Abstract: A medical gymnastic treadmill is disclosed to include two handrail assemblies each having a horizontal top rail a plurality of screw rods pivotally supported on the base frame of the treadmill body, vertical tubes respectively coupled between the top rail and the screw rods, a reversible motor, and a transmission mechanism coupled between the reversible motor and the screw rods for rotating the screw rods to move the tubes and top rails of the two handrail assemblies to the desired elevation at the same time upon rotation of the reversible motor.

Abstract: An exercise pattern control method and system for connecting rod locus-type exercise apparatus that establishes an exercise physiology database, an exercise resistance pattern database, and an exercise locus database. Based on the exercise resistance pattern settings and locus exercise pattern settings along with the sensed user heart beat, leg angle speed, and connecting rod length, and other relevant figures so archived, a controller then calculates and processes all the database data and figures to accordingly control the length extension of the connecting rod relative to the current physiological condition of the user. As such, the present invention enables the exercise apparatus to have an operational means of locus configuration to effectively match the physiological condition of the user, thereby achieving utilization convenience, safety, and enhanced exercise efficacy.

Abstract: An electrical bicycle includes a front body unit, a rear body unit and a pivot coupler unit which couples the front body unit and the rear body unit. The coupler unit enables the front body unit to be turned relative to the rear body unit when the rider turns his or her body to shift his or her center of gravity.

Abstract: A charging device for charging an electric bicycle includes a charger which is received in the trunk of a vehicle and electrically connected to the battery of the vehicle by a conductive wire. A wire extends from the charger and is detachably connected to the rechargeable battery of the electric bicycle which can be received in the trunk or carried on the vehicle by a bicycle carrier attached to the vehicle. The conductive wire has the first end connected to the charger and the second end having an adapter which is received in the cigarette lighter receptacle hole of the vehicle.
