This looks alot like the old Dunecycle (shown below), but this is the Tri-Sport, made in Canada – Join the great 3-wheel revolution.
The newest fun machine around! It’s here! The great new way to get out and play! Fun for the whole family! Tri-Sport’s sure, stable stance and big, low-pressure tires let you go practically everywhere – sand, snow, mud, hills…even thru thick underbrush. No gears to shift – anybody can become an expert Tri-Sport driver in no time. Ten great models to choose from. 3 hp to 21 hp. A couple of turns of a wrench – Tri-Sport is a skier too!
