Kilowatt 2026

The Kilowatt is Nukeproof's first eMTB built around DJI's Avinox drive unit, and it arrives with one clear mission: be the cheapest credible way into an Avinox bike. It is a mid-travel all-mountain machine, not a long-travel enduro sled (that job stays with the Megawatt) - 150 mm out back, a 160 mm fork, and forks on 35-36 mm stanchions that signal trail manners rather than bike-park brute force. Nukeproof's own brief was a bike "light enough to rip local trails" but capable enough for "a trip to the Alps", combining the confidence of the Mega with the more versatile, adventure-ready feel of the Reactor.

Value is the whole story

Avinox bikes are everywhere now, so Nukeproof's lever is price. The range opens at £3,999 / €4,499 for the Alloy Comp - and even that entry bike gets a full 800 Wh battery and an Avinox motor, undercutting a lot of Bosch- and Shimano-powered rivals that give you less power for more money. Avinox quotes up to twice the peak output of the 750 W Bosch CX, so the Kilowatt name (1,000 watts) actually undersells it.

Motor & battery

Three of the four builds use the flagship Avinox M2S: up to 150 Nm of torque and a 1,300 W peak, rising to 1,500 W in short Boost-mode bursts. The entry Alloy Comp steps down to the Avinox M2 (still a hefty 1,100 W, 125 Nm). Every size except the small carries the 800 Wh internal pack; the size S drops to 600 Wh because the shorter down tube won't take the bigger battery, which at least saves around 900 g. Nukeproof went non-removable on purpose - the goal was the cleanest possible frame so the bike looks and rides closer to its non-assisted bikes - so off-bike charging and battery swaps are out. The catch is mitigated on the carbon models, which ship with Avinox's 12 A fast charger (around 80% in roughly 90 minutes, enough for a meaningful lunch-stop top-up); the alloy bikes get a slower 4 A unit.

Frame & suspension

Both the alloy and carbon frames are all-new and designed in-house, and Nukeproof went to some lengths to make them look near-identical. The alloy frame, built with a manufacturing partner experienced in automotive casting, uses a one-piece cast section around the motor that ties the tubes, motor and suspension mounts together, plus intricately hydroformed tubes and asymmetric seat- and chainstays. It carries lessons from the Scout, Reactor and Mega. Suspension is Nukeproof's familiar four-bar Horst-link with a single-piece rocker for front-to-rear stiffness - a layout they have refined for over a decade, tuned for early small-bump traction with mid-stroke support for pushing hard. There's tube-in-tube internal routing, room for a bottle and a tool mount ahead of the shock, and a flip chip between the seatstay and rocker that switches between the standard MX (mullet) setup and a full 29in.

Geometry & fit

Geometry is firmly in aggressive-trail/enduro territory without going to extremes: a 64° head angle, a 77-77.5° effective seat angle (77° on S/M, 77.5° on L/XL) and 450 mm chainstays across every size. Reach runs 435-500 mm (S-XL) and wheelbases from 1,209 mm to 1,287 mm, which is fairly compact by current standards. Stack is on the short side (647 mm even on the XL), so taller riders or anyone who likes a high front end will want a riser bar or a few spacers. Claimed weight starts from 22.2 kg (medium) - not light by lightweight-eMTB standards, but competitive for a full-power bike with an 800 Wh battery, gravity tyres and a properly trail-ready build. Every model runs Schwalbe Gravity tyres and 155 mm cranks.

The builds

• Alloy Comp - £3,999 / €4,499: Avinox M2, RockShox Psylo Gold RC fork and Deluxe Select shock, SRAM S100 12-speed mechanical, SRAM DB4 brakes, Shimano TC500 / WTB STi30 wheels, 4 A charger. The value pick and the cheapest route to Avinox.
• Alloy Pro - £4,999 / €5,499: the M2S motor with RockShox Lyrik RC / Super Deluxe, SRAM Eagle 70 T-Type, Maven Base brakes and Nukeproof Neutron wheels - arguably the sweet spot before the carbon frames begin.
• Carbon Expert - £6,499 / €7,499: carbon frame, M2S, Fox 36 Performance (GRIP) and Float X, SRAM GX / Eagle 90, Maven Base brakes, DT Swiss HX1900 wheels and the 12 A fast charger.
• Carbon Factory - £7,999 / €8,999: the flagship - M2S, Fox Factory 36 and Float X, SRAM X0/GX AXS T-Type, Maven Silver brakes, DT Swiss HX1700 wheels, a OneUp V3 dropper and the 12 A charger.
