What modal shift to cycling do you think we could achieve in UK cities in an ideal scenario?
Answers to that question are vital to support high level ambition for active transport and wider sustainability policies in settlements worldwide.
-In UK cities such as Leeds (where the motivation for this article originated, via [Twitter](https://twitter.com/PaulChatterton9/status/1190925153322098690)) there is already a wealth of freely available data on cycling potential, based on the Propensity to Cycle Tool ([PCT](https://www.pct.bike/)) project, of which this package is a part.

This article will briefly explain how to get cycling potential data for any city in England and Wales, based on a case study of Leeds.
