Be careful parking the bikes back into the bays. I've been using them for over 1 year regularly and recently was fined 150euro for apparently not parking the bike correctly. Despite waiting for the light to go green and pulling the bike back to ensure it was locked, they still said it was never parked and the bike was found 20 days later.
You need to be 100% certain the bike is correctly docked or you get fined.
