Why does the TrailTech Endurance take a few seconds to show speed changes?
With any digital speedometer, it takes two wheel revolutions (sensor triggers) before the computer can make an estimate of speed. The more samples acquired before displaying an update, the more accurate the number (at the end of a ride, the average speed number will be very accurate). For rapid stop/start riding, the digital speedometer will not display accurate numbers. If riding at a “pace”, the displayed speed number will be accurate.
