This parking facility in Utrecht, which opened in August of 2019, may be the world's biggest - certainly the Netherland's biggest - holding 12,500 bikes. There are other large indoor facilities for bikes in the Netherlands, but you can't bike through them. This is a quick tour of the upper floor (the lower floor can be seen on the left).
