Abstract: Vehicular system, including front wheel having user-interface assembly configured to selectively permit user to operate between limb-operating mode and side-by-side limb cruising mode. In side-by-side limb cruising mode, first and second crank arms are free to float and position by themselves while front wheel is steered to cause vehicular system to turn in such a way that first pedal and second pedal are positioned slightly offset from each other. In side-by-side limb cruising mode, control of vehicular system is improved because rider position is more balanced and an unnatural sensation of steering involving hands and feet becomes neutralized while: user maintains hands coupled to steering assembly and also maintains feet coupled to first pedal and second pedal; steering assembly turns front wheel toward one side; first crank arm and second crank arm freely float and position themselves; and first pedal and second pedal are positioned slightly offset from each other.
