The all-new SRAM Eagle Powertrain integrates motor and transmission


SRAM’s all-new and long-awaited motor for electrical mountain bikes merges all of the model’s key applied sciences into one. AXS know-how and the recently-launched Eagle T-Sort Transmission type an integral a part of the brand new SRAM Eagle Powertrain.

In SRAM’s personal phrases its all-new Eagle Powertrain for e-MTBs is impressed innovation, radical simplicity, unmatched integration with Eagle Transmission, clear and easy rider management, and AXS enabled personalisation. The model hasn’t merely developed a brand new motor, battery and controller however introduced all its just lately developed and absolutely developed applied sciences collectively as a totally built-in system.

The perfect electrical mountain bikes are already well-equipped in the case of motor and battery tech. With new developments from Bosch and Shimano is SRAM’s new Powertrain spectacular sufficient to make severe inroads into the full-power e-MTB class? There are solely 4 manufacturers utilizing the SRAM Powertrain initially, with official launches for these new e-bikes imminent, so keep tuned.

We’ve ridden the brand new Eagle Powertrain and have a full trip evaluation of our preliminary ideas and perception on this new know-how and the way it compares to the finest e-bike motors.

Full Energy. Totally in your management

The Eagle Powertrain energy tune applies pure feeling, traction producing, technical transfer finishing, controllable energy to the rear wheel. Developed and confirmed with BlackBox athletes and profiled to work in live performance with how actual riders really pedal. It’s only attainable with SRAM Eagle know-how.

With Eagle Transmission the more durable you pedal, the higher it shifts. Nowhere is that this extra obvious than when paired with Eagle Powertrain.

Using with Eagle Powertrain, Yannick Pontal (SRAM BlackBox Check Pilot Programme) turned the reigning champion within the 2022 EWS-E sequence. His suggestions partnership with SRAM’s engineers and growth staff allowed the model to construct a race-winning system at house on the circuit and in your native trails.

“Our focus is at all times on the rider first. The purpose of the system was to supply the rider with an entire, wi-fi, built-in E-MTB system tuned particularly for efficiency mountain biking. We simplified the trip permitting the rider to give attention to the path.” Michael Hemme, SRAM E-MTB class supervisor

Seamless integration

SRAM’s Powertrain is a chic system that works collectively. The flexibility of AXS pod controllers helps you to assign all powertrain rider instructions – with out the necessity to compromise the bar with the muddle of extra remotes and bar mounted shows. What’s left? The ultra-clean and clever wi-fi cockpit, indicative of any Eagle AXS system.

SRAM  drive unit – Powered by Brose

  • SRAM distinctive software program tune
  • As much as 90Nm of torque
  • 680W peak energy
  • Switchable Auto Shift and Coast Shift
  • Greatest in school derating (warmth vs. energy loss)
  • Pure trip feeling

A lot greater than only a motor, the Eagle Powertrain Drive Unit has been engineered with a reimagined energy supply tune that replicates a much more pure pedaling expertise. It’s a really feel solely made attainable by SRAM’s holistic strategy to the whole system, the place it referred to as upon confirmed motor {hardware} and paired it with Eagle Transmission. It’s an strategy that took learnings from short-comings that plague different motors, comparable to widespread energy losses from super-hard using, and gave SRAM the chance to go additional by using issues comparable to heat-resistant supplies that present superior thermal efficiency and allow longer energy supply.

Battery choices – full measurement and compact

The distinctive Eagle Powertrain battery streamlines the interface between battery and drive unit. Delivering much more energy in a smaller space and tremendous elegant type issue for extra pleasing body silhouettes.

Using a novel C-shaped clip-in or non-obligatory slide-in interface, the Eagle Powertrain Battery helps to help accomplice OE (unique tools) producers of their quest to maintain the burden low and centred. It is available in at a 630Wh compact or 720Wh full measurement and is well detachable with a single Allen key.

630Wh Compact Measurement

  • Low centre of gravity
  • Decrease weight of 3kg
  • Tilt-in mount
  • Empty to full cost: 4.5 hours approx

720Wh Full measurement

  • Most vary
  • Increased weight of 4.1kg
  • Slide-in mount
  • Empty to full cost: 5 hours approx

The AXS App has developed and now’s integral to the arrange and personalisation of the SRAM Powertrain

Customized management by way of the App

A completely built-in AXS ecosystem permits new ranges of personalization for Eagle Powertrain. Structure your cockpit precisely as you want – AXS makes it attainable to assign the Pod buttons. Fantastic tune the texture of Eagle Powertrain Auto Shift options for terrain or the way you’re feeling.

The Eagle Powertrain AXS App makes the off-bike expertise as wealthy because the on-bike expertise.

The Eagle Powertrain AXS Bridge Show is the subtle nerve centre of the whole system, providing you with a management unit that drastically simplifies the expertise. Consider it as an onboard extension of the AXS App, offering every part in a brilliantly illuminated, full shade, waterproof show, protected underneath Gorilla Glass.

  • Energy (quick press): Service Mode / motor help off
  • Energy (lengthy press): On and Off
  • AXS (quick press): Swap between Vary and Rally modes
  • AXS (lengthy press): Open and shut pairing session

“Our Auto Shift algorithm is sort of a bike’s sixth sense, deciding when to shift so riders can keep laser-focused on their trip. It’s not simply good tech, it’s the last word using companion.” – SRAM

Auto Shift

What may really feel extra pure than not having to consider shifting when you trip? Eagle Powertrain Auto Shift is a feat that senses and interprets rider enter to ship an extremely intuitive expertise. Planning an assault or just need to override the system? Auto Shift seamlessly accepts rider instructions, to be prepared to your subsequent transfer.

Shift whereas coasting

Eagle Powertrain Coast Shift permits the chainring to maneuver freely from the cranks, letting you shift whereas coasting. Why? Opening the probabilities of shift wherever efficiency (whether or not pedaling or not) places you in complete management, even when the terrain forward isn’t.

Vary and Rally modes

Lowering complexity with two help modes that may be simply adjusted and customised for particular person want. The place others provide you with pointless energy modes and complicated names, Eagle Powertrain makes use of simply two.

Vary Mode

With the contact of a Pod button, toggle to Vary Mode for longer routes, simpler terrain or when conserving energy is an efficient transfer.

Rally Mode

Toggle to Rally Mode for shorter rides or everytime you need entry to the capabilities of energy. Preserve it easy.

Eagle Powertrain is an entire system particular to the bike producer. Further or alternative SRAM batteries, vary extenders, chargers, and equipment can be found within the aftermarket.
