Joint work of the HIS and the ADFC Main-Kinzig:
The 1000-meter-long measuring section begins at the ship's landing stage at the wooden seats. The start and finish (under the Steinheimer Bridge) are clearly marked on the paved path.
The ADFC uses information boards to describe how to calibrate (check) the accuracy of the speedometer.
At the start of the measuring section, the front wheel must be stopped on the marking and the wheel speedometer must be set to zero. Then you have to drive down the exactly 1000 meter long section as directly as possible (but please take into account the other road users) and stop on the second white line at the destination. Here the speedometer should show exactly 1000 meters. If an adjustment is necessary, the ADFC will help with a QR code on the information boards, which refers to the ADFC homepage with calculation tips via smartphone contact.
Most of the wheel speedometers sold are not considered to be one hundred percent exact. Because the included calculation tables only deal with the rim size with 26 or 28 inches, without taking the thickness of the tire into account. But it is always thicker on mountain bikes than on racing bikes. City councilor Kowol, who is almost always on the bike when on duty, sees the new route marking as a service for joggers. Because they can now always stop their 1000 meter time on Steinheimer Mainuferweg.
