Abstract: An anthropometer for the rapid and accurate measurement of dimensions of the human body required for the proper selection of a bicycle. The device includes a support having an upright portion. It also includes a horizontal measuring element adapted to bear against the crotch of a standing individual to be measured which is substantially freely vertically movably attached to the upright portion of the support. The measuring element is urged against the crotch of the individual being measured with a predetermined force to assure accurate measurement without embarrassment to the individual being measured or to the individual performing the measurements.
