Stage of Development

Source: http://www.revopower.com

From a raw idea in early 2003, the team of engineers at RevoPower has developed breakthrough technology to incorporate an entire engine and gear train into the width of the normal bicycle wheel. Many early sceptics are now believers in the product.

A number of prototypes have been constructed and tested, and the final design is close to completion. Extensive testing and refinement are planned prior to proceeding with high volume manufacture.

A number of patents are pending, the first of which was issued in early 2005 (see Technology : Patent Protection).

The product should be available in early 2007 with an expected MSRP of $399.
