Display

The VDO M1 WR has a large, easy-to-read display that can be
divided into three areas.

– The top line of the display shows the value
for the selected function.
– The middle line displays “am” or “pm” if the 12-hour
clock format is used. It also displays whether kmh or mph
has been selected for the speed indicator.
– The bottom line of the display shows the name
of the selected function in clear text.

Only ONE function at a time appears on the display.
To return to the speed indicator from a selected function,
e.g. ride time, press the SET button.

Functions

The VDO M1 WR has the following functions

Current speed

With a wheel circumference of 2,155 mm,
the maximum possible speed is 199 kmh or 124 mph.

Current distance

The current distance counts up to 999.99 km or miles.
If this maximum value is exceeded, the counter restarts the
current distance calculation at zero.

M1 WR

Current ride time

The current ride time counts up to 99:59:59 HH:MM:SS.
If this value is exceeded, the ride time counter restarts at
zero.

Current time

(in 24-h or 12-h format)

Total distance

(Cumulative value for all trips)
The total distance counts up to 99,999 km or miles.
If this value is exceeded, the total distance counter restarts at
zero.

24-H format 12-H format

If the unit is switched from miles to km and the conversion
result is greater than 100,000 km, the counter is reset to
zero.

Operation while cycling

While cycling, the display functions can be accessed by
pressing the BIKE button.
Pressing the BIKE button shows the next function on the
display.

Only ONE function at a time is shown on the display.

To once again display the speed, the SET button must be

Sleep mode

If you take a break and the M1 is in the bracket,
the computer switches to sleep mode after five minutes.

If you set off again after a break, the VDO M1 has an
auto-start function.

The VDO M1 instantly switches back to the function mode and
the current speed are once again displayed.

Attaching the bracket and the sensor

M1 WR

Start by attaching the sensor and the magnet.

STEP 1

Place the rubber shim under the sensor. Attach the sensor to
the fork side that corresponds to the side on which you later
want to attach the computer to the handlebars (right or left)
using the cable ties supplied (loosely at first, do not pull tight
just yet).

ATTENTION: the sensor mark on the sensor should point to

the spokes. Depending on the space available, the sensor can
be fitted to the front, inside or back of the fork.

STEP 2

Attach the spoke magnet to an outside spoke. The rod-shaped
magnet core points toward the sensor with the VDO logo.
Align the magnet with the sensor marking on the sensor
at a distance of approx. 1- 5 mm.

STEP 3

Align the sensor and the magnet in their final positions and
fasten them in place: pull the cable ties tight and push the
magnet in firmly.

STEP 4

Move the cable along the fork until it reaches the fork bridge.
From there, wind the cable further along the brake line until it
reaches the handlebars.

STEP 5

Decide whether you want to use handlebar or stem attach­ment and rotate the base of the handlebar bracket by 90°
accordingly. To do so, undo the screws on the bracket,
remove the foot and rotate it 90° then insert and tighten
the screws again.

ATTENTION: do not overtighten the screws.

STEP 6

Guide the cable ties through the slot in the handlebar bracket,
place around the handlebars or the stem and pull (do not pull
tight just yet).

STEP 7

For handlebar attachment: align the computer angle
to achieve optimum readability.
Now pull the cable ties tight.
Use clippers to snip off protruding cable ends.

A helpful attachment video can be found on our website.

How to insert the computer:

STEP 1

Place the computer into the bracket in a 10 o’clock position.

STEP 2

Rotate the computer to the right into the 12 o’clock position
and click it into the bracket system. A noticeable resistance
must be overcome to move it into place.

STEP 3

To remove the computer, rotate it to the left (without pushing
or pulling).

Function testing

Once the sensor has been attached, check that it functions
correctly.

How to test the transmitter:

– Insert the computer into the bracket.
– Lift and spin the front wheel.
– A speed should now be displayed on the computer.

If no speed is displayed, there can be several reasons for this.
The possible reasons are described in the “Trouble-
shooting” section.

Settings – wheel circumference

M1 WR

You can set the roll circumference of your wheel on the VDO
M1 WR.
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 wheels in the wheel size table
and set these in the device.

If your wheel 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 front wheel 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.
