On the fork there is a kind of tacho station, which on the one hand measures the speed of the bike, and on the other hand holds an acceleration sensor that measures the fork speed. Under the “speedometer” there is the computing unit that is attached to the stem - there is another acceleration sensor: these two sensors calculate the respective acceleration values, based on their location. Simply explained: The system recognizes from where and how strongly a blow on the front wheel affects. 4 Modi: Fully automatic, open, medium (by means of a lot of pressure level- platform), lock out (blocked- but still works minimally)- the fully automatic mode is divided into 5 steps- these steps can be selected simply by the driver and indicate how quickly the system should regulate to evaluate the senso.
