  • Bicycle seat sizer and positioning device
    Patent number: 9314187
    Abstract: A device for determining the distance between protruding anatomical features of a user includes a first portion having a volume of displaceable material and a second portion having at least one scale attached thereto. The displaceable material is configured to be displaced when subjected to a pressured loading to create depressions in the displaceable material. The second portion is movable relative to the first portion such that the scale can be aligned with the depressions to provide an indication of the distance therebetween. Preferably, the scale is coded for association of the distance with a desired bicycle seat size.
