Bicycles don't have to have a functioning speedometer as a condition of their roadworthiness like cars do you would need further legislation (and in the process make cycling more expensive). Even if they were mandatory, they rely on being set up correctly and can be made innaccurate just by a change of tyre type.If cyclists are not expected to obey speed limits I expect it was because 30 was the lowest limit and few if any cyclists can achieve 30, even downhill with the wind behind
Now with a 20 limit I expect the code will be modified to include cyclists where speed limits are concerned (if indeed they are excluded at the moment) after all we expect cyclists to obey traffic lights and give way rules so it would be most strange if they were excluded from speed limits.
And breaking thirty is easy on any decent downhill.
