OpenBikeSharing lets you find shared bikes available in your city (around 400 cities, 38 countries). Select your bike network, find some stations in the list or on the map (OpenStreetMap) and you're good to go! Data is retrieved from the <a href="http://api.citybik.es/v2/">CityBikes</a> API. <a href="https://f-droid.org/packages/fr.fdesousa.bikesharinghub/">BikeSharingHub</a> is the continuation of this app.
