The Cube Reaction Hybrid Pro 750 is a full-power electric hardtail built around Bosch’s Performance Line CX Gen 4 motor, delivering 85Nm of torque through the Smart System and drawing from a generous 750Wh fully integrated PowerTube battery. That pairing is the headline here: enough capacity for genuine all-day trail rides, with Cube quoting up to around 160 miles in the most economical assist mode. The lightweight Cube Aluminium Superlite frame keeps things composed on climbs, while a 120mm X-Fusion MIG32 Air fork with lockout takes the sting out of rough descents.
Reliable Shimano Deore 1×11 gearing and a wide 11-51T cassette cover steep gradients, and Shimano MT200 hydraulic discs with 180mm rotors handle stopping. Grippy 2.6in Schwalbe Smart Sam tyres on 29in wheels (27.5in on size S) round out a capable trail package available in five sizes.

- 120mm air fork with lockout for climbs
- Shimano Deore 1×11 drivetrain, 11-51T range
- 250W pedal-assist EAPC – UK road-legal
A Closer Look at the Cube Reaction Hybrid Pro 750
The headline spec here is the pairing of Bosch’s Performance Line CX Gen 4 motor — 85Nm through the Smart System — with a fully integrated 750Wh PowerTube battery, which Cube quotes as good for up to around 160 miles in the most economical assist mode. That’s a genuinely long range for a hardtail trail eMTB, enough for back-to-back all-day rides without needing a mid-route charge.
Cube’s Aluminium Superlite frame keeps weight in check for a battery this size, and a 120mm X-Fusion MIG32 Air fork with lockout takes the edge off rough descents while a firm platform for climbing is one lever-flick away. Shimano Deore 1×11 gearing with an 11-51T cassette covers steep gradients without a front derailleur to maintain, and grippy 2.6in Schwalbe Smart Sam tyres on 29in wheels (27.5in on the smallest size) round out a genuinely trail-capable package.
Who Rides the Reaction Hybrid Pro 750, and Where
This is a trail eMTB for riders who want a hardtail’s directness and lower maintenance compared to full suspension, combined with enough battery capacity for genuinely long trail days. Because assistance is pedal-only and limited to 15.5mph with no throttle, it’s a fully UK road-legal EAPC — you can ride it to the trailhead on the road and out onto the trail without needing separate road-legal and off-road bikes.
Setup & Care
The X-Fusion fork needs the same annual lower-leg service as any quality air fork, and the lockout lever should move freely — check it isn’t gummed up with trail dirt. Shimano’s 1×11 drivetrain benefits from regular chain cleaning given the wide 11-51T range under load. Charge the integrated 750Wh PowerTube per Bosch’s guidance, and given the tyre volume, check pressures to suit the terrain rather than running one setting for everything.
