To provide an electromotive power assisted bicycle enabling an aerobic exercise with a light weight and simple mechanism, an electromotive power assisted bicycle 1 comprises a pedal effort detection means for detecting a pedal effort (99, 126), a drive unit 13, a force combining mechanism for transmitting a rotational torque of a speed reducing unit to a drive shaft, and a heart rate detection sensor 254. The drive unit 13 comprises an electric motor 37 and a speed reducing unit 35 having an electromagnetic clutch 250. In a mode enabling the aerobic exercise, if the detected pedal effort is higher than the pedal effort level enabling the aerobic exercise, the drive unit 13 drives the electric motor 37 under the condition of the electromagnetic clutch 250 being engaged and thus assists the pedal effort with the electric force. If the detected pedal effort is lower than said pedal effort level, the electric motor is turned off under the condition of the electromagnetic clutch 250 being engaged, and thus applies a loading force to the pedal effort by the rotational resistance of the motor. The pedal effort level can be adjusted in response to the detected heart rate of the rider.

The present invention is directed to a wheeled luggage item with an ergonomic telescopic handle assembly. The ergonomic telescoping handle assembly of the present invention allows a user to use the luggage using just one hand. Furthermore, the ergonomic telescoping handle assembly shifts the weight of the bag onto the bag, rather than the user's arm, reducing strain on the user's arm, and it provides for a greater space between the user's heel and the bag, reducing the chance that the user will kick the bag while walking. Finally, the ergonomic telescoping handle assembly of the present invention is stored compactly within the luggage, maximizing the volume available within the luggage for storage of personal items.

In accordance with the present invention a mono-wheel vehicle is provided. The vehicle includes a housing with an inner circumference. A wheel is connected to the housing such that the wheel is able to rotate independently of the housing. The wheel has an outside portion that makes contact with a surface. A motor mechanism is provided for rotation of the wheel. Gyroscopic forces acting on the rotating wheel maintain the vehicle in a substantially upright position such that the vehicle is able to travel along the surface in a first direction. A platform connected to the inner circumference of the housing is pivotable in relation to the housing to causes a change in a center of gravity. The change in center of gravity causes the gyroscopic forces acting on the vehicle to turn the vehicle towards the changing center of gravity in order to maintain the vehicle in a more upright position.
