- Increased battery range
- Reduced transmission component wear
Cycling and shifting with the Rohloff E-14
The Rohloff E-14 2.0 gear mech, combined with the Rohloff SPEEDHUB 500/14, works in unison with the Bosch Smart System 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 eBike transmission via CAN-Bus, ensures the continuous evaluation of:
- current support level provided by the eBike transmission
- current crank position
- current power input level of cyclist
A single push of either the ‘+’ or ‘˗’ button on the Rohloff E-14 Switch Unit, will trigger a chain of commands, calculating the ideal time for the Rohloff E-14 2.0 gear mech and eBike transmission, to perform the actual gear shift.
- the support level of the 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 transmission will be re-applied
- this entire process will be completed in approximately 0.2 seconds
A small amount of rider input is still required to ensure load-free and comfortable shifts are completed within 0.2 seconds:
- an optimal cadence of between 50 and 80
- avoid increasing pedal load during 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.
