Cube has done it again: the 2023 Cube Reaction Hybrid SLX 750 Electric Mountain Bike Black & Reflex redefines hybrid hardtail mountain bikes, all over again.

Few bikes are more versatile than a well-equipped hardtail. Add a high-capacity battery, versatile frame and sizing options and smooth fourth-generation bosch power to the mix, and you've got a bike that's capable of taking on just about any challenge. That's the Reaction Hybrid SLX: a bike for all reasons.With a high-capacity Bosch battery – now up to 750Wh, even for smaller frame sizes – and powerful fourth-generation, Smart System-equipped Bosch CX motor, you'll definitely notice the power.Agile Ride Geometry delivers confidence-inspiring handling, as you'd expect. There's an Easy Entry frame option, and a new S frame with 27.5in wheels, so everyone can find their ideal Reaction Hybrid. And, with internally routed cables including a stealth dropper post upgrade option, Cube's educed the need for maintenance so that you can just enjoy the ride.Cube added Fox's 34 AWL fork for comfort and powerful, four-piston Shimano hydraulic disc brakes for control. And finished off with Shimano's peerless XT 1x12 transmission, so the right gear is always at your fingertips. Put it all together, and it's everything you need for exploring above and beyond.
