The Cube Kathmandu Hybrid C:62 SLX 400X in liquidblack’n’bluedust is a masterpiece of lightweight e-touring engineering. Unlike traditional heavy-duty hybrids, the SLX utilizes Cube’s premium C:62 carbon fibre for both the frame and the rigid fork, bringing the total weight down to a remarkable 17.0 kg. The "liquidblack" finish provides a sophisticated, glossy aesthetic, while the "bluedust" adds a subtle metallic shimmer that reveals its depth under sunlight.
This model is built around the Bosch Performance Line SX motor, which delivers up to 60Nm of torque and 600W of peak power in a compact, 2kg package. It is specifically designed for a sporty, natural pedalling feel that rewards rider input. Paired with the integrated 400Wh CompactTube battery and the high-resolution Kiox 500 display, this bike offers a smart, connected riding experience that excels in urban environments and on long-distance light-touring adventures.

Key Highlights
Performance Line SX Motor: This motor provides a significant reduction in pedal resistance (over 50% compared to the CX line). It’s almost silent and works harmoniously with the rider’s cadence to provide a "natural" boost rather than a surge of power.
Shimano XT 12-Speed Drivetrain: The inclusion of XT-level shifting components ensures lightning-fast, precise gear changes. The 10-51T cassette provides a massive range, making even the steepest mountain passes manageable.
Kiox 500 Cockpit: The centrally mounted Kiox 500 offers turn-by-turn navigation via the Bosch eBike Flow app. It also features a "Sprint Mode" that helps you maximize the motor's power output during high-cadence bursts.
Newmen Beskar Wheels & Aerothan Tubes: Every gram counts on the SLX. By using Newmen’s lightweight Beskar 30 wheels and Schwalbe’s revolutionary Aerothan tubes, Cube has drastically reduced the "unsprung" and rotational mass, making the bike feel incredibly snappy.
Integrated Utility: Despite its racing-spec components, it remains a true Kathmandu. It features the Integrated Carrier 3.0, a powerful 150-lux ACID front light, full mudguards, and a kickstand, all seamlessly integrated into the carbon frame.
