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
Superb balance, insanely fast singletrack shredder
A little lightweight for burlier riders

Recently re-launched and now a full time member of the Nukeproof Reactor family, the Reactor 290 ST is a shorter travel version of the full suspension trail bike. With a lithe and resposive feel and top spec components, this bike – so long as you're happy to lock out the shock for climbing – makes a mean mile muncher. Merida One-Forty 600 review Vitus Mythique 29 VRS review The best ways to find new mountain bike trails As a 125mm full suspension trail bike, the Reactor 290 ST was designed for legendary downhill and enduro racer Sam Hill to ride in the off-season.

Nukeproof's take on the short/mid-travel trail bike turns out to be very capable - and tons of fun to ride.

Jan 2020
The Reactor feels like a bike with classic, old school all-mountain intentions, constructed with the colloquialisms of the contemporary mountain bike.

Nov 2019 · Mike Kazimer
Nukeproof's newest trail bike is built to handle just about any type of terrain.
Solid, ready for anything feel
Well equipped for the price and its intentions
Doesn't feel much different than an enduro bike
Seat tube angle could be steeper
Cable routing isn't fully refined
Doesn't feel much different than an enduro bike
