If you're a keen skateboarder this beast could give you a load of fun!
It has two castors, one at each end, and is propelled by swinging your weight side to side. I've seen a few skilful riders and have given it a try myself, but bruises on my knees, arms, butt and other projecting parts are a testament to my lack of ability! I'm also far too old (according to my wife).
I bought it on a whim from a carboot sale a year ago. It's in good condition with very little wear and tear and comes with a tailored carry bag.
