The sad thing about concepts is that they often remain just concepts. We suspect the above Saddle Lock Bike by designers Lee Sang Hwa, Kim Jin Ho and Yeo Min Gu will receive the same fate.
This bike might just look like it has a set of cool-looking rims, but those rims are actually an innovative shock and tire system designed to maximize performance! The tire remains firm during normal road condition. However, when it runs on hills or over rocks, the tire and spring module bend to bear the brunt of the force. This increases both the damping and traction for the tire, resulting in a smoother, safer, more controlled ride.
