A manually propelled vehicle may include a vehicle body, a left drive wheel and a right drive wheel, a wheel driver that drives the left and right drive wheels, a sensor that detects a user behind the vehicle body, and a controller that determines whether the user is behind the left or right drive wheel based on a detected result of the sensor. When one of the left or right drive wheel moves backward and the controller detects that the user is behind the one of the left or right drive wheel, the controller suppresses or stops the wheel driver from driving the one of the left or right drive wheel.
