As Cardiff’s premier e-bike specialist, Damian Harris Cycles
has put together the definitive guide to why the 2027 Reaction Hybrid Pro 800 deserves a spot in your garage.
Unstoppable Power: Next-Gen Bosch Performance Line CX & 800Wh Battery
At the absolute core of the Cube Reaction Hybrid Pro 800 2027 is the brand-new, ultra-refined Bosch Performance Line CX Gen 5 motor. Delivering smooth, natural, and incredibly quiet power delivery, it turns the steepest fire road climbs into an absolute breeze.
• Colossal Range: The integrated 800Wh Bosch PowerTube battery ensures you have enough energy reserves for epic, all-day trail exploration without range anxiety.
• PowerMore Ready: Still want more? The frame is fully PowerMore-ready, meaning you can seamlessly mount a 250Wh bottle-cage style range extender to push your boundaries even further.
• Smart System Control: Managed by the ergonomic Bosch Purion 200 handlebar display, you get full color-coded metrics, seamless mode selection, and custom tuning via the Bosch eBike Flow app.
The 2027 Upgrade: Premium RockShox Front Suspension
The biggest news for the 2027 model year is its front-end evolution. Cube has swapped out the basic forks found on previous generations for the highly capable RockShox Recon Silver RL Air suspension fork.
Offering 120mm of plush, air-sprung travel (100mm on smaller frame sizes), this fork brings premium trail compliance to the Reaction Pro tier. It tracks precisely through technical singletrack, filters out heavy rock gardens, and can be fine-tuned perfectly to your exact rider weight.
Premium Components and Frame Versatility
Cube hasn't just focused on the electrics; the mechanical component spec on the Pro 800 is genuinely impressive for its £2,899.99 RRP retail price point.
• Shimano XT 12-Speed Drivetrain: Enjoy crisp, precise, and utterly reliable shifting using a premium Shimano XT rear derailleur paired with a massive gear range ideal for heavy-torque climbing.
• 4-Piston Hydraulic Disc Brakes: Stopping a powerful e-MTB safely requires serious braking power. Cube has fitted excellent Shimano 4-piston hydraulic brakes to give you total control on steep, wet descents.
• Factory Dropper Post: A remote dropper seatpost comes standard, allowing you to get the saddle instantly out of the way when the trails get steep and technical.
• Ultra-Wide Tyres: Highly capable 2.6-inch Schwalbe tyres provide a massive contact patch for maximum cornering grip and confidence on loose terrain.
Whether you prefer the clean lines of the standard cross-bar frame, the easier access of the Trapeze frame geometry, or the fully commuter-equipped FE (Fully Equipped) version featuring integrated mudguards, lights, and pannier racks—there is a 2027 Reaction Hybrid Pro 800 tailored exactly to your riding lifestyle
