I'm one for sizing down, but did they give you a size small there Steve?😂
What a nice time to be a rider.
First, all my gear is by SRAM except their brakes. But I do surely think that Pinion will have the complete system to beat! Enclosed Gears that always stay clean.....Less weight on the back wheel with everything in the Motor casing. Sure seems like the future to me....I love my current wireless setup but Pinion with enclosed gears & Motor seems to be the way to go.
for shure. this is how motorcycles have been doing it for ages.
so why not sram brakes ?
@@awfully.average I like how Hope Brakes install, on-the-fly adjust and perform better than any I’ve tried…
I totally agree about gearboxes being the future for emtbs and ebikes in gerneral. Derailleur systems with there lower friction make sense for cycles that rely on human power, but not for those that power assisted for the points you raise above, and many more.
But will it be like motors, unserviceable and water ingress risk with bearing?
beautiful looking Nukeproof. cant wait for the bike review.
Nobody needs an automatic transmission on a mountain bike... what we need is a motor-gearbox unit and Pinion has made it. This Sram "powertrain" is already born old.
Yes and VERY limited availability here in USA. :(
I love that Bike! It looks pretty mean! It can handle anything 😮
First 10 grand megawatt
Just hope the motor is long lasting and reliable. Looking really good
nice bike
Kryptotal - good choice!
Seems like a complicated way to create a gearbox type experience without a gearbox.
I just ride with my Stumpjumper Expert and be happy. No motor, Battery autoshift, wireless and autoshift.
If you think about it, 90% would be happy with a NX-Groupset and 98% with GX/SLX or just a normal light Hardtail with fast rolling tires 😉
And?
I don’t want all that auto shift & wireless stuff. Just more stuff to go wrong in my opinion. Plus I enjoy using well setup cable shift gears. Not that I’m against new kit as I ride a Mondraker e-bike equipped with Gen4 Bosch, but I enjoy manually choosing the gears, timing my pedal stroke to change gear smoothly etc…
I love automatic transmission in my car though 😂
Here’s a crazy idea…don’t buy it.
@@tomhuber5372 oh wow, hadn’t thought of that!
belt drive Brose?
Oh yes knew sram would have something up there sleeves.. 😮
Another 11 minute advert. Fascinating.
Is frame attachment pattern identical to any other motor?
2:52 6 UFOs watching Steve
Nice looking bike. How is the motor noise? Any rattles when descending like the other motor (I cant recall if it was ep8 or Bosch). Hopefully we can see one soon in the US and get test rides in.
So automatic shifting on uphill at full power, I'm curious how long the chain will last.
I want to retrofit that into my Santa Cruz Bullit
Maybe we’ll get a bike soon, that’ll go for a ride without us so we don’t need to put any effort in all. 🎉
11:00, does this mean you can change the cadence at which autoshift operates?
Yes you can
Ah i love new technology, especially on groundbraking bikes😊
where else would you brake?
Now that's funny.@@IIISentorIII
Why do people actively like pointless comments?
I see a wire going to that deraileur. Does that mean it's powered by the bikes battery?
So I wonder if specialized is going to go with sham to get auto shift or stick with Bros. Or if you could add auto shift your specialized levo
Sram use brose motor here. So yes you will see this technology on new specialiezed 👍
can it work with the EP801 motor for
auto shift and coast shift?
Is there an availability date for them ? 2024? And what about a price range?
What location was this filmed in? looks amazing! And I do want autoshift!! 🙂 Not sure why anyone would not like it, but it is not a must, it is a thing you can buy if you want.. And I will!
Industry is missing a trick with ebike transmission. Longevity and robustness should be the priority. Plus do we need 52T cassettes on ebikes?
Could get away with even a 9 or 10 speed cassette
@@islandaerial3414 you've got some big jumps on a 9 or 10 speed cassette if you want a 500% range - negated by the motor assistance to a degree, but it still makes the changes more clunky and you'd notice the cadence change more too.
I agree a 10 speed transmission is likely to be a bit more robust/last longer than a 12 speed designed for non-assisted bikes, but a lot of that can be negated by changing gears sympathetically and not mashing the pedals everywhere...
Ultimately though - as other people have suggested - dragging a chain across a concentric set of cogs is a pretty rudimentary way of changing gears on a bicycle - a 10 speed gearbox style transmission is likely to become the standard for eMTBs over the next few years I suspect.
@@jmo2752i ride 10 speed deore on mine. havent found a hill i couldnt climb.
Give them a bit more time and they may come up with something as good as pinion’s gearbox
From Sram? I really doubt it.
only of they find a way to make more money out of it which I seriously doubt it.
