CUBE Reaction Hybrid Pro 500 Review - Prices, Specs, Videos, Photos

Sep 2018

Price: $3399.00 | Model Year: 2018 Hardtail electric cross country mountain bike with nimble 2.6

Observations
  • Hardtail electric cross country mountain bike with nimble 2.6" plus sized tires, Boost hub spacing and a sturdy 15mm thru-axle on the front wheel, upgraded Alex rims with reinforcement eyelets

  • Only available in high-step, but the frame comes in six sizes and the smaller two offer 27.5" wheel size vs. 29" on the larger four, this scales the bikes appropriately, adds comfort, and optimizes rolling momentum

  • Beautiful motor and battery integration, the Bosch Performance Line CX is tipped up with two thin plastic skid plates and the PowerPack 500 is sunk into the downtube for optimal weight distribution

  • Compact Purion display panel isn't removable, doesn't swivel easily, and the buttons can be inconsistent, the centerdrive motor uses a 2.5x reduction gearing system which introduces some drag when pedaling unassisted or over 32km/h (20mph)

Highs
  • Great looks.

  • Excellent Bosch motor/battery.

  • E-MTB mode simplifies the ride.

Lows
  • No dropper post.

  • Tyres aren't tubeless ready.

Cube Reaction TM review

Apr 2018

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.
