From concept to kinematics, geometry to spec, the Nukeproof Reactor was built from the ground up to be the ultimate aggressive trail bike. It climbs with precision but truly comes alive when you’re charging technical trails.

Constructed from a hydroformed and butted 6061 T6 aluminium alloy, with carbon fibre seat stays to reduce unsprung mass and optimise lateral stiffness. The Reactor delivers the perfect blend of low weight, strength, and stiffness.

Made for long days in the saddle, it’s your go-anywhere trail weapon—ready for epic adventures where a 1,000m climb leads to a 1,000m descent. Whatever the trail throws at you, the Reactor 290 Alloy is built to take it on.
