We know that a “seat clamp” is what holds the seat to the bike, but imagine if the seat/saddle can also be used as a bicycle lock? That’s the concept of the Saddle Lock, which was designed by Lee Sang Hwa, Kim Jin Ho and Yeo Min Gu. The idea here is to lock the rear wheel of the bicycle without needing additional locking accessories. Of course this doesn’t actually secure the bike to anything, but for those who need to grab a coffee or otherwise look to step away, the Saddle Lock can lock down the bike.
