Sulky

The modern racing sulky has shafts that extend in a continuous bow behind the driver's seat, with wire-spoked "bike" wheels and inflated tyres.

Historically, sulkies were built for trotting matches and made from wood with very tall wheels and almost no body, just a simple frame supporting a single seat.

[3] Such vehicles were called "sulkies" because they were "said to have been chosen by unsociable people fond of their own company or fits of sulking".

When it rains, or the track has excessive moisture, trainers and drivers are required to put plastic mud flaps on the back of the wheels.

In 1990 the asymmetric sulky was introduced into North America, winning seven of its first nine starts at Freehold, NJ.
