"Eagle Powertrain" is Sram's (belated) answer to the competition from Bosch and Shimano. The recipe is a mid-motor developed in cooperation with Brose and optimized for e-mountainbike use, delivering a peak output of 680W and a contemporary torque of 90Nm. The motor weighs around 2.9kg.

The drive is integrated into Sram's AXS system and offers wireless pod controllers to the left and right of the handlebars and full AXS communication via the AXS bridge display embedded in the top tube. An app is used to elicit additional setting options and functions from the system. However, the app is not necessary for riding; as soon as all AXS components are connected, the e-mountainbike with Sram motor is ready to ride.

Few surprises

A 630 Wh battery (weight 3.1 kg) is available for open down tube frame constructions and a 720 Wh battery (weight 4.1 kg) for slide-in and closed down tube frame constructions. A range extender with 250 Wh is also in the range.

With "Range" and "Rallye", two support modes are available, each mode can be controlled via the app. An automatic shifting system is also on board, which ensures that the cadence remains constant without having to shift gears on the pod. The system offers seven different levels to adjust the automatic system. With Coast Shift, the front chainring can rotate independently of the cranks, allowing you to shift gears without pedaling.

Speaking of pods: The previous AXS controllers with the original rocker or the Rocker rocker cannot be used with Powertrain. Eagle Powertrain is only compatible with the Pod Controller due to various e-bike-specific functions. And remote controls for dropper posts that are not from the Sram AXS line could get in the way of the iPods.

These manufacturers are at the start

To get started with the E-drive, the system should be combined with a SRAM XX, X0 or GX Eagle transmission. Powertrain can also be used with mechanical or Eagle AXS drivetrains, but then you lose the Auto Shift and Coast Shift function. Sram is launching the new e-drive with Propain, Nukeproof, Transition and Gasgas.
