The rear bike gear shifting system works by using a derailleur to move the chain between different sized sprockets on the rear wheel. When the rider shifts gears using the shifter on the handlebars, the derailleur moves the chain to a different sprocket, changing the gear ratio. This allows the rider to adjust the resistance and speed of pedaling to match the terrain they are riding on. The rear gears are typically controlled by the right-hand shifter on the handlebars, with each click of the shifter moving the chain to a different gear. **
