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 youre charging technical trails.
Crafted from hydroformed, triple-butted 6061 aluminium, the Reactor frame delivers the perfect balance of strength and responsiveness. To reduce unsprung mass, the seatstays are molded from carbon fibre, giving the rear suspension a smoother, more controlled feel. Every frame is available in 27.5 or 29 wheel options and includes a flip chip to switch between Trail and Rail geometry settings.
Built to reward every pedal stroke and every descent, the Reactor delivers that pure Nukeproof stoke on every ride.
Purchasing through a Cycle to Work scheme enables you to pay for the bike via salary sacrifice and make a great saving.
Most bikes* and accessories we offer can be purchased through the scheme - You can also purchase accessories, clothing and upgrades for your bike too.
We accept vouchers from most providers, with a preference for Green Commute Initiative https://www.greencommuteinitiative.uk/ or GoGeta https://www.gogeta.com/
If your company haven’t signed up to a scheme, its super easy and with the provider Green Commute Initiative it doesn’t require the company to sign up - So less admin and paperwork for a busy admin/accounts team!
For a full list of providers we accept vouchers for see details here https://cooksoncycles.co.uk/cycle-to-work/ If you can’t see your provider on our list, just drop the store an email and we can double check.
*Depending on the cycle to work provider we may not be able to offer full discount on sale bikes or accessories due to commissions charged by the scheme.
Spread the cost of your purchase with 0% finance on all bikes, accessories, and parts. Simply choose Klarna at checkout to view your interest-free options, available for up to 36 months.

Bike Build & Delivery
All our bikes are built in store and thoroughly inspected, before carefully packing back up for shipping. If you have selected our white glove delivery service, the bike will come to you ready to ride and the driver can help with some basic bike setup (Saddle height and suspension) at your doorstep. Please be aware if you haven’t selected our white glove delivery service the bike will require some assembly, which we recommend be carried out by an experienced mechanic. See assembly instructions here
