Spotted: SRAM Prototype E-Bike Motor

Jun 2, 2022 at 2:41
by Seb Stott  

Walking around the pits at the EWS and EWS-E, there was one bike that we caught several fleeting glimpses of, but it was always quickly hidden away. Eventually, I did manage to grab a couple of shots as it stood outside the SRAM pits. It looks like a Nukeproof Megawatt eMTB with a prototype SRAM motor.

The form factor of the Shimano motor on the regular Megawatt is a little different, with a sleeker connection to the downtube.

Why SRAM? Well, it looks very different from the Shimano motor that production Megawatts are built around. We saw it going back and forth between the Nukeproof and SRAM tents in the pits and SRAM staff were seen working on it and riding it. The bike also has a full SRAM build and SRAM-branded cranks.


Aside from the raw finish, it looks similar to the production Megawatt, although the frame is definitely modified to accommodate the different shape and size of motor. I didn't manage to get a photo of it, but there appears to be a top-tube mounted display, too.

Shimano launched their first e-bike motor way back in 2016, and rumors about SRAM entering the fray have been swirling for the last two years. SRAM also has a patent for what appears to be an electronic drivetrain powered by a central battery, similar to what would be found on an e-bike. We'll have to wait and see if that design ends up being implemented, but it would be nice if there was only one battery to charge, instead of charging one for the motor and one for the derailleur.

SRAM has a BlackBox Test Pilot team in the EWS-E this season, so it only makes sense that they'd be using the race as an opportunity to test prototype products. SRAM's official comment was, "No comment."

 It sure would be nice if all eMTB motors have standardized mounts and connectors so one can swap motors as they would anything else on their bike.

 That's probably wishful thinking. Do Ford motors fit into Toyotas without any modifications?

 @endorium: Therein lies another issue with motor and frame pairings. eMTB racing is going to be a thing in the future, regardless of whether anyone here likes it or not. I imagine changing professional race team sponsorships would be a ridiculous pain in the ass for the bike company. Imagine that you're X bike company with Shimano as a partner. You make your frames to fit Shimano motors and race them. Something happens, maybe a falling out, controversy, etc. You're no longer are partnered with Shimano and want to switch to SRAM. Now you're making new frames to accommodate SRAM motors. People here love pushing sustainability, but push back on standardization. There's nothing sustainable about having 17 eBike motors with 17 different mounting configurations and connector types.

 @nickfranko, I'm not saying that I want there to be different motor mount patterns, it's just that I've been around the cycling world long enough to know that it's very rare to have one universally accepted standard for anything.
  • 5 1
 You cant even swap motor or batteries from same brand, without software update?
So really wishful thinking!
  • 13 3
 Then every bike would be stuck with giant first generation motors for years until the next standard was finally accepted, there wouldnt be bikes like the Kenevo SL with tiny motors. There is too much engineering in a motor for it to be standardized without major drawbacks to innovation.

 Shimano sort of do this already. They keep the motor mounts the same with each new drive unit. If your frame comes with an E-7000 you can upgrade to either an E-8000 or EP8.

Begin seeing a trend here? The bike industry is not the auto industry and frame manufacturers (chassis manufacturers) don’t make motors unlike the auto industry. However even in the auto industry there are parts that are 3rd party and surprise they fit across multiple vehicles because they use a standard (DIN as one example).

 I’m assuming that in time (hopefully not soon but probably) motor and battery systems for specific bikes will not be supported and parts will run out. At that point I wonder if somebody will manufacture kits to convert ebikes to bikes, with a bb adapter that bolts into the motor mounts. You could take ~12 lbs off an otherwise useless bike and have something that was pretty fun to ride.

 We are still in the infancy stages of ebike development. Trying force a standard at this point would be pretty silly. These motors will continue to get smaller, more powerful, and far more efficient and will likely have to change considerably from one design to another in order to move the ball forward. Why can't we just be stoked about bikes?

 @REZEN: Thats what I was saying and got downvoted for. Whats the point of a standarized frame mount when you can't buy motors, the same motor from the same brand won't swap because its firmware locked, and many motor manufacturers lock in bike companies to using their batteries? Its like complaining that a Tesla motor isn't easily swappable with another EV.
  • 1 0
 @REZEN: I burned up a motor in my Gen 3 Levo in less than a 3 months. Shifting under the load of an ebike is a drivetrain destroyer. We are far from where we will be with these things. That's not to say they aren't already fun as I'm already on my 2nd ebike, but you can put me firmly on the side of those who believe they have a lot of room to improve.

 @mikekazimer: Gee, looking back at my comments here on pinkbike, I see I first mentioned the Husqvarna Extreme Cross e-bikes with a universal motor mount at the bottom bracket back in, *checks notes* early September 2019.

Heck, you could even put a regular bottom bracket on the bike with an adapter plate once your motor has been forced into obsolescence by the companies that will eventually being forcing you to upgrade by no longer supporting them.

And yes, you can drop almost any Detroit iron into a Land Cruiser with a single adapter plate and no frame mods.

