Assembly
Inserting and removing the battery
For inserting and removing the eBike battery in/from the
eBike, please read and observe the battery operating in-
structions.
Checking the speed sensor (see figure A)
The speed sensor (2) and its spoke magnet (3) must be fit-
ted such that the spoke magnet moves past the speed
sensor at a distance of at least 5 mm and at most 17 mm
with each rotation of the wheel.
Note: If the distance between the speed sensor (2) and the
spoke magnet (3) is too small or too large, or if the speed
sensor (2) is not properly connected, the speedometer dis-
play will fail and the eBike drive unit will operate in emer-
gency mode.
Should this occur, loosen the screw of the spoke magnet (3)
and fasten the spoke magnet to the spoke such that it runs
past the marking on the speed sensor at the correct clear-
ance. If the speed is still not being indicated on the speedo-
meter display after doing this, please contact an authorised
bicycle dealer.
