I don't think you need a licence to ride any sort of bike you should just buy a bike and ride it its not like cars where you need licence's because with bikes you can just buy it, ride it as there is no place at all to buy real bike licences. If somebody has told you you need a licence to ride a three wheeled bike you shouldn't have to for ANY bike.
