A vehicle-mounted display system, including a display unit and a pressure control unit. The pressure control unit is configured to enable the display unit to expand or contract; the display unit is configured to carry out the expanding or the contracting based on control of the pressure control unit.

A suspension assembly for a cycle includes a link and an indicator having a central opening. The indicator includes a first retention feature. A pivot assembly is disposed in the link. The pivot assembly includes a second retention feature. The first retention feature and the second retention feature cooperate to axially retain the indicator on the pivot assembly while allowing rotational movement between the indicator and the pivot assembly when a force threshold is exceeded.

A safety system for bicycles includes a radar, a controller, and a warning apparatus, which includes a tube, a vibrating motor, and an impact sounder. The vibrating motor includes a rotary shaft and an eccentric block. The impact sounder includes an elastic member and an impact block. The elastic member includes a first end fixed to the inner wall of the tube and a second end connected to the impact block. When the controller decides to issue a warning based on a radar signal, it outputs a control signal to drive the rotary shaft to rotate. The rotation of the rotary shaft drives the eccentric block to rotate and vibrate, and the eccentric block strikes the impact sounder to make the impact block hit the inner wall and thus generate an impact force and emit a sound. The warning apparatus simultaneously provides the bicycle rider with vibrating, impacting, and audible warning.
