19 USING THE BOTTOM BRACKET
The BOTTOM BRACKET is already fitted to your e-bike on delivery. You are not
permitted to make any changes to the BOTTOM BRACKET as you may affect the
safety and function of the drive system.
It may be necessary to align only the speed sensor
[B.2]
connected to the BOTTOM
BRACKET, as well as the corresponding spoke magnet
[B.4]
in some circumstances.
19.1 Correct position/alignment
For the drive system to function correctly, the speed sensor
[B.2]
and the spoke
magnet
[B.4]
must be correctly positioned and aligned on the rear wheel.
• The spoke magnet must be positioned on the spoke so that it can move past
the speed sensor freely at the height of the marking.
• If the spoke magnet and speed sensor are too close together and there is a risk
of them coming into contact, the two parts could be damaged and may need
to be replaced.
• The distance between the mark on the speed sensor and the spoke magnet
must be in the range between 4–15 mm.
* The chain line depends on which Spider variant is installed.
