Abstract
An electrically assisted street scooter includes a handlebar, a deck, front and back wheels, a battery pack integral with the deck, an electrical motor for driving at least one of the wheels, and a drive circuit for controlling electrical supply to the electrical motor from the battery pack. The drive circuit includes a switch for setting the drive circuit in a low power-mode where the electrical motor is not powered when the switch is off, or for setting the drive circuit in a drive mode where the electrical motor can be powered when the switch is on. An auto-power on circuit automatically switches the switch on when a user pushes the street scooter. An auto-power off circuit automatically switches the switch off when the scooter is not used during a predetermined duration. The level of electrical assistance is determined based on the peak value after each leg push.