 I put a Ford Small block V-8 crate motor in my 86 Land Cruiser. The stock inline six engine didn’t have power or torque for such a heavy vehicle and when it finally died, it was an easy decision to make. Now it has better acceleration and fuel economy and replacement parts are cheaper and more readily available. I almost went with a Toyota 2UZ-FE V-8 like my 2002 has, but it would have cost twice as much and would have been a more complicated engine swap @Hayek:

 @Superburner: one of the guys at work has been designing a gearbox. At my suggestion, he’s developing it to fit the shimano steps mounting pattern. I don’t know if we will ever have enough spare machine time for it to leave the screen and make it into the real world but it’s the way to go IMO.
  • 1 0
 @ebrown123: about the same time i mentioned both. Every eeb should come with a bb adapter that bolts into the motor mount pattern. Small expense that would save the buyer and the company a lot of headache when the motor goes in for repair or warrantee , or you want to fly with your bike and wouldnt be able to secure a battery, etc etc
  • 2 1
 @won-sean-animal-chin: We agree on that. And since it affects e-bikers it will be called limp mode like it is on cars when the electronics go into shutdown mode. Or maybe it's limp mode as soon as they get on the bike.

Hey @CascadeComponents, we have a product idea for you. Conventional BB adapter plates for the major motor company mounting standards.

 @Xaelber93: well I learned something today! And that's also one of the most Euro things I've ever seen. The ability to shift while stopped couldn't come over to a traditional drivetrain but maybe the ebike spider can accelerate independent of the crank arms? Like you could shift descending without having to pedal. And maybe the shifting takes less getting used to as traditional drivetrains shift under load better so the delay may not be as noticeable.

 That's been a thing for as long as shimano have made the e8000. Di2 can be wired Into the main battery, and when you shift gear it backs off the power automatically. The next model up of my bike (merida e160) came with that exact set up, I was tempted but the reliability/ease of replacement of the mechanical xt won the battle.

In all fairness modularity can makes things easy to switch things around, the military

in its current design since the 80's ? and with LED drop ins, tube ext, Alt battery types, accessories etc
The AR rifle platform is another, with 3rd party bits from Magpul amongst many others,
The desktop PC, build to your own spec.
It can serve longevity, easy repair, save on waste as your not disposing of the complete package

  • 2 1
 My Levo is super low to be sure. The good news is the part that takes the abuse is pretty easy and cheap to replace should you need to. The reason though I believe is to keep the weight as low as possible. These bikes will continue to improve is every way. This is just the beginning. Don't be worried about being an early adopter though. Ebikes are a lot of fun and everyone should add one to their bike collection

 Wouldn’t trust riding a SRAM motor, it sucks bad enough when your brakes fail, or your dropper post stops working. No way would I trust them to build a motor and battery system.

 Not just the brakes. Derailleurs, cassettes, hubs, dropper posts, bottom brackets, chains. You pay a lot for stuff breaking. It's like buying a Ford, GM, or especially a Dodge/Chrysler!

 @CSharp: ???? Are you saying SRAM makes bad cassettes, bottom brackets, and chains? That's lunacy.

Also, current gen GM performance cars are actually head and shoulders above similarly priced German competition. CT5/4 Blackwing, mid-engined Corvette, even the Camaro. So, ya know, kind of sounds like you just repeat things you've heard other people say on the internet....

 @TheRamma: Yup, I said it in my post LOL. You sounded like you want an echo. So, I'm asking you to re-read what I said about SRAM and the almost defunct GM. I know for a fact that the SRAM stuff are crap when my friends keep breaking SRAM shit left and right - hubs, cassettes, chains (I've broken a few that were brand new), jockey guide wheels (like who the f*ck breaks those???), bottom brackets. SRAM probably didn't plan to make bad anything but they just break - so easily in a short period of time!
  • 1 0
 @CSharp: We're talking about manufacturers, take a second. Take a breath.

Some dude (@mm732) claimed they made their chains from "pot metal." When SRAM makes some of the longest lasting chains you can find in X01. Just silly.

You're claiming all this new stuff breaks. If you're breaking brand new chains, cassettes, and bottoms brackets frequently, my suspicion is that it's not SRAM's fault. All those things are pretty reliable at the NX and above level. Breaking jockey wheels sounds like somebody smashed their derailleur, but IDK, I've never done that in decades of biking.

The fact is that SRAM has some pretty cool patents, particularly for cassette construction. They make longer lasting, lighter cassettes than most of the competition. Hence why your shit talking sounds unhinged. Like trashing Shimanos derailleur clutches.

Also, talking shit about GM just shows you have a weird emotional connection to brands. They'll never care about you. They're just trying to grab your money.

 It's a prototype. Not sure why it matters what it looks like at this point?

 @jokermtb: much more reliable, can be fixed by independents if need be and better warranty.

 @jokermtb: I think that's due to the roller bearing clutch. I think Shimano used sprags in their E8000, but switched to something else in the EP8 that resulted in rattle, due to the sprags being heavy and not fully disengaging (adding drag).

The Brose/Spec motor unit still uses a sprag clutch.

 @mtb-scotland: that's true.....most e-mtb motors are not user serviceable (shimano is famous for that), which is kinda sad considering all the engineering and tech that go into making these things.
