Bosch Performance Line CX Motor
The Reaction Hybrid Race 800 uses Bosch’s Performance Line CX Smart System motor from the BDU38 family. Designed for demanding e-mountain bike riding, the mid-drive motor provides responsive support when tackling steep climbs, uneven ground and changing gradients.
Actual maximum available torque depends on the motor’s software configuration. The source retailer specifies up to 100 Nm, while CUBE’s current manufacturer specification lists a maximum capability of up to 120 Nm.
The Bosch Purion 200 display combines motor assistance controls and essential riding information in a compact handlebar-mounted unit.
800 Wh Battery & Riding Range
The Bosch PowerTube 800 battery provides 800 Wh of rated energy capacity and is neatly integrated into the bicycle’s aluminium frame.
A Bosch 4A charger is included in the listed standard specification. The frame is also PowerMore-ready, allowing a compatible Bosch PowerMore 250 range extender to be added separately.
Actual riding distance varies according to assistance mode, elevation, rider weight, temperature, tyre pressure and terrain. No fixed distance per charge is guaranteed.
SRAM Eagle 90 12-Speed Transmission
The CUBE Reaction Hybrid Race 800 features SRAM Eagle 90 Transmission with 12-speed mechanical shifting.
The wide-range SRAM XS-1270 10–52T cassette provides climbing-friendly gearing alongside ratios for faster sections and flatter terrain.
A SRAM GX Eagle Transmission chain and ACID MTB Hybrid Pro 38T crankset complete the drivetrain, supported by a dedicated chain guide.
RockShox Suspension & Trail Comfort
The RockShox Recon Silver RL Air fork provides suspension travel to absorb bumps and vibrations from uneven trails.
Frame sizes M through XXL use 120 mm of front suspension travel, while size S features a 100 mm configuration.
The air-sprung design allows suspension setup to be adjusted to the rider’s requirements, helping maintain comfort and control across suitable recreational mountain bike routes.
Magura Four-Piston Hydraulic Brakes
Magura Louise hydraulic disc brakes feature four-piston calipers at both wheels and large 203 mm rotors.
The braking system delivers controlled stopping performance across varied trail conditions, supporting rider confidence on descents and uneven surfaces.
Wheels, Tyres & Handling
The Reaction Hybrid Race 800 uses ACID Pro 30 tubeless-ready wheels with Schwalbe Smart Sam Active 2.6-inch tyres.
CUBE’s Size Split approach provides 27.5-inch wheels on size S and 29-inch wheels on sizes M through XXL.
Agile Ride Geometry is designed to balance responsive steering with stable handling, while the wide tyres offer useful grip on suitable recreational tracks and mixed surfaces.
Aluminium Superlite Frame
The frame uses Aluminium Superlite construction with Gravity Casting Technology, Boost148 rear spacing, an integrated battery and advanced internal cable routing.
The clean design features a CUBE Rise Trail Bar 35, ACID Hybrid Perform grips and an ACID Sequence 160 saddle.
A CUBE dropper seatpost with handlebar control allows the rider to change saddle height conveniently when moving between climbs and descents.
Accessory Compatibility
The frame includes mounting provisions for compatible mudguards, a luggage carrier and kickstand.
CUBE’s X-Connect interface allows a compatible ACID front light to be connected separately. Lighting, mudguards and a carrier are not included in the confirmed standard equipment.
The Bosch PowerMore 250 range extender is also an optional accessory rather than part of the supplied bicycle.
