Abstract
A roller skate has an odometer supported on a bracket located in the space between the rear wheels of the rear truck, the bracket being affixed on the truck by a U shaped shackle and shackle nuts. The odometer may be electronic, with digital display in a magnifying window and actuated by a magnet on a rear wheel. It may also be mechanical, actuated by a friction wheel rotated by a skate wheel and movable into and out of contact by a set screw or lever and spring arrangement. The odometer can be read by raising the heel after skating.
