The "Reaction Hybrid SLT 625 29 denim’n’iceblue" model from Cube, released in 2022, is a high-quality e-mountain bike designed for discerning riders. Priced at 3,999 EUR, it offers a wide range of advanced technical features and components.
The bike’s frame is made from Superlite aluminium and features Agile Ride Geometry, which ensures agile and safe handling. The frame is manufactured using a gravity casting process, which gives it additional stability. It also features a 1.5 headtube and Boost 148, which improve stiffness and control. The internal cable routing ensures a clean, tidy look and protects the cables from external damage. The frame is also fitted with mounts for a kickstand, mudguards and a luggage rack, which increases the bike’s versatility.
Braking performance is provided by Shimano XT BR-M8120 hydraulic disc brakes with 203 mm rotors at the front and rear, which operate reliably even at high speeds and in challenging conditions. The drivetrain consists of a Shimano XT RD-M8100-SGS ShadowPlus 12-speed rear derailleur, which is directly controlled by the Shimano XT SL-M8100-IR shifter. This combination ensures precise and rapid gear changes.
The Fox 34 Float AWL fork, with 120 mm of travel and optimised for e-bikes, offers excellent suspension performance. It is fitted with a 2-position Sweep-Adjust RAIL damper and features a tapered steerer tube and a 15x110 mm thru-axle.
The bike is fitted with CUBE PP MTB pedals, which provide a secure grip. The ACID E-Crank crankset, with a length of 175 mm and a 38-tooth chainring, together with the Shimano Deore CS-M6100 sprocket (10-51T) and the Shimano CN-M6100 chain ensure an efficient drivetrain.
The handlebars are a 720 mm wide CUBE Rise Trail Bar, combined with ACID React Pro grips and a CUBE Performance Stem E-MTB stem (31.8 mm). The headset is an ACROS AZX-1030, which uses Zero-Stack bearings (ZS 56 mm) at both the top and bottom.
The tyres are Schwalbe Smart Sam (2.6-inch), fitted to Newmen Performance 30 rims. These rims feature 28 spokes at the front and rear, as well as tubeless-ready functionality.
The saddle is a Natural Fit Sequence+, fitted to a CUBE Performance seatpost (30.9 mm) with a CUBE Varioclose seat clamp (34.9 mm).
The bike is powered by a Bosch Performance CX Generation 4 motor with 85 Nm of torque and an output of 250 watts. The battery is a Bosch PowerTube 625, which ensures sufficient range. The Bosch Kiox display provides all the necessary information whilst riding, and the Bosch 4A charger enables fast charging.
Overall, the Cube Reaction Hybrid SLT 625 29 denim’n’iceblue offers an impressive combination of performance, comfort and versatility, ideal for discerning e-mountain bike enthusiasts.
