Billy Whizz, which started in 1964 (issue 1139, May 16th) as a replacement for "The Country Cuzzins", was created by Malcolm Judge. He had previously drawn "Colonel Crackpot's Circus", but Whizz was a far more interesting and enduring creation.
Judge stopped drawing the strip in the late eighties and has been replaced by various artists; primarily Vic Neill, but also Trevor Metcalfe and David Parkins (possibly!). The strip is currently drawn in a rather slapdash style by G. Hall.
Where Judge's original scores over all its imitators, though, is in the sheer variety of ways that Billy's "whizzing" was depicted, some of which are shown here. Later artists tended to concentrate on a specific visual device; blurred, spinning legs in Metcalfe's case, elaborate trails of dust from Parkins and - sadly - little more than "motion lines" from Neill (who I'm rather afraid to say took a lot of the fun out of the strip - shame 'cos I like his style as a rule).*
