An apparatus is provided for bicycles to make them more utilitarian and functional. The attachment is easily attached, and potentially attached without damage or significant modification to the bicycle. The apparatus includes a frame member attached to the bottom bracket portion of the existing bicycle, and a gimbal attached to the fork of the existing bicycle in place of the original front tire. The apparatus is steerable using the handle bars and fork on the existing bicycle frame, and is configured for stability when cornering. The apparatus includes a cargo carrier located in front of the cycler where it is easy to see, while maintaining a stable center of gravity and also an ability to lean into corners for cornering stability. Variations include one or two front wheels, and one or two steering drive links. Also, the apparatus is a flexible design providing multiple potential utilitarian uses.

1. An apparatus comprising: a primary frame, a rear wheel, and a steering mechanism including handle bars connected to front forks and journaled to the primary frame for turning the front forks;a pivot adapter attached to the primary frame;a subframe engaging the pivot adapter for rotation and extending side-to-side and including an axle support;a front axle assembly on the subframe, the front axle assembly including a king pin rotatably engaging the associated axle support and including a stub axle for supporting a front wheel and including a steering control arm;an assembly on the subframe, the assembly including a front-fork-engaging member and a steering driver arm; anda steering mechanism including a steering bar operably connected between the steering control arms and the assembly so that upon rotation of the handle bars and front forks the steering driver arm moves the steering control arms to steer the front wheel; wherein the assembly includes a vertical mount attached to the subframe, an assembly vertical axis member rotatably mounted on the vertical mount, a slider slidably and rotatably mounted to an assembly horizontal axis member extending from the vertical mount, the slider including arms attached to the front forks. 2. The cycle apparatus defined in 1, wherein the assembly includes a stabilizer yoke attached to the slider that produces controlled rotation of the slider. 3. A cycle apparatus comprising: a primary frame, a rear wheel on the primary frame, and steerable handle bars journaled to the primary frame and adapted for steering;a subframe operably connected to the primary frame so that the primary frame can tilt relative to the subframe, the subframe having at least one steerable front wheel; anda steering assembly attached to the primary frame and to the subframe including a steering control connecting the at least one steerable front wheel to the steerable handle bars, and having a yoke, a yoke stabilizer, a yoke stabilization bolt, and a fork slider connected to the yoke;whereby a rider can motivate the primary frame and tilt the primary frame when turning corners and simultaneously steer the at least one front wheel without tilting the subframe.
