The present invention is directed to a combination yo-yo and top device
comprising first and second yo-yo body halves, a hollow dowel element
detachably connecting one of the yo-yo body halves to the other, a ball
bearing element mounted on the hollow dowel element between the yo-yo
body halves, a first flywheel assembly having an elongated flywheel axle,
wherein the first flywheel assembly is adapted for attachment to the
yo-yo body, a second flywheel assembly adapted for attachment to the
yo-yo body, a string element having a first end coupled to the hollow
dowel element, a power element adapted for attachment to either the first
flywheel assembly or the second flywheel assembly to activate both
flywheel assemblies, and, at least one removable top component adapted to
be secured to the yo-yo body to convert the device from a yo-yo to a top.
