Above is a link to one forum online with some experts in Whizzers as well as other motorized bikes. I use this type of forum to learn from and share info with others about topics of interest. The top photo came from an October morning trip I took out the Apache Trail in the east valley of the Phoenix area. I am at a small Farnsworth Plaza out University Rd close to Power Rd. Below that are some more photos from that memorable 5 hour trip of some 85 miles. Not bad photography, even for a photographers son.
