Code Name Ginger by Steve Kemper.

Steve had an agreement with DK to follow the development of the Segway, but the secret project was leaked to the press (the whole 'what is It?' thing a few years back), and I think Steve and Dean had a bit of a falling out.

The book came out about a year after the Segway was introduced.

For technology books in general, I recommend you look for biographies. Ken Olsen from Dec, Jobs, the Woz... just about anyone who has been tied to engineering and technology in the last few decades.
