the lower the speed of the push assistance function (at full
power).
The push assistance function must only be used when
u
pushing the eBike. There is a risk of injury if the wheels
of the eBike are not in contact with the ground while using
the push assistance.
To activate the push assistance, briefly press the WALK
button on your on-board computer. After activation, press
the + button within 3 s and keep it pressed. The eBike drive
is switched on.
Note: The push assistance cannot be activated at assistance
level OFF.
The push assistance is switched off as soon as one of the
following occurs:
– You release the + button;
– The wheels of the eBike are locked (e.g. by applying the
brakes or hitting an obstacle);
– The speed exceeds 6 km/h.
The push assistance function is subject to local regulations;
the way it works may therefore differ from the description
above, or the function may even be deactivated completely.
Powering external devices via the USB port
The USB port can be used to operate or charge most devices
that can be powered via USB (e.g. various mobile phones).
Charging requires the on-board computer to be mounted
and a sufficiently charged battery to be inserted in the eBike.
Open the protective cover (8) for the USB port on the on-
board computer. Use a Micro-A – Micro-B USB charging
cable (available from your Bosch eBike dealer) to connect
the USB port on the external device to the USB port (7) on
the on-board computer.
Once the electrical load has been disconnected, the USB
port must be carefully resealed with the protective cover
(8).
USB connections are not waterproof. When cycling in the
rain, do not connect any external devices and make sure
that the USB port is fully sealed by the protective
cover (8).
Important: If electrical loads are connected, this can affect
the range of the eBike.
