These miniature dirt bikes are absolutely ubiquitous at Kentucky Horse Park as easy runabouts when a “full-sized” golf cart would be overkill. (And yes, I appreciate the humor that a tiny golf-cart is the three-row SUV of the horse world.)
Even these tiny bikes are more commonly seen with two riders—particularly in the vicinity of the snack bar.
Passengers are invaluable for coffee-handling duties.
Helmets, mandatory when on horseback, are evidently not à la mode for minibikes.
