Description

The Cube Supreme RT Hybrid Comfort EX 600 is an electric city and trekking bike built for daily use on urban streets and light trails. The Easy Entry step-through frame in Superlite aluminium (heat-treated 6061) lets you mount and dismount without swinging a leg over a high top tube — a small detail that makes a real difference when you stop frequently throughout the day.

The Bosch Performance Line motor (75 Nm) delivers a smooth, responsive boost when pulling away from traffic lights or tackling inclines. The Bosch PowerTube 600 Wh battery sits neatly inside the frame, keeping the bike's profile clean and its weight centred low. Ride data is displayed on the compact Bosch Purion 200 handlebar display.

Shifting is handled by a Shimano Nexus 5-speed internal hub — a fully enclosed system that needs virtually no maintenance and works cleanly in rain, mud, or cold. The SR Suntour NEX-E25 suspension fork (50 mm travel) takes the edge off cobblestones and rougher surfaces, and the suspension seatpost does the same for bumps transmitted from the rear.

The bike ships complete with full mudguards, a semi-integrated rear rack, front and rear lights, and a kickstand — everything you need for commuting or leisure riding. Maximum system load is 140 kg. Available in sizes XS to L, with 26" wheels on the 42 cm frame and 28" wheels on larger sizes.

Bosch Performance Line Gen 4 - 75 Nm

The accessible reference for electrical assistance without a false note. The 4th generation Bosch Performance Line with its 75 Nm of torque offers a smooth and balanced driving experience, designed for those who want to enjoy the electric bike on a daily basis without seeking performance at all costs. Compact and discreet, this engine integrates naturally into the frame and is forgotten while riding — until the moment you need it. The assistance is then there, direct and linear, to support your effort on flat sections as well as on slight urban climbs.

Bosch PowerTube 600 Wh

The perfect balance between autonomy and lightness. The Bosch PowerTube 600 Wh is aimed at cyclists looking for a high-performance battery without unnecessarily weighing down their bike. With 600 Wh of capacity, it largely covers the needs of everyday life and medium-distance outings, while maintaining a contained weight which preserves agility and driving pleasure. Like the entire PowerTube range, it fits discreetly into the frame tube, providing a clean profile and natural protection against impact and the elements. Coupled with Bosch Smart System motors, it benefits from intelligent energy management which adapts consumption in real time to maximize each kilometer traveled.

Bosch Purion 200

The main thing, without distraction. The Bosch Purion 200 is the control screen designed for cyclists who want to keep their eyes on the road. Compact and integrated directly into the handlebars, it combines control and display in a single unit — clean, readable and perfectly within reach. Its clear display shows essential information at a glance: assistance level, speed, remaining autonomy and battery status. No frills, no extras — just what you need to ride with confidence. Robust and weather-resistant, it faithfully accompanies every outing, whatever the weather.
