Each origin zone represents around 8000 residents living nearby. Only flows with 25+ cyclists (13+ in Scotland) shown. Flows which stay within the origin zone are not shown. Hover over a flow line for numbers. Line thicknesses remain the same at all zooms.

Colours show to-work direction

Bi-directional flows show up as grey

Flow lines go between zone centroids. In
rural areas these may be a considerable
distance from the true journey start/end.
