A bicycle towing device which is positioned between a tow bicycle, such as an adult bicycle, and a towed bicycle, such as a child's bicycle, and enables the towed bicycle to function as a one wheeled bicycle trailed behind the tow bicycle. The bicycle towing device in accordance with the present invention enables the towing of an intact and ridable towed bicycle behind the tow bicycle by lifting the front wheel of the towed bicycle off the ground and, if desired, the towed bicycle can be pedaled while it is being towed by the tow bicycle. When not in use, the bicycle towing device in accordance with the present invention is capable of being collapsed and stored on the tow bicycle. When it is desired to operate the towed bicycle in a one wheeled bicycle trailed mode, the bicycle towing device is capable of being removed from its stored position on the tow bicycle, extended and quickly and easily attached to the towed bicycle such that the towed bicycle can be ridden as a one wheeled bicycle trailer behind the tow bicycle.

What is claimed is: 1. A bicycle towing device for attachment between a tow bicycle having a seat support area, a rear wheel, and a rear wheel axle and a towed bicycle having a front wheel, a handlebar, a head tube and a front wheel fork, the device comprising: a longitudinally extending tow bar ha
What is claimed is: 1. A bicycle towing device for attachment between a tow bicycle having a seat support area, a rear wheel, and a rear wheel axle and a towed bicycle having a front wheel, a handlebar, a head tube and a front wheel fork, the device comprising: a longitudinally extending tow bar having a first tow bar end and a second tow bar end, wherein the first tow bar end is attached to the seat support area of the tow bicycle and the second tow bar end is removably attachable to the head tube of the towed bicycle; wherein the tow bar is telescopic having an extended towing position and a retracted storable position; wherein the front wheel of the towed bicycle remains attached to the front wheel fork and is elevated when the tow bar is attached to the towed bicycle; wherein the second tow bar end is pivotally moveable about the first tow bar end attached to the seat support area to a storage position adjacent the rear wheel axle on the tow bicycle when the second tow bar end is removed from the towed bicycle such that the tow bar is offset from a radial plane through the rear wheel of the tow bicycle. 2. The bicycle towing device of claim 1, further comprising a storage clip assembly attached near the rear wheel axle of the tow bicycle to retain the second tow bar end in the storage position on the tow bicycle. 3. The bicycle towing device of claim 1, further comprising a handlebar locking bar having a first end and a second end, wherein the first locking bar end is pivotally attached to the tow bar between the first tow bar end and the second tow bar end and the second locking bar end is removably attached to at least one of the handlebar, the front wheel fork, and the front wheel of the towed bicycle to preclude rotational movement of the handlebar of the towed bicycle. 4. The bicycle towing device of claim 3, wherein the locking bar is pivotally moveable about the first locking bar end to a storage position adjacent the tow bar. 5. The bicycle towing device of claim 1 further comprising a pivot block positioned intermediate the tow bar and the tow bicycle to permit relative rotation between the tow bicycle and the towed bicycle about a generally vertical axis for pivoting during cornering and about a generally horizontal axis for pivoting during elevational changes between the tow bicycle and the towed bicycle. 6. The bicycle towing device in accordance with claim 5, wherein the pivot block is attached to the seat support of the tow bicycle by a seat post clamp such that the pivot block is adjustable along the longitudinal axis of the seat post. 7. The bicycle towing device of claim 1, wherein the tow bar is generally longitudinally curved. 8. The bicycle towing device of claim 1, wherein the second tow bar end comprises a coupler which corresponds to and engages with a receiver mounted on the towed bicycle to removably attach the tow bar to the towed bicycle. 9. A bicycle towing device for attachment between a tow bicycle having a seat support area and a rear wheel axle and a towed bicycle having a front wheel, a handlebar, a head tube and a front wheel fork, the device comprising: a longitudinally extending tow bar having a first tow bar end and a second tow bar end, wherein the first tow bar end is attached to the seat support area of the tow bicycle and the second tow bar end is removably attachable to the head tube of the towed bicycle; wherein the tow bar is telescopic having an extended towing position and a retracted storable position; wherein the relative angle between the tow bar and the towed bicycle is adjustably positioned to elevate the front wheel of the towed bicycle wherein the front wheel remains attached to the front fork of the towed bicycle; a handlebar locking bar having a first end and a second end, wherein the first locking bar end is pivotally attached to the tow bar between the first tow bar end and the second tow bar end and the second locking bar end is removably attached to at least one of the handlebar, the front wheel fork, and the front wheel of the towed bicycle to preclude rotational movement of the handlebars of the towed bicycle wherein the second tow bar end is pivotally moveable about the first tow bar end attached to the seat support area to a storage position adjacent the rear wheel axle on the tow bicycle when the second tow bar end is removed from the towed bicycle. 10. The bicycle towing device of claim 9, further comprising a storage clip assembly attached near the rear wheel axle of the tow bicycle to retain the second tow bar end in the storage position on the tow bicycle. 11. The bicycle towing device of claim 9, wherein the locking bar is pivotally moveable about the first locking bar end to a storage position adjacent the tow bar. 12. The bicycle towing device of claim 9, wherein the attachment of the first locking bar end to the tow bar, the attachment of tow bar to the towed bicycle, and the attachment of the second locking bar end to one of the handlebar, the front wheel fork, and the front wheel, forms a triangle in a generally vertical plane. 13. The bicycle towing device of claim 9 further comprising a pivot block positioned intermediate the tow bar and the tow bicycle to permit relative rotation between the tow bicycle and the towed bicycle about a generally vertical axis for pivoting during cornering and about a generally horizontal axis for pivoting during elevational changes between the tow bicycle and the towed bicycle. 14. The bicycle towing device in accordance with claim 13, wherein the pivot block is attached to the seat support of the tow bicycle by a seat post clamp such that the pivot block is adjustable along the longitudinal axis of the seat post. 15. The bicycle towing device of claim 9, wherein the tow bar is generally longitudinally curved. 16. The bicycle towing device of claim 9, wherein the tow bar is longitudinally adjustable to permit adjustment of the distance between the tow bicycle and the towed bicycle when the bicycle towing device is attached to the tow bicycle and to the towed bicycle.
