Coincidental bike stacking.
E went to the railway station and parked her bike. I took a train later, having cycled with Y to school first. I spotted E’s bike and parked mine above it.

@ton This looks like an outer worldly bike stand! Never seen one like this before. 🚲

@odd it's simple, you engage the antigravity module and levitate up. ;) They're common at Dutch railway stations. If you pull the red grip the top stand rolls towards you and you can angle it down in front of the bottom stand, so you can lift your bike in / out.
