The invention of the present application relates to a device which can be used both for exercise as well as a drive for a band saw. This has been achieved by using the bicycle as the primary source of power for a portable band saw. The bicycle can be quickly and easily mounted in the frame for the band saw. The bicycle may be stabilized so that an operator can exercise at the same time that the band saw is being operated.
