Abstract
Abstract A mobile vehicle for training beginning skaters is provided which has a fixed handlebar and seat mounted above a straddlebar extending between the two. The straddlebar is rigidly fixed to front and rear legs which are rigidly mounted to a wide and long base comprising two horizontal transverse base bars having swivelling caster wheels at their outer ends. The rear leg extends downward and considerably to the rear. The vehicle permits a beginning skater to train in a relatively uninhibited manner with support from a fall forward by the handlebars and skate toes and support from a rearward fall by the seat.
