A 3rd-coast based project putting free bicycles back on the road with a rat-rod mentality and no thought given to comfort. Assblast was originally just the name of the initial bicycle (now named "ANAL FIESTA I"), and was given to the bicycle due to the fact that with no rear tire that shit really hurts one's ass who so choses to blast that bitch down the road.
Assblast projects include =

DUALLY SCOOTER (done but broken)
AF I (incomplete)
SCREAMIN SEMEN (waiting for a tire)
AF IV (super dangerous)