That's a nice bike Steve... I look forward to hearing more about it
Should I go with this Nukeproof or the Canyon Strive:ON LTD?
love watching high technology to see where biking is heading , but. i cannot afford it .
Most up to there eyes in credit cards and loans to buy this stuff...that is not needed at all
So auto shift and coast shift, not too dissimilar to Shimano auto shift and coast shift, but like both, unless you run the complete system you don't get the benefit of the shifting options, and then there's the Brose motor, there's still the conundrum of do you purchase your preferred ststem or, do you buy.your preferred bike brand, personally for me it's bike brand first.
All the tech is great, but my concern is the reliability of the Brose motor!
I'm waiting until it steers for me. Then I'm in.
Only one question... when can I retrofit my Levo with this?
Probably not retrofit (unless they design a different TCU), but I can see this being adopted by Specialized on some of their higher end models in the future - they already spec the T-type AXS transmission on a number of 2024 model year bikes.
@@jmo2752 I wouldn’t be entirely surprised if this is the same motor that is used in the Levo, but a new TCU. Also, it appears that SRAM has run a wire from the main battery to the RD so that both are charged/running on one common battery, which I think makes a lot of sense for eBike application, and is likely why SRAM is introducing these new batteries.
Given how closely Specialized, Brose and SRAM are, I’d be surprised if this wasn’t on their new bikes in the coming model year. I also wouldn’t be surprised if this is somewhat of a handoff of the relationship from Specialized/Brose to SRAM/Brose as I know specialized has eaten a whole lot of warranty repairs outside the warranty period, and using a “SRAM Powertrain” offloads all that liability to SRAM if Brose wasn’t already forced to eat the expenses of warranty repairs as a part of their agreement with Specialized.
Would so much rather a 29/29.
To complicated to fix it you will have to go back to shop plug in ? Still belt drive and wots it going to be like after a wet muddy winter in Great Britain ?
what's vs wots
How tall are you and what size is tht nukeproof ?
about damn time, but the only thing I don't like is the assumption that we only need SRAM's 2 calibration profiles, one of the nice things about brose, and specialized, is the ability to moderately tweak the calibration "tune" of the power unit to suit the riders needs.
One other concern I have is just the dominance that SRAM has over the industry, which in one part is good because you can have everything interoperate with each other, but like all monopoly's (unless they have good opensource community support) it makes the consumer not able to have options for 3rd party products if they chose to.
One last comment; the AXS controllers aren't horrible but, would like to see a more robust and clean handlebar controller that doesn't look like a ball sac hanging off my bars, like you see on the receiver hitch on trucks. Once again its about options, so if brose/sram offer options to use 3rd party designs for controllers, then everyone will benefit.
All the tech is great, but my concern is the reliability of the Brose motor!
How much?
The motor looks big or is that just the frame design?
It's a Brose motor, so it's big and ugly.
It does look big
The old, belt driven and constantly belt-troubled Brose drive S Mag... That's what we waited for?
There goes my other kidney
Very nice but honestly waiting for the pinion mgu
Amazing, how much does this 3500 dollar bike cost?
Can this new Sram motor be used with mechanical derailleur and dropper? I don't care for the auto-shifts.
Is this a review or a sponsored material ?
I want one but just got laid off today by the police 😞
They didnt even give usb port for charging
Its the moped of mountain bikes 😂😂 if you can't change gear its the moped for you 🚴♂️🐴
Can’t ride a moped at a bike park
You could buy a really expensive three piece suite or a ride on mower or any other similar irrelevant item that has nothing to do with mtb
@@frankmatibs8076 thanks for that information i was going to take my motocross bike if you hadn't told me lol 😂
It's a very nice machine, looks amazing in white too and some excellent tech to boot.... but I won't be ordering one. I'll be going to a brand that offers me a Full 29er option. So fed up with the manufactuers forcing the mixed wheel size on us. Sad, because I love my current Nukeproof Mega and it's a great bike, but I'm not parting the better part £7k unless I can have both wheels the same size, than you very much.
Are we talking about bicycles anymore....
SRAM add some patents showing the battery above and around the engine, avg around 400/500W.
A bit disapoiting to see it's a copy of all other engines.
And 2 modes? Really?
Nice, but I'd rather have the pinion...
Tom....I really think that is the future for sure!!! Motor Gearbox unit!!! Yea Baby!
Wow Steve these are becoming more and more pure advertisements. Amazed how much different Mike Kaizmier from pinkbike feels about autostart. His views made a lot more sense to me. I am becoming very dissallusioned with this show
Agreed. This is no just advertising.
