A human-powered vehicle ( 100, 560 ) includes a structural frame ( 105 ) supported on multiple road wheels including driven wheels ( 110 ) each rotatable about an axle for propulsion, a seat ( 115 ) secured to the frame ( 105, 554 ) for supporting an operator, a hand crank ( 250 ) disposed above the driven wheel ( 110 ) and rotatable by hand by an operator seated in the seat ( 115 ), and a steerable rear wheel ( 120 ) operably linked to the seat ( 115 ) such that pivoting of the seat ( 115 ) about a seat pivot axis causes pivoting of the rear wheel ( 120 ) to steer the vehicle ( 100, 560 ).
