The thing that concerns me with the bike system is if you arrive at a station, and there isn't any room to park your bike, leaving you with the bike for longer, which means you'll be paying for more.
Why just a half hour for free though? I remember in Vienna where they have basically the same system, you could ride for free for under an hour, park somewhere, then come back to ride again. I love loopholes!
Also, nobody made a comment about this that I posted a while ago (it was at the bottom of the page):
Toll lanes proposed along SH 71 near ABIA

Even the tiniest stretches of roads can't be built free anymore (well, except Ben White at 71, thank heavens that's going to be free).
This was published on April the 1st. Hopefully the toll part was an April fools joke lol.
