Patent ID: 8678520

Claim:
A foldable wheel comprising: a plurality of extendable spokes, wherein each spoke consists of multiple spoke portions which can be nested with each other for expansion or contraction of spoke length, one end of the spoke is connected directly or indirectly to a wheel rim, the other end of the spoke is directly or indirectly connected to a wheel hub; the wheel rim which can be segmented and detached from the spokes for portability and assembled into a whole rim and is connected directly or indirectly with the spokes in extended position for use; the wheel hub which can be connected directly or indirectly with one end of the spokes to keep the spokes in place; by segmenting the wheel rim, detaching the spokes from the wheel rim, and allowing the spoke portions to be nested, a size of the wheel can be reduced for portability; when the nested spokes are extended, the spokes can recover their lengths allowing the spokes to be connected with the wheel hub and the assembled wheel rim for usage; and wherein the wheel hub is further composed of multiple segments capable of nesting with each other for contraction or extension, wherein the nested extendable spokes are paired and connected to each other at the rim side of their ends, the remaining two ends of the spoke pairs are connected directly or indirectly to the two ends of the extendable hub allowing the wheel hub and the spokes to be folded into portable form and unfolded into riding form by adjusting the length of the spokes and the wheel hub.
