The safety bicycle is a type of bicycle that became very popular beginning in the late 1880s. The first safety was invented by John Kemp Starley in 1885. "Safety's" are characterized by having a diamond-shaped frame, two wheels of identical - or nearly identical - size, and a chain driven rear wheel.

The safety bicycle was a big improvement on the previous penny-farthing design which it replaced. The chain drive, coupled with gears to multiply the revolutions of the pedals, allowed for much smaller wheels, and replaced the need for the large, directly pedaled front wheel of the penny-farthing. The safety made cycling much safer, and therefore much more popular. The same basic design of bicycle is still in common use today. The penny-farthing is an early model of bicycle, produced in England in 1870. ... Spur gears found on a piece of farm equipment. ...

Bicyclesafety is the use of practices designed to reduce risk associated with cycling.
Primary safety is the active reduction of risk; secondary safety is measures taken to mitigate the consequences of risk.
In addition to technical improvements in brakes, tyres and bicycle construction generally (for example, it is now rare for a chain to snap and throw the rider when accelerating away from a stop), there are well-understood behavioural models which actively manage the risk posed by others.
