Christened the Cyclisk, two California artists, Mark Grieve and Ilana Spector, built this obelisk made entirely out of (unusable) bike parts in Santa Rosa. According to Inhabitant (via Wired), who have other images of the artwork, "the monument is an ode to bike culture constructed from 340 bicycles and one tricycle."

The piece was unveiled on August 21 along Santa Rosa Avenue (right in front of Good Stuff Auto). It's made out of recycled bicycles, standing 60 feet tall.

Also, why can't San Francisco have one of these? Hrumph.
