Disclosed is a system for supporting a fore-and-aft wheeled vehicle in a generally upright stationary position, comprising a pair of laterally extending support legs independently moveable between a raised retracted position permitting normal motion of the vehicle and a lowered ground-engaging position, an operating lever responsive to user input to generate separate control inputs for displacing said respective support legs so as to permit independent movement thereof, actuator mechanisms responsive to the respective control inputs for displacing the support legs between the ground-engaging and retracted positions in response to user input.

In a tricycle having a longitudinally extending frame supporting a front wheel, a pair of laterally spaced rear wheels, and a seat for a rider, a protective footwell removably mounted to the tricycle and supporting the feet of a rider, and comprising front and rear support links mounting said footwell to said tricycle, wherein said front and rear support links suspend said footwell therebetween with a limited amount of vertical travel, and wherein said footwell has one or more lower wheels normally suspended off the ground in the absence of weight on said footwell, and engaging the ground for rolling therealong in response to a given amount of weight on said footwell. 8. In a tricycle having a longitudinally extending frame supporting a front wheel, a pair of laterally spaced rear wheels, and a seat for a rider, a protective footwell removably mounted to the tricycle and supporting the feet of a rider, wherein said footwell has right and left laterally spaced lower wheels engageable with the ground for enhanced lateral stability. 9. In a tricycle having a longitudinally extending frame supporting a front wheel, a pair of laterally spaced rear wheels, and a seat for a rider, a protective footwell removably mounted to the tricycle and supporting the feet of a rider, wherein said front wheel has a front axle mounted to said frame, and comprising a pair of right and left support links extending forwardly from said footwell on laterally opposite sides of said front wheel and mounted to said front axle and preventing turning of said front wheel about a vertical axis, to provide a steering-lock blocking steering of the tricycle by the rider. 10. The tricycle according to claim 9 wherein each of said right and left front support links has an aft end mounted to said footwell, and has a forward end removably mounted to said front axle, at least one of said ends being pivotally mounted to allow vertical travel of said footwell. 11. The tricycle according to claim 9 wherein each of said right and left front support links has a forward end in the form of a hook hooked on said front axle. 12. The tricycle according to claim 9 wherein said front axle has right and left cranks extending transversely therefrom on laterally opposite sides of said front wheel, said pedals being mounted to said cranks, and wherein said right and left front support links are mounted to said front axle laterally inboard of said right and left cranks, respectively. 13. In a tricycle having a longitudinally extending frame supporting a front wheel, a pair of laterally spaced rear wheels, and a seat for a rider, a protective footwell removably mounted to the tricycle and supporting the feet of a rider, wherein said frame has an aft portion supporting said rear wheels, and comprising a rear link extending from said footwell to said aft frame portion and mounted thereto. 14. The tricycle according to claim 13 wherein said aft frame portion has a first support bar extending laterally thereacross, said footwell has a second support bar extending laterally thereacross, said rear link is mounted to said first and second support bars, said footwell has a longitudinal centerline coincident with said front wheel and defining a longitudinal vertical centerline plane, and wherein said rear link has a lateral extension span transversely crossing said centerline plane and having a laterally widened extension span width stabilizing said footwell against right-left tilting in the event of uneven right-left foot pressure of the rider. 15. The tricycle according to claim 13 wherein said rear link has a first end mounted to said footwell, and has a second end removably mounted to said aft frame portion, at least one of said ends being pivotally mounted to allow
