Nukeproof took their time to come out with their first electric mountain bike. Their debut eMTB has been in development for a long time, and it's called the Megawatt.
The Mega platform is one of the brand's most iconic models and has been around since 2009; the Megawatt shares a lot with the V4 Mega released last year. Unlike the longer-travel Giga, it uses a Horst-link layout with a top-tube mounted rocker link to deliver 165mm of rear wheel travel, along with a 170mm fork. Unlike the Mega, which is available with a pair of 27.5" or a pair of 29" wheels, the Megawatt is mullet only, with a 27.5" rear wheel helping to keep the chainstays reasonably short.

nukeproof.com/ There are three different models, with prices ranging from $5,499.99 to $7,499.99 USD. All three have aluminum frames and use Shimano's latest EP8 motor. While the base model makes do with a 504Wh battery, the other two have 630Wh to play with.
Frame DetailsNukeproof just managed to make room for a small water bottle between the portly downtube and shock, which is a great thing in my book. There's another pair of bosses under the top tube for extra storage.
The cables are routed through the headset - something we're seeing more often lately. I'm not sure I like the idea of having to slightly take apart the headset to install cables (as if internal cable and brake routing wasn't enough of a faff). It doesn't rattle though.
The battery can be quickly installed and removed through the bottom of the down tube.
SuspensionThe Megawatt's suspension closely resembles the
meat-powered Mega, and that's no bad thing. While the leverage curve on older versions of the Mega had a high leverage ratio in the middle of the travel, creating a lot of mid-travel wallow, the new Mega and Megawatt share a more progressive layout, so the suspension stiffness (relative to the shock) increases throughout the travel. The Megawatt is slightly more progressive than the non-motorized Mega, with 21% change in leverage ratio from start to finish, compared to 17% for the traditional bike.
With the Float X2 shock, this gives the Megawatt a very supple beginning to the stroke with support building smoothly after sag.
Anti-squat is slightly on the lower side, though this is typical for an ebike. It has just under 100% anti-squat at sag in the 50-tooth gear but lower values in the smaller sprockets, dropping to around 50% in the 10t cog. That means if you stamp on the pedals it will bob a little, but it stays level when the motor is doing most of the work. That's because the motor has a fairly constant power output, whereas pedaling power comes and goes with each quarter-turn of the cranks, resulting in the suspension compressing with each power-stroke.
The vertically-aligned upper link makes for relatively high anti-rise values near the start of the travel, which means the bike will sit a little deeper into its travel under braking compared to some Horst-link designs with a horizontal rocker ink.
Geometry and SizingThe Megawatt's five size range goes from 435mm reach in small to 515mm in XXL, with nice and consistent 20mm gaps in-between. The stack height on the XXL (which I tested) is taller than most bikes, which makes for an even roomier cockpit than the 515mm reach would suggest because it increases the
spread slightly.
The chainstays are fairly short for an eMTB, at 442mm in all sizes.The effective seat angle is claimed to be 77.5-degrees in the small and medium, rising to 78-degrees in the larger sizes. My XXL test bike measures in at 77.9-degrees at my pedaling height. The head angle is claimed to be 64-degrees, though I measure my test bike at 63.7-degrees. A little deviation from the geometry chart is completely normal when measuring bikes, and all the other measurements are true to what the chart says.
Speaking of measurements, some of Nukeproof's press material says the rear travel is 170mm, but the kinematic charts they provide go up to 165mm. By compressing the suspension fully with a ratchet strap, I measured the vertical travel from full top-out to bottom-out at 165mm, though the usable travel is more like 160mm from where the unloaded shock naturally reaches equilibrium without forcing it to top-out. I've measured the travel on a lot of bikes in this way and it's usual for the real-world travel to under-deliver like this.
Models, Specs and PricesMegawatt Comp - £4,999.99 / €5,999.99 / $5,499.99Megawatt Elite - £5,999.99 / €7,199.99 / $6,599.99Megawatt Factory - £6,999.99 / €8,199.99 / $7,499.99The Factory model I have on test uses a Fox 38 fork with the E-bike damper tune. That's actually slightly lighter compression damping range than the standard fork. The shock uses Fox's light compression tune too, with a medium rebound range. It's cool to see Maxxis' DoubleDown tires from the off, and I was pleasantly surprised by the XT four-pot brakes on this particular test bike, which are pretty much free of the wandering bite point issue Shimano brakes can display.
