Some more useful information:
The heatmap contains data collected from 2015 until now. It's on our roadmap to also add timestamps to the heatmap & open data.
The actual heatmap is real-time updated. The data behind the heatmap will be updated on a daily basis.
As we want to protect the privacy of individual cyclists, tracks only appear on the heatmap if at least 3 different cyclists have cycled on a specific road segment.
