In developing the VDO M-series, particular attention was paid to creating a user-friendly operating structure & button-based function grouping. The result is a range of cycle computers that are convenient & intuitive to use & offer the renowned VDO quality. With the VDO M3 all the important bike functions such as the speed, average speed, maximum speed, ride time, ride distance, total distance, time & temperature are stored within the VDO M3 small computer housing. The integrated roadbook function is a particular highlight of the VDO M3. This separate distance counter (which counts forwards or backwards) can measure individual section distances during a ride so that roadbook routes can be perfectly followed. This makes the VDO M3 the ideal companions for mountain bike rides on any terrain. The internal trip section counter comprises a second distance counter coupled with a stopwatch to show the distance travelled over any desired period. The broad range of functions is rounded off with a low battery warning, data retention on changing the battery, an automatic start/stop function when setting off after a break & an integrated tyre table for conveniently setting the wheel type.
