A collapsible frame assembly for a three-wheeled jogging stroller with demountable wheels and a removable cloth-like seat and canopy arrangement. The frame assembly includes a primary fore to aft main structural member with a rear axle assembly having a member of an enlarged diameter tubular construction with couplers at opposite ends thereof for supporting demountable or removable large diameter spoked wheel pneumatic tires with the axles thereof canted so that the wheels are downwardly divergent relative to the ground. A generally U-shaped handle member is affixed to the rear axle tube and dimensioned, configured and positioned for convenient gripping by a user. A T-shaped interconnection mechanism has the leg thereof secured to one end of the main structural member and the crossbar portion thereof receiving the tube of the rear axle assembly therein in perpendicular relation to the main structural member. The interconnection mechanism includes a cam lock device which enables selective relative sliding movement between the rear axle within the cross-bar portion from a first locked position with the handle member generally transverse to a plane formed by the main structural member and the rear axle tube and a second unlocked position with the handle and rear axle assembly pivoted toward the main structural member for positioning the handle proximate the main structural member. The front end of the main structural member has secured thereto a front fork receiving block assembly with a footrest attached on the structural member above the assembly. The block assembly has a vertical sleeve bearing or bushing therethrough for receiving the caster post of the fork assembly for the front wheel. The fork assembly and block assembly are matingly coactingly configured and arranged for enabling selection of front wheel movement to one of two positions - a first locked straight ahead position and a swivel caster position through an angle of about 180 degrees.
