German bicycle manufacturer Cube has introduced its latest electric bike aimed at urban riders, the Supreme RT Hybrid Comfort Exc 625, equipped with a Bosch motor and a suite of features designed for commuting and light trail use.
The new step-through e-bike is fitted with a Bosch Performance Line mid-drive motor, delivering up to 75 Nm of torque. The motor is part of Bosch’s smart system platform and is paired with a 625 Wh PowerTube battery that is fully integrated into the frame but removable for convenient indoor charging. A Kiox 500 display, which is 40% larger than its predecessor and rated for water and dust resistance, completes the Bosch system.
Designed specifically for urban environments, the Supreme RT Hybrid Comfort comes with Conti Contact Urban tires, known for their strong puncture protection—particularly useful in city settings where road debris is common. The bike also includes both Shimano hydraulic disc brakes on the front and rear and a coaster brake via a Shimano Nexus SL five-speed hub gear, offering multiple braking options for diverse riding situations.
The 28.5-kg bike is built with rider comfort in mind, incorporating a suspension fork with 50 mm of travel, a suspension seatpost, full mudguards, a semi-integrated rear luggage rack, and a kickstand. Cube says these additions aim to provide both utility and smooth performance over city streets and maintained trails.
The Cube Supreme RT Hybrid Comfort Exc 625 is now available at a retail price of £2,899 in the UK and €3,150 across European markets.
