Today SRAM unveiled their new Eagle Powertrain E-MTB system. Merging SRAM’s key technologies into a single system, Powertrain is designed to offer riders a complete, wireless, integrated E-MTB system and unmatched control. Check out an overview of the press release and the system highlights below.

Press release

Eagle Powertrain is inspired innovation, radical simplicity, unmatched integration with Eagle Transmission, clean and simple rider control, and AXS enabled personalisation.

System Overview

  • AXS Bridge Display
  • Pod Controllers
  • Eagle Transmission
  • SRAM Drive Unit
  • Speed Magnet and Ring
  • Battery
  • RangeExtender (optional)
  • AXS App
  • Head Unit
  • Rockshox Reverb AXS

Go for unbelievable ease.

The Eagle Powertrain power tune applies natural feeling, traction generating, technical move completing, controllable power to the rear wheel. Developed and proven with BlackBox athletes and profiled to work in concert with how real riders, like you, actually pedal. With Eagle Transmission the harder you pedal, the better it shifts. Nowhere is this more apparent than when paired with Eagle Powertrain.

Go for seamless integration.

The versatility of AXS pod controllers lets you assign all powertrain rider commands – without the need to compromise the bar with the clutter of additional remotes and bar mounted displays. What’s left? The ultra-clean and intelligent wireless cockpit, indicative of any Eagle AXS system.

The unique Eagle Powertrain battery streamlines the interface between battery and drive unit. Delivering even more power in a smaller area and super elegant form factor for more pleasing frame silhouettes.

Go for personalized control.

A fully integrated AXS ecosystem allows new levels of personalization for Eagle Powertrain. Layout your cockpit exactly as you desire – AXS makes it possible to assign Pod buttons. Fine tune the feel of Eagle Powertrain Auto Shift features for terrain or how you’re feeling using the Eagle Powertrain AXS App.

Go for the win.

Eagle Powertrain has already won the toughest race series out there: The UCI EWS-E. Cloaked by the Blackbox wing, but exactly like the Eagle Powertrain system available today.

Riding with Eagle Powertrain, Yannick Pontal (BlackBox Test Pilot Program) became the reigning champion in the 2022 EWS-E series. His feedback partnership with our engineers and development team allowed SRAM to build a race-winning system at home on the circuit and on your local trails.

Our focus is always on the rider first. The goal of the system was to provide the rider with a complete, wireless, integrated E-MTB system tuned specifically for performance mountain biking. We simplified the ride allowing the rider to focus on the trail.

Michael Hemme, E-MTB Category Manager

CONTROLS

AXS Bridge Display

The Eagle Powertrain AXS Bridge Display is the sophisticated nerve center of the entire system, giving you a control unit  that greatly simplifies the experience.

Think of it as an onboard extension of the AXS App, providing everything in a brilliantly illuminated, full color, waterproof display, protected under Gorilla Glass.

Pods: Familiar Contact Points

Toggle between Range and Rally modes. Control your Rockshox Reverb AXS dropper post. Press and hold to multi shift Eagle Transmission. AXS control, encompasses everything.

Our Auto Shift algorithm is like a bike’s sixth sense, deciding when to shift so riders can stay laser-focused on their ride. It’s not just smart tech, it’s the ultimate riding companion.

Dominique Fuss and Victor Freyssinet Electrical and Software Engineers

Auto Shift. When you want.

What could feel more natural than not having to think about shifting while you ride? Eagle Powertrain Auto Shift is a feat that senses and translates rider input to deliver an incredibly intuitive experience. Planning an attack or simply want to override the system? Auto Shift seamlessly accepts rider commands, to be ready for your next move.

Shift while coasting.

Eagle Powertrain Coast Shift allows the chainring to move freely from the cranks, letting you shift while coasting. Why? Opening the possibilities of shift anywhere performance (whether pedaling or not) puts you in total control, even when the terrain ahead isn’t.

Two ways to get the most: Range and Rally

Reducing complexity with two support modes that can be easily adjusted and customized for individual desire. Where others give you unnecessary power modes and confusing names, Eagle Powertrain uses just two.

Range Mode

With the touch of a Pod button, toggle to Range Mode for longer routes, easier terrain or when conserving power is a good move.

Rally Mode

Toggle to Rally Mode for shorter rides or whenever you want access to the capabilities of power. Keep it simple.

It was an incredible opportunity to develop a fully holistic system. All components–from the display to the derailleur–forming one perfectly synced unit. Our wireless AXS technology enabled us to create features like Auto Shift, Coast Shift and the limitless options of Eagle Transmission provide shifting under full load.

Sebastian Dueweling, Chief System Engineer

Everything in control with the AXS App

The Eagle Powertrain AXS App makes the off-bike experience as rich as the on bike experience. From customizing drive unit power output to simply checking battery life while off the bike, the AXS App lets you view and fine-tune a host of features, right from your phone.

COMPACT AND FULL SIZE BATTERY

Powering the Eagle Powertrain. Utilizing a unique C-shaped clip-in or optional slide-in interface, the Eagle Powertrain Battery helps to support partner OE manufacturers in their quest to keep the weight low and centered. It comes in at a 630Wh compact or 720Wh full size and is easily removable with a single allen key.

SRAM Drive Unit: Powered by BROSE

So much more than merely a motor, the Eagle Powertrain Drive Unit has been engineered with a reimagined power delivery tune that replicates a far more natural pedaling experience. It’s a feel only made possible by our holistic approach to the entire system, where we called upon proven motor hardware and paired it with Eagle Transmission. It’s an approach that took learnings from short-comings that plague other motors, such as common power losses from super-hard riding, and gave us the opportunity to go further by utilizing things such as heat-resistant materials that provide superior thermal performance and enable longer power delivery.

  • SRAM unique software tune
  • Up to 90Nm of torque
  • 680W peak power
  • Best in class derating (heat vs. power loss)
  • Natural ride feeling
  • Quiet

Availability

At launch, SRAM Eagle Powertrain will be available on bikes from following brands:

  • PROPAIN
  • NUKEPROOF
  • TRANSITION
  • GASGAS Bicycles

As more brands release models specced with Powertrain we should begin to see it trickle into the South African market, but don’t expect to see it on bike shop floors just yet.

I knew when I saw Trek launch the Exe alloy with transmission there was a little wire in the photo running to the derailer , that meant there was so much more to Transmission than we initially saw and I didn't expect this but well bloody done. Impressed they got Brose onboard ...

If I remember correctly in the last couple of months Sram did have a system for the e bike, where the AXS derailleur(not transmission) was powered by the E bikes main battery with a small wire running to the back, almost like a shift cable.

I don't care for any of this…sram or shimano….And it doesn't matter because i’m not the target market. Someone out there will love it.
 

I watched a youtube vid the other day of a drool worthy, boutique brand mountain bike and one of the first comments on the video were:

”why would anyone still buy a normal bicycle, total waste of time and money”

There are people/kids/fat guys out there who feel this strongly about e-bikes, and they are allowed to, they are wasting their own time and money imo😜

I definitely won't be purchasing a 250k bike in my life ever 

 

but working all week with no time to ride and limited time to train and then get killed when i want to ride 30km of enduro on the weekend has me in two minds

There's definitely a place in my future for an e-bike. But I'm sure I won't work nearly as hard on an e-bike, so for now my *** does just fine.
