A lad on the site I work on has bought one of these. (£250 ) It took them a few days & falls to get the hang of riding it, but they are now whizzing along. They look tricky to balance on at the start. You lean forward to go to full speed. At the higher speed, they appear to be easier to balance on. Top speed up to 12.5 mph, range up to 24 miles. Have you seen many in the UK?
