Abstract
A quick assembly bicycle inner tube comprising a cylindrical hollow body strip with two distal ends, a valve, and end covers that are formed of round cup shaped bodies and end caps. The air valve is installed on the inner tube. The inner tube has two end covers (head covers), each of which is installed on a distal end of the tube. The end covers are made of the same material as the hollow body. Each end of the tube end covers has a closed end cap. The quick assembly bicycle inner tube and the method of installing the inner tube, eliminates the need for tools to disassemble the wheel set by allowing the user to manually remove and replace the inner tube without removing the wheel set from the bicycle. The inner tube is further easily folded into a flat shape to facilitate easy portability.

A quick assembly bicycle inner tube comprising:
- a cylindrical hollow main body having disjoined distal ends;
- a valve installed on the inner tube through the hollow main body;
- a pair of cylindrical end covers, each cover installed on each distal end of the tube, wherein the pair of cylindrical end covers are formed of the same material as the hollow main body;
- and
- a closed end cap on each end cover at each distal end.
A method of installing a bicycle inner tube for a bicycle, the inner tube comprising a cylindrical hollow main body having disjoined distal ends;
- a valve installed on the inner tube through the hollow main body;
- a pair of cylindrical end covers, each end cover installed on each distal end of the tube, wherein the end covers are formed of the same material as the hollow main body;
- and a closed end cap on each end cover at each distal end, the method comprising:
- prying a bicycle tire away from a wheel rim of the bicycle to form an opening, while the wheel is engaged in a fork or a dropout frame of the bicycle;
- inserting one distal end of the inner tube in the opening;
- inserting the valve through a valve hole on the wheel rim;
- guiding the inner tube through the opening while rotating the wheel;
- and
- inflating the inner tube until the distal ends come into close contact forming a ring.
