Nukeproof MegaWatt Side

The What (or should it be Watt) and Why?

Since 2009 the Nukeproof Mega has been on a journey of constant development to meet the evolving demands of our riding, customers, and athletes. From iteration to iteration of the Mega, we’ve always sought to optimise the design with incremental improvements using knowledge learned within our team and using the latest bike technology and manufacturing techniques to ensure our latest thoroughbred Enduro race bike, the V4 Mega was ahead of the curve. In recent years, however, there has notable absence in the Nukeproof range, a bike with a motor. Like them, love them, loathe them, we’re not here to debate the E-Bike game, we’re just sorry it’s taken Nukeproof so long to join the e-Bike game. This hasn’t been due to not wanting to play, but just wait for the timing to line up to get it right. We had to ensure the frame engineering, technology available, performance, and ongoing support for our customer riders were all in place.

The time is now, and we are excited and proud to introduce the Nukeproof MegaWatt., our first E-Bike…. Sorry, Not sorry.

Nukeproof MegaWatt Technical Information

Designed and developed alongside the V4 Mega, the MegaWatt frame was honed to perform using a battery and motor from the outset. As with all bikes branding the “Mega” name, it retains the descending characteristics that have taken 4 Enduro World Series crowns and numerous race wins. The MegaWatt frame features the latest expertise from Shimano in the form of their Steps EP8 drivetrain and battery technology. When choosing a motor/ battery partner Nukeproof’s top priority was to partner with the right specialist. A brand that could perform at the leading edge, whilst having the infrastructure in place to support customers during the years of ownership. The MegaWatt frame is packaged to maximise the performance of the Shimano EP8 Motor and battery. Crafted from hydroformed 6061 aluminum, the MegaWatt shares the DNA and some tubing with its Mega sibling but features some differences. The most notable is the all-new one-piece cast aluminum bottom bracket shell that was engineered to package the Shimano Steps EP8 Motor. The downtube is engineered to maximise both strength and rigidity, with optimised wall thicknesses to help reduce weight. All this whilst ensuring easy access to the battery via an access door to allow riders to remove the battery for charging, changing, or transporting the bike easily (with the added benefit of accessing the cables to root them easily). The EP8 drive train power delivery is fully customisable, with two stock settings available to the rider easily. For usability from the outset, we have tailored these to offer a “power mode” and a “range mode”, with torque settings curbed to ensure the MegaWatt feels ridable on all trails and in all conditions (see attached presentation for power settings).

A huge amount of R&D has gone into the Forged Aluminium motor case and downtube to ensure strength at a minimal weight

The MegaWatt is offered in a choice of three build specifications; Comp, Elite, or Factory (see below for more info on each). The Factory and Elite use a 630WH Shimano battery, with the comp using the 504WH Shimano battery. Both 630WH and 504WH battery will fit in all MegaWatt models, with a secure flip-able battery mount to allow riders to easily adjustable the mounts on the with minimal fuss. All bikes will come complete with a Shimano battery charger and accessories for on-bike and off-the-bike charging. Please see individual specs for full details.

Whilst the MegaWatt shares the race-proven geometry of the Nukeproof Mega, it does so in an all-new mixed wheel size platform. A 29” wheel up front to maximise rolling efficiency with a 27.5” wheel outback. This ensures the MegaWatt has the ability to whip around even the tightest of Alpine trail, whilst still inspiring confidence in the stability to attacking the roughest terrain. The 297 wheelbase retains a similar chainstay length figure to the Mega 290 mode (442mm Vs 440mm). The rear chainstays are finished with 3D molded chain protection to keep the frame fresh and silent allowing you to concentrate on nailing the trail ahead. The MegaWatt is offered in Size Small through to XXL with evenly spaced size splits for best fit. It also shares Nukeproof’s “saddle offset” philosophy with the Mega; Steeper seat angles offered on larger sizes to optimise the riding position and maximise comfort and efficiency.

Subtle differences to saddle angel across the sizes; Comp Medium (Concrete), Elite Large (Dk Grey), Factory XL (Green)

Nukeproof MegaWatt Action Shot 2

All models feature a custom-tuned rear shock with 170mm of rear travel to ensures that the MegaWatt is super supple of the top whilst remaining progressive and supportive through the rest of the travel. The Anti Squat too is optimised to create a bike that offers ultimate performance on the descends and then returns you back to the top efficiently for more. The new Mega also has a wide SAG range (30%-35%) to allow you; the rider to tune the characteristics of the bike to your preferences.

Suspension Leverage Curve

Nukeproof Megawatt Leverage Ratio

A Super supple beginning for small bump compliance with strong Mid-Stroke support for optimal cornering and pumping. The Mid-End of the stroke allows for more tuning options and a wide 30-35% range of usable SAG. Increased end-stroke leverage prevents the suspension from spiking. 22% overall progression with an average ratio of 2.6 (measured from SAG)

Anti Squat Curve

Nukeproof Megawatt Anti-Squat

Slightly lower anti Squat numbers than its Mega sibling at 99%. This helps to increase the performance of the suspension (We’re able to do this due to the climbing assistance on an E-Bike). Higher anti-Squat in the climbing gears, which drops off to (52%)  in the descending gears. The MegaWatt remains true to our belief that a low anti-squat, but good mid-stroke support is a winning combo for climbing traction. However, we believe that the Anti-Squat should never prevent the suspension from working well over rough terrain.

Anti Rise Curve

Nukeproof Megawatt Anti Rise

The MegaWatt has a balanced amount of Anti-Rise that tails off for bigger hits on the trail. This allows some squat in the suspension when breaking hard into a corner allowing the rider to maintain his/ her position. This allows the rider to put the pressure through the tyres and into the ground for excellent traction under hard breaking

Axle Path Curve

The MegaWatt axel path moves rearwards for 50mm (sag). This prevents the rear wheel from hooking up on square edges and ultimately will help the rider holds speed.

When will the Nukeproof MegaWatt be available to buy?

The MegaWatt Elite and Comp models will be available in stores from the 2nd July 2021. There will be three specifications of the bike available with factor models coming around the 5th of August 2021.
