Cycling and shifting with the Rohloff E-14 

The Rohloff E-14 shifter unit combined with the Rohloff SPEEDHUB 500/14 works in unison with a Bosch eBike transmission to provide an optimally coordinated shift between gears. This in turn increases both the rider comfort, safety and battery range while simultaneously drastically reducing the wear of all bicycle transmission components.
 
The direct connection and thus permanent communication between Rohloff E-14 Shifter Unit and Bosch eBike transmission via CAN-Bus, ensures the continuous evaluation of:

- current support level provided by the Bosch eBike transmission
- current crank position
- current power input level of cyclist

A single push of either the ‘+’ or ‘˗’ button on the Rohloff E-14 Shifter will trigger a chain of commands, calculating the ideal time for the Rohloff E-14 system and Bosch eBike transmission to perform the actual gear shift.
- the support level of the Bosch transmission will be reduced 
- the shift command will be sent to the Rohloff E-14 Shifter Unit
- the selected gear will be quickly and precisely engaged at the exact point where cranks are vertical   (least human input   force applied)
- the support level of the Bosch transmission will be re-applied
- this entire process will be completed in approximately 0.2 seconds

A little rider input is also required to ensure the load-free and comfortable shift is completed within 0.2 seconds:
- an optimal cadence of between 50 and 80
- avoid increased pedal force during the shift process
- foresightly cycling, e.g. downshifting before a hill rather than once on it

All the above will ensure the battery range is extended and the number of charges is reduced.
