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:
“Commuter—one who spends his life
In riding to and from his wife;
A man who shaves and takes a train,
And then rides back to shave again.”
—E.B. (Elwyn Brooks)
“The value of old age depends upon the person who reaches it. To some men of early performance it is useless. To others, who are late to develop, it just enables them to finish the job.”
—Thomas Hardy (1840–1928)
