An improved personal propulsion device that generally imparts thrust directly to the user. The device allows hands free control of thrust magnitude and direction so both hands can grasp and control bicycle handlebars and brakes, watercraft paddles, ski poles or other apparatuses. The device is adjustable vertically, on the users' back, higher to allow sitting in a canoe or wheelchair and lower for standing on skates, skis, kick scooters etc. A user on a bicycle may prefer to lean forward for comfort and aerodynamics, a device adjustment compensates and delivers level thrust. A user on a snowboard or skateboard stands oblique to the direction of travel, a device adjustment allows in line thrust. Both users' hands and arms are free to balance, protect others by pushing off or break a fall. The present invention can be provided as separate modules that allow interchangeability and use with a direct drive mechanism.