Ride ImpressionsI'm not going to beat around the bush: Nukeproof have knocked this one out of the park. At 24.6Kg, it's certainly not the lightest, but it doesn't feel like a lump when you're riding. The relatively short chainstays make it appreciably easier to pick up the front to hop or manual over obstacles than many lighter e-bikes with longer stays. But unlike some regular bikes with short chainstays, there's plenty of weight on the front tire to keep it gripping on flat turns without having to lean on the bar. Add to that the very active suspension, which I've setup pretty light on compression and rebound damping, and the bike feels particularly lively and energetic as e-bikes go.
What impresses most is the traction. The bike settles into its early travel very easily, sagging under its own weight, and gets moving at the slightest touch. That makes it feel stuck to the ground and really surefooted on those small bump, low-grip situations. Yet even with 30% sag, there's plenty to push against later in the travel.
The other thing I like is the fit. At 190cm (6'3"), i'm in-between the XL and XXL on Nukeproof's chart, but the XXL suits me very well. There's plenty of room to move around to put weight where it's needed but, as I said, it doesn't require a conscious effort to keep the front tire loaded even on flat or off-camber turns. I could do with the handlebar a touch higher, but that could be fixed with a handlebar swap.
Despite that, I felt really comfortable getting up to speed on rough and steep trails from the first ride. Those first impressions have only grown as I've ridden it more and more. Everywhere from fast bike park terrain to awkward tech, I've felt comfortable and confident on it. It's stable and ground-hugging, but still relatively easy to jump, hop and maneuver around the tighter bits of trail. I've had to run the tires 1-2psi firmer than other e-bikes in my shed with the same tire spec because I've been pushing this one a bit harder.
On steep climbs, the suspension does squat noticeably into its travel, but the steep effective seat angle makes it easy to keep the front wheel from lifting regardless. And while a 29" wheel would be even better when riding up rocky steps, the suspension remains very supple under power which makes it easy to maintain traction on technical climbs.
While all e-bikes climb pretty well, many of them still have awkward handling and suspension characteristics which mean the descents can feel compromised. This is the first eMTB I've ridden which descends practically as well as a regular bike. It's different, of course: there's no hiding the extra weight on a tight rut track or janky rock section, but on the other hand the weight boosts stability and traction on high-speed terrain. Nukeproof have the Megawatt's suspension and geometry worked out so nicely that it capitalizes on that stability without feeling dead or awkward on slower speed terrain. Not bad for a first attempt.
So you are stuck to this type of routing and stuck with an Acros headset, no angle / reach headsets and as you say you have to deal with great big holes in the upper assembly, would it have been so hard to pop a few holes in one of the tubes and stick a rubber grommet in there?
But more importantly - why are they even trying to make a chonky great ebike look sleek and uncluttered?
It's not like there's a lack of downtube to run the cables along.
Threw it out and put a Hope headset it, completely worry free. Changing bearings is a 5min job.
I use Hope headset. It's not only easy to use, but it's the only headset wide enough to take it fully out from a carbon frame without damaging the frame. It has nice wide flange. With cane creek it's super hard.
The trade off between the visual effect (neatness) of a few inches of exposed cables (on a massive , non aero E-Bike) vs the hassles & headaches that come with headset routing (outlined above) is a poor one, for both shops, home mechanics and for longer term durability.
Add in the fact that there doesn’t appear to be a redundant secondary routing system you can use (subtle basic external guides would be perfectly fine) and that would make me (as someone with LBS workshop experience & potentially in the market for an E bike later this year) look elsewhere.
Shame, because it looks great otherwise, but as is so often the case; small details count.
I have the Acros cable routing headset in a Gravel Bike. It probably won't ever see as much dirt thrown around everywhere as my mountainbike in one winter, so I hope it'll hold up long enough.
Any chance of making a 56-66 normal and reach adjust headset to save the day ?
Can I go back to reviewing bikes now @brianpark?
18 months ago I bought my Canyon Spectral:ON with Fox 36 (Rhythm) fork and Fox Float shock for £3000.
I know... I know... pandemic.. supply issues...
(and if anything, the new meta-power 27.5 entry level is 500e cheaper and has the big 630Wh battery)
I’m guessing a few stick that 6000 in the market for 6 months during the 0% period, but it’s likely the minority. Most eBike buyers here are 35+ and buy in cash. I’ve never met someone who financed a bike out of necessity. It’s a bit nutty.
You can always cable tie your stuff externally, but you really shouldn't have to on a 5/6/7k bike
Anyway 24.6 kg for a bike is really too much for me, I'd prefer lighter battery and motor possible with less powerful assistance

"Gigawatt".. you know, as in "1.21 Gigawatts!"
Sorry that I look like I am having way more fun on my eMTB.
Not Sorry that I am having way more fun on my eMTB, then you are having on your MTB.
perhaps leavers just wanted the UK to have the power of self determination regarding immigration, instead of leaving it to Brussels to dictate who/how many they had to let in? call me crazy, but there is nothing racist about setting limits and vetting immigrants.
you see racism everywhere because you go out looking for it.
