The Cube Kathmandu Hybrid C:62 Pro 400X in spectralblue'n'prism represents a bold shift in e-bike design, moving away from the heavy, "tank-like" builds of traditional touring e-bikes toward a lightweight, agile, and high-performance carbon machine. By utilizing Cube's premium C:62 carbon for both the frame and the rigid fork, this bike weighs in at a remarkably low 18.3 kg—significantly lighter than its alloy counterparts. The "spectralblue'n'prism" finish is a high-tech metallic blue that features a prismatic flake, causing the colour to shift and sparkle under direct sunlight.
Central to this "lightweight" philosophy is the Bosch Performance Line SX motor. Unlike the bulky CX motors found on heavy commuters, the SX unit is compact and tuned for a sporty, natural ride feel with 60Nm of torque. It is paired with a 400Wh CompactTube battery, striking the perfect balance between keeping the bike nimble and providing ample range for cross-city commutes or light weekend touring. Integrated for the 2025/2026 season is the Shimano CUES 1x11 drivetrain, bringing the legendary durability of Linkglide technology to the electric touring world.

Key Highlights
Lightweight C:62 Carbon Construction: Traditionally, "Kathmandu" meant a heavy aluminum tourer. This C:62 version is a game-changer, offering a responsive, "carbon-bike" handling experience that is much easier to lift onto racks or maneuver through urban tight spots.
Bosch Performance SX Motor: This motor is designed for riders who still want to feel like they are cycling. It provides a 1:1 assist ratio that feels incredibly natural, with up to 600W of peak power available when you pedal at a higher cadence.
Integrated Utility (IC 3.0): Despite the carbon frame, the bike is fully touring-ready. The Integrated Carrier 3.0 is structurally part of the frame for maximum stiffness, and the bike comes standard with an ACID lighting system, full mudguards, and a kickstand.
- Purion 200 Smart System: The cockpit is incredibly clean thanks to the Purion 200 unit, which combines a high-resolution colour screen with the control buttons in one compact thumb-operated device on the left handlebar.
