribution of forces, offering advantages in terms of weight and resistance.

Main features:

• Material: Carbon monocoque.
• Wheel size: 29".
• Suspension travel: 150 mm.
• Innovative Design: The carbon fiber is oriented to optimize stiffness and flexibility in critical points, reducing weight and improving vibration absorption capacity.

The result is a responsive, durable and high-performance frame, perfectly integrated with the carbon battery cover and engine guard.

Latest Generation Engine, Battery and Software

The B-Rush Carbon features the proven Bosch Performance Line CX motor with 85 Nm of torque, supported by the new 800 Wh Bosch battery, which offers greater range than the previous 750 Wh version.

The battery integration has been carefully considered to preserve the modern frame geometry and maintain high maneuverability.

What's new in the Bosch system:

• Engine: Bosch Performance Line CX with customizable riding modes and Extended Boost function for intuitive handling.
• Display: Bosch Purion 200, simple and complete, with the possibility of combining it with the Kiox 300 or Kiox 500 displays.
• Battery: Greater capacity for longer battery life.

Bosch Purion 200 Display: Essential and Flexible

The Bosch Purion 200 is a compact display that can be used as a remote control or integrated with other interfaces, ensuring total flexibility:

• Pairing with additional displays: Can be combined with the larger Kiox 300 and Kiox 500 displays.
• Smartphone compatibility: Allows you to use your phone as a screen via the Bosch app.

Improved “assisted walking” function:
By holding down the minus [-] button, the bike automatically pushes uphill; by releasing the button, the motor keeps the bike stationary for a few seconds, making it easier to handle on challenging terrain.

The Whistle B-Rush Carbon represents the meeting point between technological innovation and cutting-edge design. Perfect for those looking for high performance, this e-bike adapts to the needs of both the most demanding riders and those who want to have fun on local trails.
