Plural form of bobsled; small sleds designed for racing down icy tracks with a team of athletes.
From bob (to move with quick jerking motions) + sled (a vehicle for traveling on snow/ice). The design was inspired by combining features of toboggans with steering mechanisms in late 19th-century Alpine regions.
Modern bobsleds are engineering marvels made from materials like carbon fiber and fiberglass, weighing as little as 374 pounds to maximize speed while maintaining the minimum required weight—engineers constantly hunt for lighter materials.
