'bike' originates from the word 'bicycle', which is derived from the French word 'bicyclette', where 'bi-' meant 'two' and 'cycle' meant 'wheel'.

'bicyclette' transformed into the English word 'bicycle', and eventually became the modern English word 'bike' as a colloquial abbreviation.

Initially, it meant 'a two-wheeled vehicle', and over time it evolved to also mean 'to ride a bicycle'.
