Take available bikes into account

[zyla]

Sometimes Ceburilo can compute a route where starting station has no available bikes, thus rendering it useless. Using nextbike data can help that.

There's 5 minutes lock to rent the same bike. (source: https://www.veturilo.waw.pl/zaprzyjaznij-sie-z-elektrozamkiem/)
As available bikes change in real-time, this could be implemented client-side as re-route suggestions.
