The combination of a bicycle with an information-producing assembly carried thereby. A structure which is carried by one of the bicycle wheels for rotation therewith turns at each wheel revolution past a second structure which responds to provide a revolution signal, this second structure being connected with a computer which receives the revolution signals as well as timed signals at a given constant frequency. The computer includes logic and arithmetic circuits for carrying out operations such as conditioning, calculating, treating, and memorizing operations, so as to produce from the revolution signals and timed signals measurements such as a lasting measurement of the total distance traveled during operation of the bicycle and ultimately of the time which has elapsed, as well as selectively producing in connection with travel over part of a given course values such as the distance traveled or time elapsed, average or maximum speed during travel along part of the course, and also instantaneous speed at any given moment. An indicating structure is accessible to the operator for selectively indicating from the computer values such as the distance or elapsed time in connection with part of the course which is to be traveled, and also for producing a temporary display, which may be illuminated, of any one of the latter values. A source of electrical energy is connected with the above structure for assuring operation thereof at least while the bicycle is used. |
