___________________________________________________________________ "Bipedalism is not a trait that uniquely evolved in humans but has occurred in five different instances among vertebrates. Twice it evolved in reptiles, first in thecodonts-the reptilian ancestors to crocodiles, birds, and dinosaurs-and second in lizards, such as the Callisaurus draconoides (a.k.a. zebra-tailed lizard). Birds could represent another instance of bipedalism but it is commonly believed that they evolved from dinosaurs. Finally, there are three instances of bipedal evolution in mammals: the marsupial ricochet form (kangaroos), the placental ricochet form (kangaroo mice), and primates and humans with their alternating gait (Snyder 1962)." - http://www.philosophistry.com/static/bipedalism.html
Since they run about on all four legs they are in fact quadripedal, not bipedal.
An animal that is a biped moves around by walking or running on two legs. This gait is characterized by a swinging motion of the legs and a push-off from one foot to the other. Bipedal animals maintain balance and coordination while in motion through a combination of muscle control and sensory feedback.
An animal that walks on four legs is called a quadruped.

Biped
A human is a biped, meaning we walk on two legs like fancy show-offs while horses use all four like the humble creatures they are. So, next time you see a horse trotting around on all fours, just remember they're the real multitaskers of the animal kingdom, unlike us two-legged humans who struggle to walk and chew gum at the same time.
The Biped stood there silently.
