Instructions
Stand behind the bicycle, placing one foot on a small peg attached to the main body.
Push the bike forward, gaining enough speed to pull yourself up onto the saddle. This takes practice: the large wheel generally stands at shoulder-height and the seat sits atop that.
Peddle away, but be cautious of any bumps, stones, or other impediments in your path. Tripping over the handlebars is not only easy, but painful.
Use the handlebars to turn. Do not lean into the turn: sit as straight as you can.
To slow down, pedal backwards while simultaneously applying the brakes affixed to the handlebars. When going downhill, rest your legs on the handlebars (as the pedals spin independently). This position places your weight as far back as possible, and may also allow you to land on your feet if the bike falls forward - but certainly does not allow you to slow down.
To disembark, allow the bike to slow. Throw one leg back over the seat to one side. The bike will fall to that side. Catch yourself.
