Information on the noise emissions of the drive
unit
Typically, the A-weighted noise emission level of the drive
unit is < 70 dB(A). A key feature of the <eBike Alarm> ser-
vice is that the drive unit will emit an alarm tone in response
to unauthorised movement of the eBike. This alarm tone can
exceed a noise emission level of 70 dB(A) and measures
80 dB(A) at a 2 m distance from the drive unit. The alarm
tone is only available once the <eBike Alarm> service has
been activated and can be deactivated via the app eBike
Flow.

Speedsensor (slim)
The speed sensor (2) and its CenterLock magnet (4) or
spoke magnet (3) are mounted ex works in such a manner
that the magnet, after a turn of the wheel, moves past the
speed sensor with a clearance of at least 2 mm, yet no more
than 15 mm.
If any structural changes are made, the correct distance
between the magnet and the sensor must be complied with
(see figure A).
Note: Make sure you do not damage the sensor or the sensor
holder when fitting or removing the rear wheel.
