Microshift’s prototype 11-speed electric eXCD drivetrain was on display at the Taipei 2016 Cycle Show.
Said to be available sometime in 2017, it looks promising.
More than three years later and still waiting for delivery.
Meanwhile . . .
There is a competing product from Archer Components available now that seems to deliver on the Xshifter promises:
The D1x Trail Shifter transforms nearly any mechanical 1x drivetrain into a high performance electronic shifting machine.
This is retrofit electronic shifting.
The bike you rode today could be digitally tuned and shifting smooth tomorrow.
