Summary
The CUBE Reaction trail bike series offers a mix of performance and value, with models praised for their acceleration, climbing efficiency, and component quality. However, some reviews note a harsh ride on descents, limited mud clearance, and tyres that struggle in wet conditions. The bike is often compared to the Specialized Epic Hardtail and Canyon Exceed CF SL 7.0 for its trail capabilities.
Instant acceleration
Impressive spec with well-chosen components
Great for sprinting up short, sharp climbs
Fox 34 fork is decently stiff with a supple GRIP damper
Cracking value for the price
Harsh ride on descents and rough trails
Tyres are thin and need higher pressures, adding to a jarring ride
Limited mud clearance
Tyres struggle in wet conditions
Long stem slows reactions on tight tracks
Snappy out of the gate, the Reaction has a powerful kick
It's cracking value and much more capable in the rough than the rest of the range if you like hacking about in the woods
Cube has a reputation for well priced bikes – you get a decent amount of bike for your money.

Fast reactions to pedal inputs help on climbs, but the stiff chassis affects descending capability
Instant acceleration
Impressive spec, with well-chosen components across the board
Harsh ride chokes descending speed and rough-trail acceleration
Tyres are thin and need higher pressures to prevent punctures, adding to the uncompromising ride feel

Cube's Reaction TM is a harder hitting version of their high-value aluminium Reaction hardtail range, pairing a sturdy 130mm fork up front with fat 2.6" tyres on 27.5" wheels. It's cracking value and much more capable in the rough than the rest of the range if you like hacking about in the woods, but there are harder edged weapons out there if you want to go full gonzo.
