VDO M6: the expandable all-rounder with altitude measurement & trip memory The VDO M6 is a true all-rounder offering all bike functions plus comprehensive altitude measurement in a single device. The three channel data transmission between the cycle computer & the sensors is entirely wireless & uses automatic pairing. The core feature of the VDO M6 is the barometric altitude measurement with numerous functions. The VDO M6 uses state-of-the-art technology & provides a broad range of altitude data: current & maximum altitude current maximum & average gradient uphill altitude gain & loss distance uphill & downhill maximum & average gradient downhill as well as annual altitude (total/gain/loss) annual distance (uphill/downhill) & maximum annual altitude for each of bike 1 & bike 2. The altitude profile can also be displayed in graph format on the large easy-to-read display. The altitude is calibrated either by entering the current altitude or by means of the barometric air pressure. The cadence kit further expands the VDO M6s functions to display the current average & maximum cadence. The top model VDO M6 offers all the technical innovations incorporated into the new VDO M-series. One particular highlight of the VDO M6 is the integrated data memory for 10 trips. This makes it possible to compare the values for several rides & draw conclusions about the training sessions completed.
