One of the classic step-through frame types out there is called a mixte. In a mixte frame, the top tube of a traditional frame is replaced with a pair of smaller tubes running from the top of the head tube all the way back to the rear axle. And though this frame was most likely intended for the ladies, I'd totally rock this particular fixie mixte dubbed a Soma Buena Vista from Renaissance Bicycles. I'm diggin' its leather grips, seat, pouch and toe clip straps. Most awesome is this whip's straight up wooden rims. Bottom line, I'm man enough for this mixte.
