'pedal-less' originates from the English word 'pedal' combined with the suffix '-less', where 'pedal' refers to a foot-operated lever and '-less' indicates absence.

'pedal' comes from the Latin word 'pedalis', meaning 'of the foot', and '-less' is a common English suffix indicating absence.

Initially, 'pedal' referred to a foot-operated lever, and 'pedal-less' evolved to describe something lacking such a lever.
