Abstract: A bicycle bell includes a fixing seat on a pipe clamp, a bell cover, and an elastic support. The elastic support has two curved arms and a horizontal section. The two curved arms extend upward from two ends of the horizontal section. The two curved arms have engaging ends extending outwardly and laterally. The horizontal section is mounted to the fixing seat. The engaging ends are connected to the bell cover in a snap-on manner. In the bicycle bell, the fixing seat and the bell cover are assembled through the elastic support. The elastic support is a relatively flexible medium with poor energy conductivity, so that to the vibration amplitude of the bell cover is large, the energy loss is small, and the vibration is longer and louder.

Abstract: A bicycle inductive lock included a housing, a lock body, and a control circuit device. An annular latch and the lock body are disposed in the housing. A back cover is configured to close the housing. The annular latch has a first engaging groove, a second engaging groove and a third engaging groove. The lock body includes a first baffle that can be engaged in the first engaging groove or the second engaging groove, a second baffle that can be engaged in third engaging groove, and a speed reduction motor having a lever. The lever includes an angle control block and an eccentric paddle. The control circuit device includes an induction unit and a key fob. The key fob is configured to generate induction with the induction unit for transmitting a signal. With the above configuration, the bicycle inductive lock can sense the signal to be locked or unlocked.
