Automatic compensation deactivated during standstill (default)
The kilometre compensation occurs during bicycle standstill only when the tuning is
deactivated using a mode without tuning support (this is ECO and TOUR as standard).
Turbo -> Walk -> Sport -> Walk -> ECO -> Walk
Increasing the wheel circumference
The function increases the wheel circumference in increments of 2 cm up to a maximum of
20 cm. This enables manual fine calibration of the speed indicator and the kilometre
measurement. After entering the code, the correction value is displayed briefly as speed.
2.0 means + 2 cm wheel circumference.
ECO -> Walk -> Tour -> Walk -> Turbo -> Walk
Reducing the wheel circumference
Turbo -> Walk -> Tour -> Walk -> Eco -> Walk
The function reduces the wheel circumference in increments of -2 cm up to a maximum of
-20 cm. This enables manual fine calibration of the speed indicator and the kilometre
measurement. After entering the code, the correction value is displayed briefly as speed.
2.1 means - 2 cm wheel circumference.
OFF mode deactivates tuning (Default)
OFF -> Walk -> Tour -> Walk -> Sport -> Walk
Selecting the OFF mode deactivates the tuning functionality. After switching on the ebike
the functionality will be in accordance to the setting of the general tuning parameter. As
default the tuning will be activated again. The stored values for the comparation
functionality will be erased.
OFF mode without functionality
Sport -> Walk -> Tour -> Walk -> OFF -> Walk
In this mode the OFF mode doesn’t effect the tuning mode. We recommend this mode if
the tuning is also activated on the TOUR and ECO mode because otherwise no mode
without tuning is available for the comparation functionality.