"careful what you look for. you will likely find it"
And just because immigration has not stopped, does not mean a number of voters weren't hoping so or even convinced that it would by a misleading campaign. The naivety goes deeper: people exist in this country who believed not only new immigration was going to be curbed, but that EU nationals already here would get forced out of the UK and kept asking "why are they still here" days after the vote (i.e. before even actually leaving the EU). Not to even mention some numpties' surprise at non-EU immigration still happening after leaving the EU. So yeah, don't give the average voter too much credit
Saying xenophobia was not motivating a large contingent of voters (note I'm not saying "all voters") and that utilising it was not an integral part of leave campaign's strategy is just trying to create an alternative reality. Those guys knew exactly what strings to pull to tap into that forgotten, economically left behind, previously inactive, disappointed with all politics electorate and get them emotional. Again, blame several consecutive governments for not giving a single damn about those people who struggled with the UK transitioning from a manufacturer and exporter to a financial services based economy.
the reality is that the EU is a failed/failing idea. leaving now before the feces hits the air moving device, is better in the long run. after all, isn't it the position of neo-liberals and Labour that "the ends justify the means?". it cracks me up when Labour wants to stand on principles when it suits them, but then when they lose, its all the coal faced, country bumpkins that are racist!!!!!!
The EU is an organization of corruption, ineptitude and concentration of power. Europe is far too diverse to think that Brussels can possibly know best for all. The smaller the block of humans, the better. the UK should likely be like 9-10 different countries itself. That isn't xenaphobia, it's rationality. I don't fear people that are different or not from a place. I simply want all people to live their best life. I can't possibly know what that is for billions of people, so I want as much autonomy as is possible. countries of 1 human is the ideal, and we work from there. Humans aren't wired to live in the manner the majority of them live now. Being expected to give a shit about anyone outside of your 100-200 people you know, is laughable. You don't care in the same way. you cannot. but the powers that be want to try and shame and pressure you into thinking someone in Nairobi has the same right to resources in YOUR country or town, as you and YOUR family do. that's nuts
I did not say anything about whether the EU works as an institution or not. That was not the topic.
All I did was state the simple fact (no nuance here and I'm not inventing anything) that the UK had full right to limit or stop immigration while being in the EU. The governments, both Labour and Conservative, CHOSE not to exercise that right. I only wrote this to correct your wrong assumption that leaving the EU was necessary to regain that right. The same assumption was mistakenly made by many voters based on campaigners' false claims. What's so complex here that you do not understand?
I have no idea why you are bringing political parties into it, when both major ones had a similar split of leave and remain supporting MPs. You're making things up instead of talking facts and you want to make it a partisan argument, which it most certainly is not.
You're also confused about "Brussels" somehow magically making decisions for all the EU countries. That is not the case and not how the EU works. Again, note I'm not judging one way or another whether it is good or not. Just correcting very simple facts.
Your entire last paragraph is completely irrelevant to this conversation so you kind of wasted your time typing it out but that's fine; for some reason you wanted to voice your opinions on unrelated matters. I guess the fact you try to present opinions as truths is just your style, not uncommon either.
The only thing that's on topic-ish in there is you suggesting I don't know what the word "xenophobia" means. No need to worry. I do and I used it correctly in my post. Please note I used it in a completely different context than you suggest I did, so it isn't really worth me addressing those projections.
I think the bottom line here is that instead of discussing facts with a cool head you got all emotional and created some strange image of me in your mind, attributed certain views and opinions to me that I never shared and you are now trying to argue with that made up image. And you know what, that's perfectly fine. In your head and in your world I can really be whatever you want me to be. I have no influence over that. Who I am in your imagination is entirely up to you. You will have to continue the argument in your head though, that part I can't help you with
Bloody hell I couldn't even afford a battery for even one!
adjective:- very large; huge.
It's all about size
Also many are finding the extra heft makes any bike much more planted and can be quicker as a result. Just have to be a bit stronger to move the bike.
Not entirely switched on with the relationship between customer, manufacturer and the market, are you?
BTW, been running a mullet myself for 1.5yrs, guess I should burn it soon?
In honesty one of the benefits to me is that I am a short arse at 5ft 8 and it really helped there with clearance between the butt and the wheel, I do also enjoy it being a little more 'snappy' and easy to move around but that could be more due to a different frame and setup than anything.
Though I am short I have always loved 29ers and still run one as a hardtail with no intent to go mullet there - but for a 160+mm bike a mullet for me just makes sense.
Maybe you are a fad Mattyboi?
