Mutant bicycle jaunting club and tallbike youth brigade

Madeline sez, "A mutant bike collective in Portland, OR that makes some really awesome bikes - tallbikes, longbikes, tandem bikes, et cetera - out of scrap parts and then rides them around in costume and/or while setting them on fire. Makes me want to go to a welding class and get my ass on a CHVNKed bike!" Link (Thanks, Madeline!)
