NuVinci Harmony gear hub
The twist grip on the Nuvinci Harmony actuates
a servo motor electronically on the rear wheel
hub which changes transmission rati o of the hub.
Two operati ng modes are featured on the
NuVinci H8 twist grip and can be alternated
between using the Mode key:
Automati c mode: blue display
The cadence which is to remain constant is
determined with the twist grip. Cadence is
symbolised in blue on the display.
The transmission rati o is adapted automati cally
during travel.
Manual mode: orange display
In this mode, the twist grip determines the
transmission rati o. This is symbolised on the
display in orange.
If the Bosch system ceases assistance due to a fl at batt ery, a minimal
energy reserve remains available to the NuVinci Harmony for shift ing
processes. This can be depleted within approx. 30 min., depending on
the number of shift ing processes.
-> Shift ing is thereaft er no longer possible!
When at a standsti ll, only 50 to 70% of the transmission range is available
on NuVinci hubs. The remaining range is only available while riding.
