Motorized running cycle
A running bike is to be operated selectively with and without power. The running bike includes a front fork rotatably engaged with a front wheel, a rear fork rotatably engaged with a rear wheel, a handlebar coupled to the front fork for steering the running bike, a frame extending between and connecting the front fork and the rear fork, an electronic controller coupled to the frame, and a drivetrain assembly coupled to the frame and in communication with the electronic controller. The drivetrain assembly includes an electric motor configured to selectively drive the rear wheel. A battery selectively provides power to the drivetrain assembly. A clutch is coupled to the handlebar and is in communication with the electronic controller. The clutch is configured to be actuated by an operator to proportionally increase or decrease power to the drivetrain assembly electronically.
