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

'bicycle' transformed into the colloquial term 'bike' in the late 19th century, eventually becoming the modern English word 'bike.'

Initially, it meant 'a two-wheeled vehicle,' and this meaning has largely remained the same in modern usage.
