Here's a couple variations of Crazy Frank fenders that I found very interesting. This one looks like it may be a modified original, or possibly even a one-off custom version. Either way, it's really cool!
The white seat is awesome.
This one is wild. I have no clue what those mounts would fit. They have a real strange angle, and it looks like the top taillight mount was cut off and relocated right on the fender; eliminating the plate mount. Again, this could even be a custom take on a classic.
This is someone's bike on the Jockey Journal, and it sports the elusive rigid Crazy Frank. Subtle beauty, and I'm diggin' the backrest.
Here's a weld-on version for a rigid frame.
This is a prismic Frank that Justin from AZ found and for scored for dirt cheap, and sent me a picture of. I've only seen 2 modern pictures of these (this one and mine), and a couple old magazine scans of them.
Craze's Born Free Pan sporting a rigid Frank and leaf struts flat out rules.
Looks like a total custom job but it reminds me of a Frank. The integration of the Master Craft light is so awesome.
