Cube Reaction Hybrid ONE 720 2027
Reaction - Urban and off road capable
The CUBE Reaction Hybrid ONE is a versatile electric hardtail built to take everyday rides and off-road adventures further. Its carefully designed frame houses a 720Wh Bosch PowerTube battery and the Bosch Performance Line CX Smart System motor, delivering smooth, responsive assistance across climbs, trails and longer-distance routes.
Shimano Deore 1x12-speed gearing provides a wide range of reliable, easy shifting, while the air-sprung suspension fork improves comfort and control on mixed terrain. Most frame sizes feature 120mm of travel, with 100mm on smaller sizes and Easy Entry models. Powerful Shimano hydraulic disc brakes and wide 2.6in Schwalbe Smart Sam tyres provide dependable grip and confident braking in changing conditions.

Bosch PowerTube 720Wh Battery
An integrated Bosch PowerTube 720Wh battery provides the capacity required for longer rides and sustained climbing. Its position within the down tube maintains the bike’s clean appearance while helping to keep the additional weight central within the frame.
Actual range will vary depending on the selected assistance mode, terrain, elevation, rider weight and riding conditions. The 720Wh capacity gives riders the flexibility to cover longer distances without having to limit motor support throughout the entire ride.

Bosch Purion 200
The Bosch Purion 200 combines a compact colour display and system controller in a single handlebar-mounted unit. It presents important information including speed, battery charge, assistance mode, estimated range and ride data within the rider’s field of vision.
Its buttons sit within easy reach of the rider’s thumb, allowing assistance modes and display functions to be controlled without removing a hand from the handlebar. This keeps the cockpit simple while providing direct access to the Bosch Smart System’s main functions.
Connection with the Bosch eBike Flow app enables compatible system updates, ride recording and personalisation features.

Cube Reaction Hybrid ONE 720 2027 - in depth
The versatile and rugged Reaction Hybrid One is built around Bosch's quiet, powerful Performance motor with 75Nm torque. It's Bosch Smart System-equipped and fitted with a 720Wh battery for miles of pedal assistance. There's a clever flat mount for an optional kickstand and a mounting point for a multi-tool under the top tube. The Internal Cable Routing plus an innovative speed sensor setup flatter the frame's clean lines, and we built in our X-Connect system to make it easy to add a compatible ACID front light just by plugging it in. And, with Size Split, it's simple to find the perfect fit for you.
