Details on noise emissions on the drive unit
The A-rated emission sound pressure level for the
eBike system 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 fea-
ture 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 acti-
vating the <eBike Alarm> service and can be deacti-
vated again via the eBike Flow app.
