These are my favourite: https://i.imgur.com/jpF0eZV.png https://i.imgur.com/jpF0eZV.png Slightly more complex design, but easy to lock, easy to park, bike doesn't fall over, doesn't damage the paint on your frame, fairly compact if you have multiple bikes. They're pretty ubiquitous where I live in the Netherlands; although some stores have really crappy "wheel-only" stands like in the thread.
