Portable Bicycle - Riding Performance

Riding Performance

The riding performance of portable bicycles is challenged by the need to make the bike as small and as light as possible. Rider body weight and size, and road conditions have a strong impact on design and on performance. Typically, portable bicycles intended for the East Asia market (China, Japan, Korea, Taiwan, ...) can be designed for riders lighter than 80 kg and shorter than 174 cm. Northern Europe and America require designs for riders up to 120 kg and 200 cm. City roads are generally smoother in Asian cities, but the bicycle has to be able to ride in crowded city sidewalks. Many European city streets are paved with cobblestone, so portable bicycles marketed in Europe need to cope with such a pavement. The smaller the diameter of a bicycle wheel, the higher the rolling friction and the rougher the ride, which is a challenge for portable bicycles as well as for kick scooters. New technological solutions are being studied to offer the same rolling friction at smaller wheel diameters.

Famous quotes containing the words riding and/or performance:

    Nobody dast blame this man.... For a salesman, there is no rock bottom to the life. He don’t put a bolt to a nut, he don’t tell you the law or give you medicine. He’s a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling back—that’s an earthquake. And then you get yourself a couple of spots on your hat, and you’re finished. Nobody dast blame this man. A salesman is got to dream, boy. It comes with the territory.
    Arthur Miller (b. 1915)

    Kind are her answers,
    But her performance keeps no day;
    Breaks time, as dancers,
    From their own music when they stray.
    Thomas Campion (1567–1620)
