People training to race a sulky—a light, one-man, two-wheeled racing
gig pulled by a horse—often suffer from bad backs. But now Regal
International of Padstow, New South Wales, has developed a suspension system for
the small vehicle that uses springs and hydraulics similar to those found in
cars. The suspension soaks up the bumping and jarring that riders experience
during training and makes for a much smoother ride.
