Bicycle and tire structure

A bicycle, comprising:

• two wheels, at least one of the two wheels comprising:
• a rim;
• and
• a tire structure disposed at the rim and comprising:
• a tire body being ring-shaped and comprising:
• a groove having a groove opening facing toward the rim;
• and
• two beads disposed at two opposite sides of the groove opening, respectively, the two beads configured to engage with the rim, each of the beads comprising a bead seat portion resting on the rim;
• a flexible sealing member having two opposite sides respectively fixed at two edges of an inner wall of the tire body to form an inflating space with the groove, wherein the two edges are near the groove opening, each of the two opposite sides of the flexible sealing member does not connect to each of the bead seat portions, and the flexible sealing member comprises a through hole;
• a nozzle disposed at the flexible sealing member, the nozzle configured to allow a gas to enter the inflating space, the nozzle comprising:
• a base comprising a screw hole, the base disposed at a far side of the flexible sealing member, wherein the far side of the flexible sealing member faces away from the tire body, and the screw hole corresponds to the through hole;
• and
• a valve stem, comprising:
• a fastening end configured to insert into the screw hole;
• and
• an inflating channel configured to allow the gas to flow therethrough;
• and
• an adhesive member disposed at the far side of the flexible sealing member, the adhesive member surrounding and covering a part of the base;
• wherein the base is attached to the flexible sealing member first, then the fastening end of the valve stem is inserted into the screw hole and the through hole to push a burr or an excess material into the inflating space.

A tire structure disposed at a rim, the tire structure comprising:

• a tire body being ring-shaped and comprising:
• a groove having a groove opening facing toward the rim;
• and
• two beads disposed at two opposite sides of the groove opening, respectively, the two beads configured to engage with the rim, each of the beads comprising a bead seat portion resting on the rim;
• a flexible sealing member having two opposite sides respectively fixed at two edges of an inner wall of the tire body to form an inflating space with the groove, wherein the two edges are near the groove opening, each of the two opposite sides of the flexible sealing member does not connect to each of the bead seat portions, and the flexible sealing member comprises a through hole, an inner surface facing toward the tire body, and an outer surface facing away the tire body;
• a nozzle disposed at the flexible sealing member, the nozzle configured to allow a gas to enter the inflating space, the nozzle comprising:
• a base comprising a screw hole, the base disposed at the outer surface of the flexible sealing member, wherein the screw hole corresponds to the through hole;
• a valve stem, comprising:
• a fastening end configured to insert into the screw hole;
• an inflating channel configured to allow the gas to pass therethrough;
• and
• an adhesive member disposed at the outer surface of the flexible sealing member, the adhesive member surrounding and covering a part of the base;
• wherein the base is attached to the flexible sealing member first, then the fastening end of the valve stem is inserted into the screw hole and the through hole to push a burr or an excess material into the inflating space.
