These 'vehicles' help us get around, but here's a hint: They're people-powered. We use our arms and legs to roll or glide ourselves - or others - from one place to the next. Look at the photos, read the clues, and see how far you can travel.
1. Your first set of wheels probably came with a brake - and a buckle. But the brawn power came from your parents. They have two English designers to thank: One for inventing it in 1773; the other for creating the lighter, collapsible model in 1965.
2. It was called a 'wooden ox' or a 'gliding horse' by the ancient Chinese. The largest ones, pulled by donkeys, could carry six children. Today, a kid is more apt to create and race one, rather than ride in one.
3. Now, the sturdy trike is mainly used by tykes. But a larger version first gained popularity among adult riders in Britain in the 1870s. Woman, confined by long dresses, gave it three cheers for balance.
4. Some say these have been around twice as long as the wheel - for 10,000 years. Stone Age folks in Scandinavia glided on wooden ones for hunting and traveling. Until the 1970s, these were still made of wood, and the poles, bamboo. Modern ones offer better traction.
5. After seeing a pair of folding chairs atop a wheeled dolly, American Sylvan Goldman invented this in 1936. Shoppers could carry more goods and take their kids for a spin.
6. This lightweight, aluminum device on wheels became all the rage a few years ago. The airplane-grade metal can support 1,100 pounds without bending. But that's nothing compared to its much-hyped, high-tech cousin named 'Ginger,' which uses slight body movement to travel.
7. It dates back to antiquity, but it took until the 1930s for it to became popular in the United States. That's when Italian-immigrant Antonio Pasin rolled out his now-famous 'Radio Flyer,' named after the fascination with the newly invented radio and the wonder of flight.
8. Scandinavians were also the first to glide on these, about 3,000 years ago. But the blades were made of carved reindeer jaw bones.
9. It has a bow, a stern, and a keel line, but don't call it a canoe. Its name stems from Greenland's Eskimo word kajakka, or 'small boat of skins.' The name you know is a palindrome.
10. It helps propel what the native Americans called a kenu, meaning dugout. The kenu used to be made of carved wood, but now it comes in fiberglass, plastic, Kevlar, and more.
11. This small toy is for tots, but it has the same name as another, much larger toy: a Ferris wheel.
12. They look a bit like tennis rackets, and may have been used 13,000 years ago by the people who crossed over the ice bridge between Asia and North America. In 1758, a battle during the French and Indian War was fought on these.
13. Two hockey-mad, college-age brothers from Minnesota invented these in 1978. The devices helped the men train during off-season. Today, it is one of the fastest-growing sports in the US.
(1) Baby stroller. The inventor of the baby carriage is William Kent, and Owen Maclaren came up with the modern model; (2) Wheelbarrow. When one person walks on his/her hands while another person carries his/her legs, it is also considered a wheelbarrow; (3) Tricycle; (4) Cross-country skis; (5) Shopping cart; (6) Scooter. Ginger, which is battery-powered, is also called a Segway Human Transporter. It was unveiled in December 2001; (7) Wagon (the handle is shown); (8) Ice skates; (9) Kayak; (10) A paddle for a canoe; (11) Big Wheel; (12) Snowshoes; (13) In-line skates.
