Hey, today I saw a "Simplex" bike. I liked it more than the Whizzers that I've seen, and I just wondered why the Whizzer were more popular than Simplex. My dad talked to a friend of ours and he said that the engines were ****, just because of the way they were built. I've never seen one restored all the ones I can find on the net are still, "barn fresh". If any of you guys has one of these or knows someone that does, I would appreciate the pics and info. Thanks!
