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

The Reactor ST isn't as fast as some uphill, but it’s a proper demon when pointed back down
Surefooted downhill demon
Great spec at a reasonable price
Good geometry and ride position
Easy going but not as efficient as some uphill
Only slightly lighter than the top-spec Reactor which has more travel and a burlier build

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.

We take a look at the 2021 Reactor trail bike offering from Nukeproof, including a new higher spec aluminium build and the Reactor ST.

Oct 2020 · Nukeproof
Designed as the ultimate hard-charging hooligan of a trail bike and conceived for those riders that are looking for ultimate speed and style out on the trails, the RS is slightly over-forked, featuring +10mm of travel up front over the rest of the range to excel when on the most technical and mini enduros and downhill trails. .

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

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