ABSTRACT:
An exercise bicycle wheel comprises a pair of facing fly wheel halves. The flywheel halves include spokes which extend outwardly from a hub portion and terminate in concave rim portions which face one another. When the two halves are joined, the rim portions define a water tight cavity. This cavity is filled with a heavy material which is initially flowable and which sets in the cavity. Preferably the mixture includes hematite chips, magnetite powder, hydrated lime, portland cement, a water reducer, and water.
