"Bicycles are, in law, carriages (as a consequence of the Taylor v Goodwin judgment in 1879) and should be on the road not footway. (Technically speaking, a ‘road’ is a ‘carriageway’).
The DfT view, from discussions with Home Office, is that the law applies to all but the police can show discretion to younger children cycling on the pavement for whom cycling on the road would not be a safe option.” (See, event the Department for Transport uses the word ‘pavement’).
The age of criminal responsibility is 10 so, technically, only children below this age can cycle on footways without fear of redress."
