Hey all. I'm wondering how to make a fixie that would be better for the crappy roads in my town. I've been bitten by the bike bug and am full of ideas on different bikes for different uses. For an everyday commuter though I was thinking of one of the three below.

Really cool cruiser with a fixed hub. I also don't get the seatpost and handlebar setup, what are my options?.

These two are mtb type setups. Trackish frame with mtb wheels. Something similar would be more practical for the huge curbs and massive potholes in my area.

One more question. Are there practical mods I could do to an actual track frame to make something like the ones above?. Any info or ideas you have is much appreciated. Thanks for reading the long post too
