Not sure if anyone can shed any light on this but my bike has been in storage for 3 months due to a house move, i took it our yesterday and could not get the speed sensor to pick up how fast i was going.

It is a wired unit and i checked the distance between the magnet and the sensor umpteen times.
Battery must be ok as it picked up my heartrate and time.
Gave it a good clean to remove any dust etc.
Occasionally it would pick up the speed but only for a few seconds every 30min or so.

Long shot but hope someone can help :)

    Try a new magnet?

    If you still have problems, VDO are very good - I sent back my 8 year old unit to them (in Germany) and they replaced it foc with a new, better model. They offer a 5 year warranty but exceeded that for me!
