As a circular path for electrons a giant macrocycle with a periphery consisting of exclusively conjugation‐active units has been designed. With a diameter of 12 nm it is probably the largest synthesized, shape‐persistent, and monodisperse cyclic structure to date. In addition, the front wheel of a bicycle is shown, the 16‐fold symmetry of which inspired the design of the molecule. For more information on this molecule see the Communication by M. Mayor and C. Didschies on page 3176 ff.
