In 1895, Curtis H. Veeder invented the Cyclometer. [1] [2] [3] The Cyclometer was a simple mechanical device that counted the number of rotations of a bicycle wheel.[4] [5] A cable transmitted the number of rotations of the wheel to an analog odometer visible to the rider, which converted the wheel rotations into the number of miles traveled according to a predetermined formula.
An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ( electromechanical ).
The "Bell Helmet Company" was established as a division of Bell Auto Parts in 1956. [2] Bell introduced its Star model, the first full-face motorcycle helmet on the market, in 1968. [4] In 1971, Bell produced the first full-face off-road motorcycle helmet. [5] Bell made its first production helmet in 1954.
John Richard Dedicoat (born 1840, Birmingham; died 1903) was the inventor of the pencil-sharpening machine, [citation needed] bicycle bell, [1] and other bicycle related items. Apprenticed to James Watt , [ 2 ] he went on to become a bicycle manufacturer and made and sold the "Pegasus" bicycle.
A machine commonly displayed as Clayton's odometer is actually one built in 1876 by Thomas G. Lowe. Lowe created his odometer to calculate the distance between villages in northern Arizona. He gave his odometer to the Deseret Museum in Salt Lake City, and it was on display with accurate information from 1876 until it closed for a period in 1903 ...
The second was the pneumatic bicycle tire, allowing smaller wheels to provide a smooth ride. An 1880 penny-farthing (left), and the first modern bicycle, J. K. Starley's 1885 Rover safety bicycle (right) The nephew of one of the men responsible for popularity of the penny-farthing was largely responsible for its demise.
The bell is a required piece of equipment in some jurisdictions. In the United Kingdom, bells on new bikes were compulsory until 1983, and again since 1 May 2011. [4]In New Jersey, a bicycle must be equipped with a bell or other audible device that can be heard at least 100 feet away, but not a siren or whistle.
Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.
