Following your report of the N.S.A. Records Day, perhaps these figures for the human-propelled “2-wheeled sprinter” may be of interest to you. Compared with the 50-c.c. record they do not appear to be too much out of place.
On July 24th, 1951, Reg Harris recorded 27.7 sec. for the unpaced standing-start 1/4-mile on a single bicycle at Fallowfield track. At Herne Hill on September 1st, 1928, J. E. Sibbitt and E. H. Chambers, two amateurs, recorded 27.4 sec. on a tandem bicycle. For veteran enthusiasts, the professionals C. F. Barden and H. B. Howard recorded 28.8 sec. on a tandem bicycle at Wood Green track on August 1st, 1898, this record still standing as tandem racing has now lost most of its popularity in Great Britain.
