Two versions of recumbent human powered three wheeled vehicles are disclosed. Both are of the tadpole type with two front wheels and one rear drive wheel. Both versions lean into turns causing weight transfer toward the inside of turns to prevent rollover during turns at speed.

I claim: 1. A multi-wheeled vehicle wherein steering is derived from operator lean comprising:a) A longitudinal main frame having a seat, and at least one rear wheel;b) A perpendicular frame;c) Means for pivotally connecting said longitudinal main frame to said perpendicular frame for providing pivotal motion of said longitudinal main frame through an approximately 90 degree arc about a generally longitudinal axis;d) A pair of wheel spindles;e) A pair of steering knuckle assemblies for pivotally attaching said wheel spindles to opposite ends of said perpendicular frame establishing a pivot axis, implemented by said steering knuckle assemblies, said pivot axis of said spindles is selected to cause said spindles to rotate relative to said perpendicular frame about said pivot axis, said rotation causing said spindles to simultaneously tilt and steer while said perpendicular frame remains perpendicular to said longitudinal main frame, each of said steering knuckles including a trailing arm, said pivot axis is inclined rearward and centerward relative to said vehicle;f) A vertical arm having an upper end connected to said longitudinal frame, and a lower end, said lower end extending downward past said perpendicular frame;g) A first tie rod having a first end connected to said lower end of said vertical arm, and a second end connected to the trailing arm of one of the steering knuckles;h) A second tie rod connected to said second end of said vertical arm and to the trailing arm of the other steering knuckle.
