Smart brake pad / Bicycle Accessories

Smart brake pad is a conceptual design which can avoid wheel damage caused by brake pads in terrible condition. The design has solved the riders’problems that they don’t know exactly when to change their brake pads.

The design utilizes a layer of crayon which can color the metal. When Smart Brake Pads are in good condition, they serve as usual brake pads. When they are about to be use up, the layer of crayon appears and colors the wheel, thus reminding the rider to change the brake pads. After a new pair of Smart Brake Pads are installed, the trails of crayon will soon be erased by them.
