Push button shift control for bicycles and the like
摘要:
A push button shift control for a bicycle and the like is provided and consists of a plurality of push buttons extending upwardly through top of a housing to be clamped typically onto a downtube of the bicycle. A locking mechanism keeps each of the push buttons in a down position when each of the push buttons is pushed in sequence to move a control cable a predetermined distance to operate gears of the bicycle. A releasing mechanism releases the push buttons so that the push buttons and the control cable can return to their previous positions.
