Abstract: An accessory adapted to be mounted to a bicycle having the capability of generating audible voice messages based on various parameters sensed by the accessory. The bicycle accessory includes sensing means adapted to be mounted to a bicycle having at least two wheels for generating a signal relating to an operational parameter of the bicycle, input means mounted to the bicycle for allowing the rider to make a request for the current state of the parameter, and means for determining the current state of the parameter in response to the request made by the rider, the current state of the parameter being determined by a microcontroller based upon at the signal generated by the sensing means. The accessory also includes means for generating an audible voice message relating to the current state of the parameter in response to the request made by the user.
