The SRAM Eagle Powertrain e-bike motor has launched
SRAM promises to make trail riding easier with the new SRAM Eagle Powertrain e-bike motor and drivetrain system, which features integrated components, automated shifting, and only two support modes. There will be two batteries available — a compact 630Wh unit intended to be used with “open” down tubes, and a larger, 720Wh battery that fits inside the frame and is intended for “closed” down tubes.
It is stated that both batteries on the SRAM Eagle Powertrain e-bike motor may be charged on or off the bike and are simple to remove with a single Allen key. On the other hand, some Eagle Powertrain bike models have batteries that are fixed in place.
There is also a 250Wh range extender that fits to the bottle bosses of the bike. When the extender is mounted and the bike is in Rally mode, the motor uses up the main battery while the extender is in Range mode. Auto Shift is another feature built into the software. It enables the drivetrain to automatically change gears even in varied power settings and to choose the appropriate gear for the rider’s current pedaling cadence.
Additionally, SRAM introduced Coast Shift, a feature that permits gear shifting by the drivetrain even in the absence of pedaling. This is an accomplishment that is typically unattainable with a chain drive system since switching between cogs requires the chain to be moving. However, while the rider is not pedaling, the Coast Shift feature allows the engine to intelligently engage itself and turn the chain. It may seem easy, but using a chain drive to change gears is revolutionary.
In short, the rider just needs to provide a brief burst of power without the need to pedal to start the chain moving and enable the derailleur to function. The drivetrain takes care of the Auto Shift and Coast Shift functions, so the rider doesn’t have to worry about them and can concentrate all of their energy on the road ahead.
The new SRAM Eagle Powertrain e-bike motor and drivetrain system will probably only be available on high-end e-bikes, although it should be available on SRAM-powered models from a number of manufacturers.
