Here is an interesting quad fixed prototype.
“It was only a matter of time ‘till we put pen to paper & drafted up the first ever Quad Fixed frame. What you see here is #1 of one. Strictly prototype & still in the development stage. This frame was handed off to Marwin “The Wizard” Ou last night. Marwin will be riding & testing it on the streets & skateparks of the LBC in the coming months. We have not yet decided if we will bring the Quad Fixed frame into SE’s 2012 line of bikes. So for now, just consider it our little pet project. If you like what you see, keep an eye out on the SE website (www.SEBIKES.com) and SE’s Facebook page (http://www.facebook.com/SEBIKES) for the frame’s progress.”
