It generates electricity from turning the pedals and that become the power for the equipment placed in both of your holes and nipples. Hence the vibrations are not strong. However, if the pedaling speed drops from the speed for the set 15km for 5 seconds, the device turns the power on max on the vibrators and injects semen mixed with strong aphrodisiac in you from the tank on your back.
