An apparatus for towing up to two bicycles with another bicycle when the first bicycle is also towing a baby jogging cart or, alternately, a bicycle trailer or trail-a-bike. Particularly useful for exercising a child (or two children) and allowing her to ride a bike until tired, and then towing the child's bike while she rests in the jogging cart, the apparatus comprises a bracket assembly which is removably mounted on the rear wheel support structure of the towing bicycle. The bracket assembly comprises a hitch pin which is removably attached by a flexible connector to a towing arm. The latter is connected to the front of the jogging cart and its undercarriage. Prior to towing the child's or children's bicycle(s), one turns its front wheel approximately 90 degrees. There are provided two locations for mounting the bicycles: the first one being disposed between the rear axle and the back of the jogging cart's seat and the other, which is defined by a wheel carrier, being disposed behind the rear axle of the jogging cart. Straps hold the wheels of the towed bicycles and their handlebars to the jogging cart's axle and handle, respectively. In this position, handlebar stem bearings allow the towed bicycle to easily track behind the jogging cart. Further, when towed, the bicycles lean outwardly during turns; and their rear wheels are free to move over unevenness in the road, thus providing ease of handling for the towing bicyclist.

It is claimed: 1. An apparatus for towing at least one bicycle with a first bicycle, the first bicycle having a rear wheel support structure, comprising: (a) a cart having at least one frame member; (b) a towing means, including a bracket assembly and a towing arm, for pulling the cart behind the first bicycle, the bracket assembly being removably mounted on the rear wheel support structure of the first bicycle, the towing arm being connected to the bracket assembly, an elongated section of the towing arm proximate with the bracket assembly being aligned parallel with the rotational axis of the rear wheel of the first bicycle, the towing arm extending rearwardly from the first bicycle and being fastened to the frame member; and (c) means for removably attaching a second bicycle to the rear of the cart. 2. The apparatus according to claim 1 in which the bracket assembly further comprises two flange plates which are movably coupled together and means, including a bolt and nut for threadedly engaging the bolt, for holding the flange plates in assembled relation when they are clamped around a portion of the rear wheel support structure. 3. The apparatus according to claim 1 which further comprises a flexible connector for connecting the towing arm to the bracket assembly, the flexible connector being disposed downwardly of the lowest point on the rear wheel support structure. 4. The apparatus according to claim 1, which further comprises means, including a wheel carrier bracket attached to the cart, for towing a third bicycle, the bracket holding the front wheel of the third bicycle during towing. 5. An apparatus for towing at least one bicycle with a first bicycle, the first bicycle having a rear wheel support structure, comprising: (a) a cart having at least one frame member, a rear axle, and a handle; (b) a towing means, including a bracket assembly and a towing arm, for pulling the cart behind the first bicycle, the bracket assembly being removably mounted on the rear wheel support structure of the first bicycle, the towing arm being connected to the bracket assembly, the towing arm extending rearwardly from the first bicycle and being fastened to the frame member of the cart; and (c) means, including at least one first flexible strap for holding the front wheel of a second bicycle near the rear axle of the cart, at least one second flexible strap for attaching the handlebar of the second bicycle to the handle of the cart, and a wheel carrier which is supported by the rear axle of the cart, for towing a second bicycle with its front wheel held in a position in which it is turned at an angle of approximately 90 degrees, the wheel carrier holding the front wheel of the second bicycle when it is so turned. 6. An apparatus for towing at least one bicycle with a first bicycle, the first bicycle having a rear wheel support structure, comprising: (a) a cart having a handle, a rear axle, and front wheel support forks; the cart having its front wheel removed; (b) a towing means, including a bracket assembly and a towing arm, for pulling the cart behind the first bicycle, the bracket assembly being removably mounted on the rear wheel support structure of the first bicycle, the towing arm being connected to the bracket assembly, the towing arm extending rearwardly from the first bicycle and being fastened to the front wheel support forks of the cart; and (c) means, including the handle having an elongated hand grip and a rigid frame, at least one first flexible strap for holding the front wheel of a second bicycle near the rear axle and at least one second flexible strap for attaching the handlebar of the second bicycle to the handle of the cart, for towing the second bicycle with its front wheel held in a position in which it is turned at an angle of approximately 90 degrees; the rigid frame terminating upwardly in spaced apart first and second frame members, distal ends of the hand grip being attached to the frame members in such a way that, in use, the hand grip and frame members define an inverted, generally U-shaped structure for receiving the handlebar of the second bicycle when the handlebar is attached to the handle with the second flexible strap, one end of the hand grip being removably attached to the first frame member, so that said removably attached end can be temporarily separated from the first frame member, thereby forming an opening through which the handlebar of the second bicycle can be passed prior to use. 7. The apparatus according to claim 6 wherein the hand grip is further characterized as being sufficiently flexible to facilitate cornering of the second bicycle. 8. An apparatus for towing second and third bicycles with a first bicycle, comprising: (a) a cart having a rear axle: (b) means for pulling the cart behind the first bicycle; (c) means for towing the second bicycle with its front wheel held in a position in which it is turned at an angle of approximately 90 degrees and held near the rear axle of the cart; and (d) means, including a wheel carrier bracket attached to the cart, for towing the third bicycle, the wheel carrier bracket holding the front wheel of the third bicycle in such a way that, during towing, its front wheel is disposed generally at an acute angle to the longitudinal centerline of its frame and its rear wheel is free to ride on the road behind the cart.
