Abstract
An exercise bicycle configured to provide fan-based resistance and a fan wheel thereof are disclosed. The fan wheel includes a hub and a plurality of vanes. The hub includes a pivot portion and a plurality of mounting portions. The mounting portions are arranged in an annular manner around a center defined by the pivot portion and each have a groove. Each vane includes a connecting end inserted into a corresponding one of the mounting portions and fixedly connected to the corresponding mounting portion by a plurality of fasteners. The fan wheel is thus easy to manufacture and assemble.
