[0002] In order to adapt to the diversity of roads and meet the needs of off-road, bicycles have evolved into variable-speed versions. Variable-speed bicycles install a transmission on the vehicle to achieve gear changes, and with the continuous advancement of technology, traditional mechanical transmissions are gradually replaced by electronic transmissions. When a variable-speed bicycle equipped with an electronic transmission needs to change gears, the controller on the front of the vehicle sends a control command, which is transmitted to the electronic transmission through the wiring harness. The electronic transmission makes corresponding gear changes according to the command; and the electronic transmission consumes electrical energy, which requires a battery. When the battery is dead, it needs to be charged in time to change gears normally.

[0003] However, in existing electronic transmissions, two sets of wiring harnesses are usually used to realize signal transmission and power supply respectively. In particular, an independent wiring harness is used for charging the battery, which increases the number of wiring harnesses on the bicycle, which not only increases the difficulty of wiring, but also increases the production cost. Therefore, there is an urgent need for a magnetic charging adapter cable, an electronic transmission and a bicycle to solve the above problems. Utility Model Content
