We’re reviewed plenty of really cool bike racks but never one that could accomodate two bikes. This is what the Michelangelo Two Bike Gravity Stand ($75) does, in style. Designed by Public Bikes, this two-bike stand leans against the wall and gravity does the rest. No attachment required. The Michelangelo Two Bike Gravity Stand works with any kind of bikes and actually looks pretty cool for such a convenient storage system.
