7791 Ebicykl           Discovered 1995 Mar. 1 by M. Tichy at Klet.
Ebicykl is a traditional holiday activity, since 1984, of a group of astronomers, who bike around the Czech and Slovak Republics to visit various observatories. Ebicykl is a symbolic word combining bicycling and Ptolemaic epicycles.
