US D643887 S1
An apparatus and method for determining the power of a user of an exercise cycle by measuring an RPM and resistance level achieved by the user in combination with a predetermined relationship. The RPM may be measured by sensing the rotation of, for example, a driving wheel or flywheel of the exercise cycle. The resistance level experienced by the user may be varied by an eddy current braking system. The eddy current braking system may include a pair of magnets that sweep across the face of the flywheel to thereby vary the experienced resistance level.
The broken lines illustrate portions of the exercise bike which form no part of the claimed design.
