Riders looking to aim their front wheel down the steepest, roughest tracks will find the Reactor fits the bill

  1. Smooth suspension paves the way for high-speed fun
  2. decent kit
  3. stout front end
  1. Bit of a drag on the hills
  2. takes effort to generate speed on flatter terrain

If you’re a rider that’s focused on shredding singletrack rather than bike parks, the Nukeproof Reactor Pro 290 Alloy is a superb mid-travel trail bike

  1. A little lightweight for burlier riders

Vital MTB


Trail Bike Hooligan: Nukeproof Reactor 275 RS Nukeproof's take on the short/mid-travel trail bike turns out to be very capable - and tons of fun to ride.

  1. Fun factor!
  2. Confidence-inspiring geometry
  3. Rear suspension is perfectly balanced small/big hits
  4. Lyrik Ultimate – plush and well controlled
  5. Versatile build options
  6. Flip Chip adjustability
  1. Average rear hub engagement
  2. Rims cause snakebites and had tubeless issues in test
  3. Can be a bit tricky finding the balance between front and rear suspension
  4. Could have a steeper seat tube angle
  5. Not the very best pedaling efficiency
  6. Finish is perfectible
