You can set the roll circumference of your wheel in
millimetres on the VDO M6 or select the applicable tyres
from a tyres table.
The more accurate this setting, the more accurate your speed
indicator and the measurement of the distance you have
travelled. You can find the values for your tyres in the tyre
size table and set these in the device.
ATTENTION:
the values in the table are approximations only.
The actual values can deviate from the values in the table
depending on the manufacturer and the tyre tread.
If your tyre size is not listed in the table, you can accurately
measure the roll circumference.
How to measure the roll circumference:
STEP 1
Stand your bike up and position the wheel to which you
want to attach the sensor so that the valve is directly on
the ground. Ensure that the tyres are fully pumped up in
accordance with the usage instructions. Mark the position
of the valve on the ground with a line or adhesive strip.
STEP 2
Now push your bike forwards in a straight line until the valve
is back on the ground after one rotation.
Again mark the position of the valve on the ground with a line
or adhesive strip.
STEP 3
The distance between the two marks corresponds to your
wheel circumference or wheel size in millimetres.
