1. A scooter device propelled by side to side movement of a user, comprising: at least a first forward located wheel;at least a second and a third rearward located wheel, the second and third rearward located wheels mounted in a biased direction arrangement;a frame structure through which the first wheel is coupled to the second and third wheels, the frame structure including a rear support member extending substantially continuously between the second and third wheels; anda shaped human support platform coupled to and extending above the rear support member, the human support platform being positioned above a central portion of the rear support member; anda steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that turning of the steering mechanism achieves a turning of the first wheel;wherein the rear support member includes a second wheel support section that extends toward the second wheel and a third wheel support section that extends toward the third wheel, each of the second wheel support section and the third wheel support section having a lateral dimension that is greater than its longitudinal dimension. 2. The scooter device of claim 1, wherein the rear support member is positioned substantially above the second and third wheels. 3. The scooter device of claim 1, wherein the steering mechanism and first wheel are arranged such that for steering purposes there is a singular front wheel which is the first wheel. 4. The scooter device of claim 3, wherein the frame structure includes a principal longitudinal frame member that extends rearward of the steering mechanism and, during use, is fixedly and non-movably coupled to the rear support member. 5. The scooter device of claim 1, wherein the frame structure includes a principal longitudinal frame member and the rear support member is arranged substantially perpendicularly to the longitudinal axis of the principal longitudinal frame member. 6. The scooter device of claim 1, wherein the front wheel is larger than the second or third wheel. 7. The scooter device of claim 1, further including a brake. 8. The scooter device of claim 1, wherein the biased direction arrangement includes at least one of a forward tilted caster arrangement and a spring biased caster arrangement. 9. A scooter device propelled by side to side movement of user, comprising: at least a first forward located wheel;at least a second and a third rearward located wheel, the second and third rearward located wheels mounted in a biased direction arrangement;a frame structure through which the first wheel is coupled to the second and third wheels, the frame structure including a principal longitudinal frame member and a principal rear support member that extends substantially outwardly from the frame member to the second and third wheels;a steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that a turning of the steering mechanism achieves a turning of the first wheel; andwherein the rear support member includes a second wheel support section that extends from the frame member toward the second wheel and a third wheel support section that extends from the frame member toward the third wheel, each of the second wheel support section and the third wheel support section having a lateral dimension that is greater than its longitudinal dimension;wherein the steering mechanism and first wheel are arranged such that for steering purposes there is a singular front wheel which is the first wheel; andwherein, during use, the rear support member is fixedly coupled to the longitudinal frame member such that the rear support member does not move relative to the longitudinal frame member. 10. The device of claim 9, further comprising a shaped user support platform provided with the rear support member, the platform positioned at least in part above a central portion of the rear support member. 11. The device of claim 10, wherein the rear support member is provided substantially above the second and third wheels and the platform extends above the rear support member. 12. The scooter device of claim 9, wherein the rear support member is arranged substantially perpendicularly to the longitudinal axis of the principal longitudinal frame member. 13. The scooter device of claim 9, wherein the front wheel is larger than the second or third wheel. 14. The scooter device of claim 9, wherein the biased direction arrangement includes at least one of a forward tilted caster arrangement and a spring biased caster arrangement. 15. The scooter device of claim 9, wherein the rear support member is arranged substantially perpendicularly to the longitudinal axis of the principal longitudinal frame member. 16. A scooter device propelled by side to side movement of user, comprising: at least a first forward located wheel;at least a second and a third rearward located wheel, the second and third rearward located wheels mounted in a biased direction arrangement;a frame structure through which the first wheel is coupled to the second and third wheels, the frame structure including a principal longitudinal frame member and a principal rear support member that extends substantially outwardly from the frame member to the second and third wheels, wherein, during use, the rear support member is non-movably coupled to the frame member;a human support platform provided with and extending above the rear support member, the human support platform being positioned, at least in part, equidistant from the second and third wheels; anda steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that a turning of the steering mechanism achieves a turning of the first wheel;wherein the biased direction wheel arrangements include at least one of: tilted caster wheel arrangement, andspring biased caster wheel arrangement. 17. The device of claim 16, wherein the rear support member has a substantially linear or curvilinear shape. 18. The device of claim 17, wherein the steering mechanism and first wheel are arranged such that for steering purposes there is a singular front wheel which is the first wheel. 19. The scooter device of claim 16, wherein the first wheel is larger than the second or third wheel.
