The 2021 Cube Reaction Hybrid Pro 625 29 black'n'grey is a high-quality e-mountain bike, available for 2749 EUR. The model features a Superlite aluminium frame with Gravity Casting and Agile Ride Geometry, which offers a clean and modern look thanks to its internal cable routing and fully integrated battery. The frame is also equipped with mounting points for a kickstand, mudguards and a luggage rack. The bike’s total weight is 24 kg.
Braking performance is provided by Shimano hydraulic disc brakes (BR-MT200) with 180 mm discs at the front and rear. Gear changes are handled by the SRAM SX Eagle™ 12-speed system, which enables precise and reliable shifting. The shifter is an SRAM SX Eagle™ trigger with a single-click function.
The SR Suntour XCM34 coil fork, featuring a tapered head tube, a 15x110 mm axle, 100 mm of travel and a lockout function, ensures a comfortable ride on uneven terrain. The pedals are CUBE PP MTB models, which provide good grip and stability. The drivetrain is powered by an ACID E-Crank crankset with 38 teeth and a length of 175 mm, as well as a SRAM PG-1210 Eagle™ cassette (11-50T).
The handlebars are CUBE Rise Trail Bars with a width of 720 mm, complemented by CUBE Performance grips. The stem is a CUBE Performance Stem E-MTB with a diameter of 31.8 mm. The headset is an ACROS AZX-1030, which has zero-stack dimensions of 1 1/2" (ZS 56 mm) at both the top and bottom.
The rims are CUBE EX30 models with 32 spokes and tubeless-ready, fitted with Schwalbe Smart Sam tyres (Active, 2.60), which are known for their good grip and durability. The front hub is a Shimano HB-MT400-B (15 mm, Boost, Centre Lock) and the rear hub is a Shimano FH-TX505 (QR, Centre Lock).
The saddle is a Natural Fit Sequence model, mounted on a CUBE Performance seatpost with a diameter of 30.9 mm and a CUBE Varioclose saddle clamp (34.9 mm).
At the heart of the e-bike is the Bosch Performance CX Generation 4 motor, delivering 85 Nm of torque and 250 watts of power. The motor is powered by a Bosch PowerTube 625 battery and controlled via the Bosch Purion display, which enables simple and intuitive operation.
