RevoPower, Inc. developed The Wheel, a bicycle wheel with a completely self-contained engine and gear train that transforms almost any bicycle into a motor-assisted vehicle. The company needed a 3D CAD system to complete the design and overcome the difficult challenges associated with compressing the engine and gear train into a confined space between the forks of a bicycle and producing design visuals for use in securing funding from investors.
