Cube Reaction Hybrid Performance 600 E-MTB
The Cube Reaction Hybrid Performance 600 E-MTB is a hardtail electric mountain bike built for riders who want dependable Bosch power, straightforward Shimano shifting and all-round comfort for UK trail riding, leisure miles and mixed-surface use. With a Bosch Performance Line motor, Bosch Smart System support and a 600Wh battery, it is the kind of e-MTB that makes everyday off-road riding feel easier without becoming intimidating or over-specialised.
Why choose this product
- Bosch Performance Line power gives smooth pedal assistance for climbs, headwinds and longer rides.
- 600Wh battery capacity makes it better suited to regular leisure and trail use than many lower-capacity entry options.
- Hardtail layout keeps the bike simpler, easier to maintain and more efficient than a full-suspension alternative.
- Shimano Cues 9-speed gearing is easy to use and well matched to mixed-terrain riding.
- Wide 2.6in tyres and hydraulic disc brakes help boost confidence in variable UK conditions.
- Kickstand, mudguard and carrier mounting points make it more versatile than a pure trail-only e-MTB.
Who it’s for
This bike suits riders who want a capable electric hardtail for bridleways, forest tracks, canal paths, trail centres and everyday adventure riding. It makes sense for riders moving into e-MTBs for the first time, for returning cyclists who want more support on climbs, and for anyone who values a practical Bosch-powered hardtail over a more aggressive and expensive full-suspension setup.
It is also a strong fit if you want one bike that can cover leisure riding, light trail riding and utility-focused upgrades such as mudguards or a rack. It is less suited to riders chasing steep, technical descending performance or bike-park-style riding.
Real-world performance
Bosch support that feels easy to live with
The Performance Line motor with 75Nm torque gives this Cube e-MTB enough assistance to make climbs, longer routes and mixed terrain feel more manageable. It is paired with Bosch Smart System integration, a Purion 200 display remote and a 600Wh PowerTube battery, so the bike is positioned as a modern, practical e-bike rather than a basic entry model.
Comfortable hardtail handling
A hardtail electric mountain bike like this is often the smarter buy for general UK riding because it keeps the ride direct and efficient while still giving comfort where it matters. Cube pairs the frame with a suspension fork offering 120mm travel, or 100mm on smaller frame sizes, plus wide Schwalbe Smart Sam tyres to add control on rougher ground.
Simple gearing and dependable braking
Shimano Cues 9-speed gears are a sensible choice here because they focus on ease of use rather than over-complication. Shimano hydraulic disc brakes and the broad tyre footprint help the bike feel reassuring in wet or changeable weather, which matters for UK buyers using the bike year-round.
Useful beyond pure trail riding
This model is not just about off-road fun. The frame includes kickstand, mudguard and carrier mounting points plus a top-tube multi-tool mount, so it has more day-to-day versatility than many harder-edged mountain e-bikes.
Compatibility and sizing guidance
Check your preferred frame style and wheel format before buying. Cyclo Monster lists this model with a size split of 27.5 for size S and 29 for M, L, XL and XXL, and also lists Easy Entry sizing in 27.5 for S to XL.
Choosing the right Reaction Hybrid Performance 600 setup| Option | Best for | What to check | When to choose it |
|---|
| Classic frame | Riders wanting a standard hardtail e-MTB frame layout | Preferred fit, stand-over and wheel size by frame size | When you want the usual mountain bike frame style for trail and leisure riding |
| Easy Entry frame | Riders prioritising easier mounting and everyday accessibility | Whether you prefer lower stand-over and step-through practicality | When comfort and convenience matter as much as off-road versatility |
| 27.5 wheel format | Smaller frame sizes and riders wanting a more compact feel | Your frame size and ride preference | When you are buying a small frame or want a more manoeuvrable setup |
| 29 wheel format | Medium to extra-large sizes and riders wanting smoother rollover | Frame size and terrain preference | When you want better momentum and stability over mixed terrain |
Comparison
Reaction Hybrid Performance 600 vs Reaction Hybrid One 600
The Performance 600 sits above a simpler entry-level e-MTB approach and gives you a Bosch Performance Line motor with 75Nm, Shimano Cues gearing and a versatile hardtail platform. It is a better fit if you want a little more all-round capability without stepping into the higher-price Reaction Hybrid Pro range.
Hardtail e-MTB vs full-suspension e-MTB
A hardtail like this is the better choice if you want lower maintenance, cleaner efficiency and a lower overall entry point into electric mountain biking. A full-suspension e-MTB makes more sense only if your riding is more technical and descending-focused.
Performance 600 vs FE version
The FE version adds a more utility-ready setup for riders who want extra everyday practicality from the start. This standard E-MTB version makes more sense if your priority is a cleaner off-road-focused setup with the option to add accessories later.
Is it right for you?
Buy this bike if you want a Bosch-powered hardtail electric mountain bike that can cover leisure riding, trail use and practical everyday versatility without becoming overly specialist. It is a strong choice for riders who want support, comfort and a sensible specification package in one bike.
Do not buy it if you mainly ride steep, technical descents and need the extra control of a full-suspension e-MTB, or if you want a fully equipped commuter-style e-bike straight from the box rather than a trail-first setup.
Expert insight
For many UK riders, this kind of Bosch hardtail is the most useful type of e-MTB. It gives enough motor support and battery capacity to open up routes and reduce fatigue, while keeping the bike simpler and easier to live with than more expensive full-suspension models.
