2025 Cube Reaction Hybrid Race 800 Electric Mountain Bike - Lizard - Size XL

Season:2025

Brand:Cube

Code:808410411412lizardBLK

The Cube Reaction Hybrid Race 800 Electric Mountain Bike is built for riders who want maximum performance, extended range and trail-ready versatility. Powered by the Bosch Performance Line CX Smart System motor, this high-performance hardtail e-MTB delivers smooth, responsive assistance to tackle steep climbs, long rides and mixed terrain with confidence. The large 800Wh Bosch PowerTube battery provides outstanding range, with compatibility for the 250Wh PowerMore range extender for even longer adventures.

At its core is Cube’s lightweight yet robust Superlite aluminium frame, engineered with Agile Ride Geometry for a perfect balance of comfort, stability and control. Models equipped with the Bosch CX (BDU384Y) motor can now unlock enhanced performance via the Bosch eBike Flow App, boosting output to 100Nm torque, 750W peak power and up to 400% support.

Trail performance is further enhanced by the RockShox Recon air suspension fork with 120mm of travel (100mm on Easy Entry and smaller frame sizes), absorbing bumps while maintaining precise steering. The reliable Shimano 12-speed drivetrain (XT shifter with Deore rear derailleur) ensures crisp, dependable gear changes, while Shimano four-piston hydraulic disc brakes deliver powerful, consistent stopping power in all weather conditions.

Rolling on 2.6” Schwalbe Smart Sam tyres, the Reaction Hybrid Race 800 offers excellent grip, comfort and rolling efficiency on trails, gravel and tarmac alike. A hydraulic dropper seatpost improves control on descents, and integrated mounting points allow for mudguards, rear rack, lights and kickstand, making this e-mountain bike ideal for commuting, touring or trail riding.

Available in diamond, trapeze and low step-through frames, with Size Split wheel sizing (27.5” on smaller frames, 29” on larger), the Cube Reaction Hybrid Race 800 is a powerful, versatile electric mountain bike designed to go further, faster and with total confidence.
