ABSTRACT:
A bicycle ergometer, where with the aid of a spring balance the braking effect of a band brake on the rim of a flywheel is measured and the braking effect may be regulated. The band, spring and indicator are normally fastened to a ball-bearing fork in the hub of the wheel, thus the tightening of the band strains the bearings. The fluctations of the indicator caused by the uneven friction and the vibrations characteristic of the spring have been reduced by a hydraulic damper. In this invention the fork has been removed. The band, spring and indicator are fastened to a weight resting on the flywheel and steered by a groove on the rim of the wheel. The mass of the weight reduces the indicator fluctuations.
