Had to tell you guys something funny. I manage a 55 and older senior home association in Bothell Washington called Wandering Creek. After building my Whizzer the obvious place to make my test runs was within the walls of our 300 home gated community. As a property manager I have the unfortunate duty of writing violation letters to up-hold our covenants and bylaws, because of this I was quite reluctant to run my non-mufflered Whizzer in the Park. Its been a couple of weeks of riding around becoming familiar with how the bike works mechanically and getting everything how I want before painting. During this time I cant tell you how many residents have run out into the street or stopped me in their car and begged me for information regarding my machine and the new Whizzers. Not one of these residents including members of the board of directors has once mentioned the obvious fact that its loud, infact I usually hear a positive remark about how good it sounds. Many of our residents have disclosed to me their regrets about never purchasing a kit as a child and they're so happy to hear that the company is still manufacturing them. Its true, young and old, everyone loves a Whizzer.
