The operating unit is used to make all settings and issue commands to the drive system. It can be fitted on either the right or left of the handlebars and easily changed over so the display is on the correct side.
An intuitive display unit and convenient display functions for the operating status provide extensive information about operation, e.g. speed or range. An integrated Bluetooth 4.0 module makes it smartphone-compatible. A micro USB interface is used to connect to the service tool and also provides a charging function for smartphones.