Like one dude said, this is like polishing a turd. Pinion is the way to go.
Well I have to say that in my case, the rider was always the weakness.
it starts wearing off the cassette after 2 weeks, i regret purchasing this system, now i have to change 600 $ cassete instead of 100-200 $
So much better than the Shimano stuff !! Absolute next level
A little disappointed you didn’t honestly review how it rides. Another reviewer found that the system isn’t always in the right gear, especially up a steeper grade. Hopefully when you review the bike, you’ll give an honest review of the system.
Not really going to need that auto shift on those trails professionals smoking down red trails not sure ! a great bike not whinging that's the price of an entry level fiesta hatchback would imagine 🤔
I have acquired some Autoshift bikes from the 70's and 80's and the are amongst the most annoying junk that I own. Also tried an auto 3 speed shimano system 10 years ago and it was still just as annoying to ride.
Automatic cars were crap in the 1970s & 80's too... things have moved on.
@@jmo2752the dereilleur system is still the same at its core. with autoshift you will be always grinding the gears. with an igh or internal gearing its better
@jmo2752 but cars don't have a transmission conceived 100 years ago... you may add all the electronics gizmos but still remains a cassette-derailleur transmission with all its flaws.
@@jmo2752 the issue I hated the most was the unexpected change in gears under load, which can be just as annoying as a skipping chain in a poorly adjusted derailleur
I'm not disagreeing with you@@chrisqwerty - certainly auto-shift using a derailleur system still seems like a recipe for disaster! - only that I imagine it is now a lot better/smoother than something from 30-40 years ago...
Does anyone think this is going too far. ... Next there will be cruise control and riderless bikes.
I love my ebike but part of riding MTB is the interaction with the bike and changing gears is part of that.
One of the things that makes SRAM's new system unique compared to other systems is that it integrates with SRAM's system...how did you say that with a straight face?! 😆
Tell us about the bike dammit!
This doesn't really sound groundbreaking to me. Auto-/coast shift seems similar to Auto/- free shift from shimano. The lever design might be good but isn't new by any means and for the assist they market having less as an innovation.
The drivetrain has also been already introduced. I get it, scram catched up, but there isn't much innovation most of it being software.
Uhmm keep it simple! 😅
The only thing holding me back is the S Mag motor, I'm not convinced the belt is fit for purpose @ 90nm. That said, if you consider the Brose motor roadmap i.e. their development of the Brose Drive 3 system (releases 2024) which ditches the belt and provides 410% assistance plus 814w battery. That's the game changer for me. So I'm holding back until SRAM adopts the new Brose Drive3 system as their new powertrain.
Great point! All the tech is great, but my concern is the reliability of belt in the Brose motor!
SRAM has rendered Shimano irrelevant once again. Why would anyone buy anything Shimano these days? SRAM has better groupsets, better app integration, the best mtb and gravel groupsets, the best powermeters, crankarms that don't delaminate and are not dangerous...
Ah well, out with a stocking and a gun. I think I’ll need to rob a bank to afford this.
I remember waaaay back when….you could enjoy a bike ride without any tech or electronics…just sayin…
Thanks for your useless comment.
It's getting out of hands. Pun intended.
its a brose 2.2+ with all the unreliability associated with it. auto shift takes away freedom. it will be prohibitively expensive and only the well heeled pretty boys will be buying. a case of 'just because we can". gearbox motor combo is where real progress will happen
you can turn autoshift off and regain your 'freedom'
Meh, we want smaller powerful motors. Auto shift is a "nice to have".
That looks like a 50lbs bike 😂
Outdated already by pinion, give us what we want sram
the problem is a pinion style integration means less money. Sram bothered to do all of this to get more money. It would not make any sense for them to go into a direction that brings them less money. They are in this business to make money.. big money, not to make best components for mtb-ing or mtb-ers.
@@eugenux yep they will wait for till they have no choice or buy piñon and kill it off.
pointless, Pignon gearbox should be placed in all EMTB.
Shimano was first. With auto shift and coast shift. Sram is just plagiating.
looks big, bulky and ugly. looks like the cheap chinese copy of the unit you can find on Specialized bikes. It makes Bosch, Fazua and TQ look like premium stuff... like Mercedes, Audi and BMW compared with cheap chinese Renault copies. Better to avoid it...especially if it has the same belt problems as the unit on Levos.
edit. it also made the megawatt look so much uglier than before
does the main battery power the shifter and shift pods too?
