Bryans started road-riding on a BSA Bantam when working as a sixteen-year-old apprentice fitter. He entered his first race, the 1959 Tandragee 100, on a borrowed Ambassador 199 cc. For the 1960 season, he fitted a Triumph Terrier 150 cc engine to his Bantam frame, winning the 1960 Irish 200 cc Championship.

For the 1961 season Bryans then progressed to a 1958 350 cc Manx Norton provided by sponsor James Wilson, an insurance broker, further-learning his skills in company of established racers Tommy Robb, Dick Creith and George Purvis. In 1962, Bryans first entered the Isle of Man TT and later in the Ulster GP was placed ninth in 350 cc class riding his Wilson-Norton and tenth in the 500 cc class on a Reg Dearden Manx Norton.

In December 1962, Bryans arranged to ride Joe Ryan Nortons during 1963, when he was first noticed by Jim Redman at the Ulster GP. Bultaco signed Bryans after 'guest riding' their machines in Spain, but allowed Bryans to take advantage of a later offer from Honda to ride works machines in 1964, during which he was placed second in the 50 cc class and third in the 125 cc TT races. In 1965, Bryans won three races along with two second-place finishes to win the 50cc world championship for the Honda factory racing team.

After a short illness Bryans died at his home in Scotland at age 72 on 6 August 2014.
