Think they were very late 90s early 00's. Me mate Parksy has one still, I thinks its actually Kye Fortes old ride - he gave it to Parksys little brother to do a flip on or something and just let him keep it as he didnt have a ride, he past it onto older Parksy. Nick from Whitby used to ride one - he killed it, to be fair Nick would probly kill an STA fairly quick too, haha.
