The days of Mom and Dad running anxiously behind their child’s first bicycle may be over.
A new trike-bike design lets kids learn to ride on their own by giving them three-wheel stability at low speeds, while letting them experience the balanced freedom of a two-wheeler at high speeds.
At rest, the thing looks like a tricycle with crooked wheels. But as the rider gains speed, the back wheels fold in to become more like one wheel. As the rider brakes, the 16-inch rear wheels open back up to prevent tipping over.
Shim, a consumer electronics researcher, developed the toddler bike – called SHIFT – with two of his students. The design won the $15,000 first prize at the 9th International Bicycle Design Competition in Taiwan, beating out 853 entrants from 56 countries.
Other entries included a bike that converts into a shopping cart, another that moves by a skiing motion, and one for walking the dog – with a foldout seat when the pooch gets tired.
