Family gets ready for Sunday drive in Zem Human Powered Vehicle    |    Posted: July 18, 2006

With an SUV in the background, the Mullins get ready for a trip.

Their Zem is human powered, but Dean installed a small electric assist motor because children don't always want to pedal uphill.

The Mullins routinely travel with four children, one in the trailer, one in a sling, and two pedaling (when they feel like it) in the front.

Dean says his motto is "Burn fat, not oil."

As the oil begins to run out will you find yourself driving your family around in an electric assisted Human Powered Vehicle?
