This place used to be called Peeping Bomb, but they rebranded it and called it after their main product, Airwalk bikes. These are entry-level fixed-gear bikes made be a Taiwanese company. If you're in the market for a really attractive, hard-working machine that will get you around town fast, looking amazing, then Airwalk is a solid bet. They'll build you a bike for about 3000rmb, everything, down to the spokes and the cables, come in a rainbow of colors. The store also sells some hip-hop clothing, big Ts, shorts, that stuff. T-shirts aren't so cheap, around 300rmb and up.
