  • Publication number: 20160096574
    Abstract: A tiltable motor tricycle as in the present invention comprises a front part and a rear part. The front part comprises a front frame, a front fork, a front wheel attached to the front fork, a steering bar, and a seat. The rear part comprises a rear frame, one pair of laterally spaced rear wheels. The front frame is connected to the rear frame rotatably around an axis line which points at the ground contact area of the front wheel and therefore the front part can tilt right or left around the axis line without affecting the position of the rear part. The rear frame has two footrests at two sides of the tricycle. The tricycle further comprises a motor and a power source. When in operation, the rider of the tricycle seats on the seat with two feet stepping on the footrests of the rear frame to keep balance and can tilt the front part of the tricycle around the axis line to maintain balance in response to road condition, speed, or turning while the rear part with two rear wheels remain stable.
