Supergirl's bicycle
From Tardis Wiki, the free Doctor Who reference
Supergirl owned a cyan bicycle.
During the opening of an episode of Meet That Hero!, Supergirl flew her bike in front of the Moon, creating a black silhouette of herself and the bike in front of it. When she got off of the bike in mid-air and began flying, the bike crashed to the ground in the forest she was hosting Meet That Hero! within. (WC: Supergirl Meets E.T.)
