VDO M4 Wireless Bicycle Computer

For those who set their sights high: the VDO M4 precisely measures the altitude and permanently displays the current altitude data. The four-part display offers the most important bike functions and even has a backlight.

Living the high life
Measurements at the highest level: thanks to its precise barometric measuring function, the VDO M4 displays the most important altitude functions – from the current altitude through the maximum gradient downhill to the altitude gain/loss for the year. The altitude data for the current trip can also be viewed at the push of a button.

A clear view
High levels of functionality need a clear overview and therefore clear structures; the space for the diferent informations is clearly defined and values together with the full text description. Efficient structure on a backlit display and therefore plenty of information at a glance.

Navigator
Road book ready: the navigator is a completely independent trip distance counter. Simply define a value and the VDO M4 will count up or down from it.
