This was definitely the bike of my childhood era, and recall the advertisements for them as top of the cycling chain trend. However, riding these stunt performers uncomfortable as well as hazardous! - tried riding up a steep hill near a railway track and do a back wheel turn when I was 11 in 1984, and came flying back down the hill, bike in a different direction than me. They were often too small to do any creative stuff, and the boys used to throw them in the canal once they lost interest.
