It's illegal on quite a lot pavements on the UK though no? Or have I missed something? Rarely enforced for sure.
According to:
http://www.bikehub.co.uk/featured-articles/cycling-and-the-law/
"The primary legislation which makes cycling on a footway an offence is
section 72 of the 1835 Highways Act, this provides that a person shall be guilty of an offence if he 'shall wilfully ride upon any footpath or causeway by the side of any road made or set apart for the use or accommodation of foot-passengers or shall wilfully lead or drive any carriage of any description upon any such footpath or causeway.' "
So, as I read it, unless you're a child under the age of criminal responsibility (10 in England and Wales), cycling on footpaths next to a road is illegal throughout the UK - even in Somerset. Cycling on footpaths away from the roadway may, as I understand it, be legal.
However, in 1999, then Home Office Minister Paul Boateng issued a letter stating that:
“The introduction of the fixed penalty is not aimed at responsible cyclists who sometimes feel obliged to use the pavement out of fear of traffic and who show consideration to other pavement users when doing so. Chief police officers, who are responsible for enforcement, acknowledge that many cyclists, particularly children and young people, are afraid to cycle on the road, sensitivity and careful use of police discretion is required.”
So if someone is scared of the road, I guess it's possible to make that argument in a court of law, LOL. But as well as being 'wussy' (as the Yanks say), it's a pretty funny defence, considering the fact that footpath-cycling is more dangerous than roadway cycling.
My 9 year-old daughter cycles on the road here in the US - just today, she rode with me on a 6-lane highway. When I asked her a minute ago what she thinks about sidewalk cycling, she opened her eyes wide and said "I think it's dangerous and they're kinda stupid for doing it."
