How you ever wondered how far away can you leave a Nextbike loaner bike from one of its stations, but have it still count as left on the station to avoid paying the fee?
Well, now you can find out.
$ git clone https://github.com/karolba/nextbike-bike-station-distance
$ cd nextbike-bike-station-distance
$ npm install

For Wrocław, it seems that the maximum distance is about 100 meters - bikes to stations closer than that appear from time to time (as can be seen on the screenshot) but there's always only a few of them - I assume those are some sort of flukes.
