Named after the small mammals that live underground, Mole's Hide and Seek Bike Rack is a bicycle-parking device that does not obstruct pedestrians.

Mole's Hide and Seek Bike Rack hides underground, only rising above the surface when it is needed. It pops up when someone steps on the ground plate that surrounds its hole. When the Mole rack is hidden below the surface, its plate functions as a signal. It provides people with directions and information about the area – for example, the direction in which they will find a public bathroom or bus stop.

A solar panel on the top of the rack collects solar energy during the day, which is used to power the Mole’s LEDs at night. These illuminate the area, alert people to the presence of a bicycle (by glowing red), and indicate that a rack is available (by glowing green).

After a bike is parked, a fingerprint reader allows the cyclist to register their fingerprint into the system for locking and unlocking purposes. When a user’s fingerprint is recognised, the rack automatically locks or unlocks the bike.
