Details on noise emissions on the drive unit
The A-rated emission sound pressure level for the
drive unit is < 70 dB(A) in standard operating mode.
If the eBike is moved without authorization, the drive
unit generates an alarm tone as a key feature of the
<eBike Alarm> service. This alarm tone may exceed
the emission sound pressure level of 70 dB(A) and is
80 dB(A) two meters away from the drive unit. The
alarm tone is only available after activating the
<eBike Alarm> service and can be deactivated again
via the eBike Flow app.
