Claim 4:
5. The vehicle of claim 1, additionally comprising:
the handlebar of the handle assembly actuated by the rider's arm with a right steering input force in a right steer direction and actuated by the rider's arm with a left steering input force in a left steer direction, with the right steer direction and the left steer direction substantially perpendicular to the tube of the frame assembly;
the right steering input force and the left steering input force transferred from the handle assembly to the tube assembly, and transferred from the tube assembly to the mount assembly;
a tie rod group is coupled to the mount assembly and the tie rod group includes a rod top end and a rod bottom end and the tie rod group moves upward and downward along an arcuate rod path;
the right steering input force from the rider's arm causes the mount assembly to make an upward pivot about the pin, and a left steering input force from the rider's arm causes the mount assembly to make a downward pivot about the pin;
a bell crank is coupled to a bell crank assembly, and the rod top end of the rod group is coupled to the bell crank of the bell crank assembly;
the bell crank assembly is free to pivot about a central longitudinal axis of a bell crank shaft, the bell crank shaft having a front crank shaft end and a back crank shaft end, with the front crank shaft end supported within a front plate of the frame assembly, and the back crank shaft end supported within a back plate of the frame assembly;
an upward movement of the rod group causes the bell crank assembly to oscillate in a first steering direction about the central longitudinal axis of the bell crank shaft, and a downward movement of the rod group causes the bell crank assembly to oscillate in a second steering direction about the central longitudinal axis of the bell crank shaft;
the bell crank assembly has a crank bolt, and the crank bolt is coupled to the top end of the tie rod group at a front end of the bell crank assembly, and the bottom end of the tie rod group is coupled to a steering crank bolt of a steering crank assembly by a steer ball;
a steering boss of the bell crank assembly is mounted on the bell crank shaft of the frame assembly, and with a steering group that includes the steering crank assembly free to pivot about a central longitudinal axis of the bell crank shaft; and
a right steer wheel assembly turned and a left steer wheel assembly turned by a crank oscillation of the bell crank assembly in the first steering direction about the central longitudinal axis of the bell crank shaft and in a second steering direction about the central longitudinal axis of the bell crank shaft, the oscillation of the bell crank assembly transferred by the tie rod group to cause oscillation of the steering group, the oscillation of the steering group transferred by a right tie rod group to a right spindle group of a right steer wheel assembly, and the oscillation of the steering group transferred to by a left tie rod group to a left spindle group of a left steer wheel assembly.
