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.
Assembly
Checking the speed sensor (see figure A)
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.
When changing a wheel, make sure that the sensor cable is
routed so that it is not under tension and has no kinks.
The CenterLock magnet (4) can only be removed and rein-
serted up to 5 times.
Rim magnet
Note: The rim magnet's alignment with the rim must not be
changed (see figure A).
If a rim magnet is installed, no sensor is required to detect a
wheel turn. The drive unit itself detects when the magnet is
close to it and calculates the speed and any other data re-
quired from the frequency of the emergence of the magnet
field.
Since the drive unit is sensitive to magnetic fields, avoid
other magnetic fields in the vicinity of the drive unit (e.g.
magnetic clipless pedals, magnetic cadence sensors, mag-
netic or magnetised tools, etc.) in order to prevent disrup-
tion to the drive unit.
Operation
A control unit from the system generation the smart system
is required for the starting operation of the eBike. Please ob-
serve the operating instructions of the control unit and, if ne-
cessary, additional components from the system generation
the smart system.
