Harmony? / Harmony? H|Sync? | Fallbrook Technologies Inc.

Bosch has fully integrated the Rohloff 500/14 into it's CAN-Bus, as well as the Nivinci Harmony H|Sync.
So a shifting command (wheater it's automatic initialised or manually started) first reduces the motor power before starting the shifting process.
Same with Shimano Nexus Di2 and Shimano Alfine Di2 automatic gear hubs on Bosch bicycles.
