A motorized tricycle comprising:
- a frame comprising a front portion and a rear portion, the front portion extending along a longitudinal axis of the motorized tricycle, the rear portion comprising a first leg and a second leg, each of the first and second legs extending outward from the longitudinal axis and terminating in a respective free end;
- a seat connected with the frame;
- a front fork assembly connected with the frame, the front fork assembly comprising a first support, a second support, and a front wheel, the front wheel being positioned between the first and second supports;
- a first rear wheel connected with the first leg and a second rear wheel connected with the second leg, each of the first and second rear wheels configured to rotate;
- a motor operably configured to drive the front wheel;
- and
- a battery configured to provide electric power to the motor;
- wherein, with the front wheel and first and second rear wheels on a flat horizontal surface, an elevation of a topmost point of the battery is lower than a topmost point of the front wheel.
