Abstract
A roller-type bicycle trainer includes a frame and a series of rollers that are configured to support the wheels of the bicycle. At least one of the rollers is formed of electrically conductive material, e.g. aluminum, and a magnetic resistance arrangement includes one or more magnets that are spaced from the electrically conductive material in order to create an eddy current resistive force that resists rotation of the roller, upon rotation of the roller by operation of the bicycle. The magnetic resistance arrangement includes an adjustment feature for adjusting the position of the one or more magnets relative to the roller, to vary the strength of the eddy current resistive force and thereby the degree of resistance to rotation of the bicycle wheel.
