Sleek Urban Electric Bike with Bosch SX Motor and Gates Belt Drive


The Cube Editor Hybrid SLT 400X Electric Bike in Smaragdgrey/Prism is a sleek, lightweight and low-maintenance urban electric bike designed for commuting, city riding and stylish everyday transport. Built around a clean aluminium frame with integrated cables, a hidden 400Wh battery and a lightweight full carbon fork, the Editor Hybrid SLT 400X has the understated look of a premium city bike with the smooth power of a modern e-bike.

Designed to fit seamlessly into busy urban life, this Cube electric hybrid bike combines a lightweight Bosch SX drive unit, integrated 400Wh battery, clean Gates belt drive, Shimano Alfine 11-speed hub gears and powerful Shimano Deore hydraulic disc brakes. It is the ideal choice for riders who want a refined, practical and efficient way to beat traffic and move through the city with ease.


Elegant Aluminium Frame with Integrated Design

The Cube Editor Hybrid SLT 400X frame is made from lightweight and durable aluminium, with Smooth Welding at the main tube joints for a clean, elegant and almost organic finish. Fully integrated cables keep the frame lines uncluttered, while the 400Wh battery is positioned neatly inside the down tube for a discreet e-bike appearance.

Cube has also integrated the mini controller into the top tube, giving the bike a streamlined cockpit and helping preserve its minimalist urban style.


Lightweight Bosch SX Drive and 400Wh Battery

Powered by Bosch’s lightweight SX drive unit, the Editor Hybrid SLT 400X delivers smooth and natural pedal assistance for everyday riding. Whether you are commuting to work, crossing town or riding between appointments, the Bosch SX motor gives you efficient support without compromising the bike’s agile feel.

The built-in 400Wh battery provides practical range for urban journeys while keeping weight and bulk low, making this e-bike a smart solution for riders who want electric assistance in a sleek, understated package.


Gates Belt Drive and Shimano Alfine 11-Speed Hub Gear

The low-maintenance Gates belt drive keeps the drivetrain clean, quiet and easy to live with. Unlike a traditional chain, the belt drive requires less regular cleaning and is ideal for year-round city riding.

Paired with Shimano Alfine 11-speed internal hub gears, the Editor Hybrid SLT 400X offers smooth, reliable shifting with a wide gear range for urban routes, hills and everyday commuting. This setup is perfect for riders who want get-on-and-go simplicity with minimal maintenance.


Confident Braking and Fast-Rolling Urban Tyres

Powerful Shimano Deore hydraulic disc brakes provide dependable stopping power in all weather conditions, helping keep you in control through traffic, wet roads and busy city streets.

Wide Schwalbe Marathon Efficiency Evo 50mm tyres deliver a confident balance of comfort, grip and fast rolling performance, making the bike ideal for city roads, cycle paths and rougher urban surfaces.
