Nukeproof’s Megawatt e-MTB is like a Mega but with extra watts


Nukeproof launched the Megawatt, an electrified version of its EWS-winning Nukeproof Mega enduro bike.

The Megawatt has a Mullet configuration of mixed wheel sizes, 170mm of travel front and rear, is powered by Shimano’s EP8 motor, and has an aluminum construction.

Three models will be offered in five sizes, with prices starting at under £ 5,000, full details of the build specifications are listed below.

Nukeproof says the bike is good for all-mountain, enduro and DH type riding.

A mega lineage

The original Mega was launched in 2009 and is named after France’s famous Megavalanche race – which sees thousands of runners stacking a glacier high in the Alps before tackling a brutally technical singletrack as the race emerges into the village of Alp d’Huez in the valley below. often after 40 minutes of intense running.

Over the years the Mega has racked up many racing successes, most notably under Sam Hill, who won three EWS seasons aboard various iterations of the bike.

With the growing popularity of electric mountain bikes over the past five years, Nukeproof was one of the few brands that did not offer an electric mountain bike until now.

True to form, Nukeproof wanted to keep its electric megawatt (see what they did there?) In line with its heritage, and so the bike’s shape had to be as close to aluminum as possible, without Mega – and the non-powered version and Megawatt were designed together.

Nukeproof Megawatt Frame Design

In terms of aesthetics, this meant that the frame had to be “clean, simple and functional” with fairly square profile tubes and parallel seatstays and top tubes.

Likewise, the junction of the head tube and down tube had to be recognizable by Nukeproof, as was the swinglink of the shock absorber that wraps around the seat tube.

Elements of the V2 Mega can be seen in the rear triangle, although the shapes have been modernized by softening some lines and accentuating others, according to Nukeproof.

Other tubes are straight, with minimal bends and bumps, while tube length and diameter ratios have been taken into account to ensure the bike performs aesthetically and functionally.

Motor and battery integration

Shimano’s EP8 is bolted into the belly of the megawatt, with the battery hidden in the down tube – either the 504Wh or the 630Wh will be installed, depending on the bike’s build specifications. It is accessed through a door at the base of the tube.

The battery is housed in a one-piece molded motor housing, while the down tube shape is designed to give the necessary strength and stiffness, while still allowing accessibility of the battery.

Nukeproof has adjusted the engine power curves, giving riders two power profiles to choose from: power and range.

In the Power profile, the Assist Character, Max Torque, and Assist Start settings are all one or two levels higher than in the Range profile.

This should give it a more aggressive feel under the pedals in all three power modes (Eco, Trail, Boost). As you might expect, in Range the bike should be a bit quieter, but the battery life is extended.

Nukeproof Megawatt Geometry

Five megawatt sizes will be offered, from Small to XXL, so virtually any rider should be able to squeeze in on a bike, especially with its smaller 27.5-inch rear wheel, which means less grinding time on the slopes. for cyclists with shorter legs.

Nukeproof says there should be a bike for riders from 5ft 2in / 159cm up to 6ft 7in / 201cm.

Nukeproof is one of the many brands that seriously consider saddle height for each size of bike and adjust geometry to ensure taller riders don’t have their weight too far behind. This can be a problem for taller riders because when you raise the saddle, the effective seat angle decreases.

Nukeproof calls this the saddle offset, and it impacts the actual angle of the seat tube. The Vitus Scarp and Summit as well as the e-Summit also use this approach.

The geometry of the Megawatt is, as you would expect, very current, with a long, low and loose front end. The rear triangle does not change in size between frame sizes, and the wheelbases are designed to be very similar to the 29er Mega.

The key geometric figures for a Large are:

  • Reach: 475mm
  • Head angle: 64 degrees
  • Seat angle: 78 degrees
  • Seat offset (XS / L / XXL): 139.98mm / 163.32mm / 194.35mm
  • Base length: 442mm
  • Wheelbase: 1,288 mm
  • Bottom bracket height: 345mm

The 170mm rear wheel travel is provided by a four-bar Horst linkage, with a swivel link driving the shock absorber into the top tube.

The axle’s initial path is rearward, to about the sag point, which should help smooth the ride and reduce the amount of wheel hooks on the square edges.

Nukeproof aimed for a soft suspension at the start, to increase grip and comfort, before offering mid-race support.

At the end of the race, the progressiveness of the kinematics recedes, allowing better adjustment of the pilot with the volume spacers of the pneumatic shock absorber.

The projected sag range is 30-35 per center, so riders have a wide enough adjustment range to meet their preferences.

The leverage on the shock would be very similar to that of the Mega, with an increase of 22% throughout the race and an average ratio of 2.6.

In terms of anti-squat, in lower gears it is higher but still lower than an unpowered Mega, as the motor should compensate for this loss of pedal efficiency. This is done to increase flexibility and grip when climbing.

In higher gears, the anti-squat is weak enough, to reduce the impact of shock on the cranks – essentially reducing pedal rebound – for a smoother ride.

Likewise, when it comes to anti-lift, there is some squat under normal braking loads when the suspension is at mid-travel, to help the rear tire sink in, but this decreases on the longer ones. big bangs, allowing the rear to perform as it should in all conditions.

Nukeproof Megawatt frame details

The Megawatt has a number of beautiful finishes.

These include SRAM’s universal derailleur hanger, room for a 500ml bottle (or 620ml with an adapter), a rubber frame protector reinforced with a hard plastic shroud for the motor, a derailleur hanger. gear attachment and a collet-style main pivot pin, which Nukeproof says improves frame stiffness.

Cable routing is mostly internal, while the seat tube has been designed to allow maximum seat post insertion. There is clearance for tires up to 2.6 inches.
