Description

The Cube Kathmandu Hybrid SLX 800 is an electric trekking bike built for riders who cover real distances — commuting through town or heading out on unpaved paths — and expect high-end componentry throughout. The Bosch Performance Line CX (Gen 5) motor works in tandem with the Bosch PowerTube 800 Wh battery, which sits neatly inside the Superlite aluminium frame to keep the bike's profile clean and its centre of gravity low.

Where many e-bikes rely on basic drivetrains, the Kathmandu SLX 800 steps up with a full Shimano XT Di2 12-speed electronic groupset. Gear changes happen instantly with a light button press — no cable stretch, no missed shifts, even in wet conditions. Stopping power comes from Shimano XT hydraulic disc brakes, offering progressive, reliable modulation on any surface.

Comfort is engineered in at multiple points: the Fox 34 Float AWL fork (100 mm travel, e-bike optimised) soaks up rough ground at the front, while the suspended parallelogram seatpost cushions your lower back from repeated impacts. An adjustable stem and Cube's Efficient Comfort geometry make it straightforward to set up a position that works for your body. The Cube IC 3.0 integrated carrier means you can load up for the ride without adding a rack afterthought.

Available in sizes S, M, L and XL in foggrey´n´grey, the bike runs Schwalbe Marathon Efficiency tyres on Newmen Performance 30 29-inch wheels and is managed through a Bosch Kiox 500 display.

Bosch Gen 5 'Performance CX' - 120 Nm

The benchmark engine for riders who make no compromises. The 5th generation Bosch Performance Line CX is the trail engine par excellence: with 120 Nm of torque and assistance up to 25 km/h, it delivers raw and controlled power, capable of swallowing the most demanding slopes without ever flagging. Redesigned from the ground up, this 5th generation engine is more compact and lighter than its predecessors, while improving responsiveness. The response to pedaling is immediate and precise, with intelligent torque management that adapts to each variation in terrain - technical trails, steep climbs or chaotic paths, the CX knows no limit.

Bosch PowerTube 800 Wh

Uncompromising autonomy. The Bosch PowerTube 800 Wh is the battery that frees cyclists from the constraint of mileage. With 800 Wh of capacity, it pushes the limits of every outing — whether it's a long commute, a weekend getaway or a multi-day wilderness adventure. Integrated directly into the frame tube, the PowerTube disappears into the silhouette of the bike for a clean aesthetic and optimal protection against shocks and bad weather. Light for its capacity, it recharges quickly and pairs perfectly with all Bosch Smart System motors for intelligent energy management in real time.

Bosch Kiox 500

The screen for those who want to see everything. The Bosch Kiox 500 is the advanced version of the Kiox range — a larger, brighter and more comprehensive connected display, designed for cyclists who want to access all of their riding data without taking out their smartphone. Its enlarged display offers optimal readability in all conditions, whether in the middle of the forest or in full urban sunshine. Permanently connected to the eBike Flow app via Bluetooth, it centralizes navigation, performance data and customization of modes in one place. A clear interface, careful ergonomics and exemplary responsiveness - the Kiox 500 is the reference screen for long and demanding outings.

Shimano XT Di2 RD-M8260-SGS, 12-Speed, Electronic Shifting System

Electronic shifting conquers the trail. The Shimano A simple press of the button is enough for an instantaneous, silent and perfectly calibrated gear change, even in the middle of a recovery or on a chaotic section. The SGS (Super Extra Long) version offers the maximum screed capacity to cover the entire development range of the widest 12-speed cassettes. No more loose cables, no more misadjustments during outputs - the Di2 maintains absolute precision from the first to the last hour, without intervention. And thanks to Bosch eShift compatibility, it integrates natively into the Bosch VAE ecosystem for automatic gear changes based on cadence and terrain.

Fox 34 Float AWL, 2-Position Sweep-Adjust RAIL Damper, Tapered, 15x110mm, E-Bike Optimized, 100mm

The fork designed for city and road e-bikes. The Fox 34 Float AWL with RAIL Damper 2-position Sweep-Adjust shock absorber is a fork specially designed to meet the particular requirements of electric bicycles — higher mass, high torques, intensive use. With 100mm of travel, it is optimized for electric trekking bikes, electric gravel bikes and assisted urban bikes, where comfort and control take precedence over pure trail performance. The RAIL Damper system with 2-position Sweep-Adjust allows you to easily switch between a soft open position for uneven paths and a firmer position for smooth roads — a quick, intuitive adjustment that maximizes pedaling efficiency. The E-Bike Optimized designation means that the fork has been reinforced and recalibrated to support the additional weight and specific constraints of everyday e-bikes.

Shimano Deore CS-M6100, 10-51T

The transmission that opens all horizons. The Shimano Deore CS-M6100 cassette in 10-51T is the versatile reference for cyclists who want to cover as much ground as possible without ever being caught off guard. With an exceptionally wide development range - from the small chainring for the steepest climbs to the large one for full-speed descents - it adapts to all terrain profiles and all levels of practice. Designed for Shimano Deore 12-speed transmissions, it combines lightness, shifting precision and proven durability. The profiled teeth and optimized shift ramps guarantee smooth and quiet gear changes, even under load – a quality usually found on much higher-end groupsets.

BORDO™ 6200K/90 SH black ART 2
The ABUS BORDO™ 6200K/90 SH is a folding lock designed for cyclists who need genuine, insurer-recognised security. With an ABUS security rating of 13 out of 15, ART 2-star certification, and Sold Secure Gold Pedal Cycle approval, it meets the requirements of most bicycle insurance policies — a key consideration for anyone with a higher-value bike.
The lock bars are made from hardened steel, offering strong resistance to cutting and leverage attacks. Steel discs protect the rivets — typically a vulnerable point on folding locks — against saw attacks. The XPlus cylinder provides enhanced pick and copy resistance, and two keys are included in the box.
A 94 cm locking circumference and a 360°-rotating lock body give you the flexibility to secure your bike to posts, railings, bike racks, and other fixed structures with ease. The included SH frame bracket keeps the lock neatly on your bike and features a discreet compartment for a spare key.
Made in Germany, the BORDO 6200K weighs 1,320 g with a width of 67.5 mm — compact enough to carry daily, yet robust enough to stand up to determined theft attempts.
