Oserick Bernard "Ossie" Nicholson (1910 – 9 November 1965) was an Australian cyclist who twice held the World Endurance record for distance in a calendar year.

He competed on both road and track, as was typical of Australian cyclists of the era such as Hubert Opperman and Richard Lamb.

[1] In February 1930 Nicholson rode 55.5 miles (89.3 km) to break the Australian one hour motor-paced cycling record, previously held by Opperman.

[3] In September 1930 Nicholson broke the record for Canberra to Melbourne completing the 417 miles (671 km) in 26 hours 19 minutes.

[8] In stage 2 there was a crash at a railway crossing a few miles from Penshurst involving Nicholson, Joe Buckley and Bill Brewer.

[10] Nicholson rode in the 1931 Tour de France in a combined Australia/Switzerland team including Opperman, Lamb and Frankie Thomas.

[1] In 1911 the weekly magazine Cycling began a competition for the highest number of 100 mile rides or "centuries" in a single year.

[13] In 1932 the record for the greatest distance cycled in a single year was set by Arthur Humbles of Great Britain with 36,007 miles (57,948 km).

[13] Nicholson rode more than 100 miles (160 km) on every day and in doing so broke the record for the highest number of consecutive centuries, held by A.R.
