It can realize functions such as human riding, electric power, or electric assist (i.e., pedal drive, electric power, and pedal drive). After a long period of riding, the outer surface of the tire will inevitably produce a certain amount of wear and tear, and the tire needs to be replaced in a timely manner to ensure the safety of the rider. However, the existing technology has the following shortcomings when used:

[0033] Example:

[0034] like Figure 1-7As shown, the present embodiment proposes an easily replaceable anti-skid tire for an electric-assisted bicycle, comprising a wheel hub 1, a first hub edge 2 and a second hub edge 3 being provided on both sides of the wheel hub 1, an annular tire groove 4 being provided on the wheel hub 1, an inner tube 5 being provided in the annular tire groove 4, an outer tire 6 being provided on the outer cover of the inner tube 5, the outer tire 6 being made of a silicone rubber material, which has relatively outstanding anti-skid performance on wet and slippery roads and can effectively increase the friction between the tire and the ground, the outer tire 6 being located between the first hub edge 2 and the second hub edge 3, an air valve hole 7 being provided on the wheel hub 1, an air nozzle 8 being fixedly connected to the inner tube 5 and being deflated by the air nozzle 8, and four circumferentially arranged positioning holes being provided on the first hub edge 2. Hole 9, four circumferentially arranged positioning pins 10 are fixedly connected to the wheel hub 1, and the positioning pins 10 are located in the positioning hole 9. Four circumferentially arranged first threaded holes 11 are provided on the first wheel hub edge 2, and four circumferentially arranged second threaded holes 12 are provided on the wheel hub 1. The first threaded holes 11 and the second threaded holes 12 are commonly threadedly connected with fixing bolts 13. The four fixing bolts 13 are screwed by tools such as hand drills. When the fixing bolts 13 are disengaged from the second threaded holes 12, the first wheel hub edge 2 is removed. A gasket 14 is sleeved on the fixing bolts 13. Pull the inner tube 5 to disengage the air nozzle 8 from the air nozzle hole 7, then take the inner tube 5 out of the annular tire groove 4, and the outer tube 6 is also removed.

[0035] like Figure 1 As shown, a first mounting block 15 is provided at the center of the first hub edge 2 , and a plurality of first spokes 16 are fixedly connected between the first mounting block 15 and the first hub edge 2 .

[0036] like Figure 3 As shown, a hub 17 is provided at the center of the wheel hub 1, and a second spoke 18 is fixedly connected between the hub 17 and the wheel hub 1, and the number of the second spokes 18 is several. The spoke structure can reduce the overall weight of the wheel while ensuring strength, which is beneficial to improving riding efficiency, evenly dispersing stress from all directions, and avoiding local force concentration that causes wheel deformation or damage.

[0037] like Figure 2 As shown, a second mounting block 19 is provided at the center of the second hub edge 3 , and a plurality of third spokes 20 are fixedly connected between the second mounting block 19 and the second hub edge 3 .

[0038] like Figure 1 and Figure 4 As shown, a protective sleeve 21 is provided on the threaded sleeve of the air nozzle 8 to prevent water and dust from entering the air nozzle 8.

[0039] like Figure 1 and Figure 2 As shown, the second hub edge 3 is fixedly connected to the hub 1 .

[0040] like Figure 1 and Figure 6 As shown, the washer 14 fits against the first hub edge 2, helping to prevent the fixing bolts 13 from loosening under vibration or dynamic loads, thereby improving the stability and reliability of the connection.

[0041] Specifically, when the electric-assisted bicycle is used with an easy-to-replace anti-skid tire: the staff rotates the protective cover 21 to remove it from the air nozzle 8, deflates the inner tube 5 through the air nozzle 8, and screws the four fixing bolts 13 with a hand drill or other tool. After the fixing bolts 13 are disengaged from the second threaded hole 12, the first hub edge 2 is removed, the inner tube 5 is pulled to disengage the air nozzle 8 from the air nozzle hole 7, and the inner tube 5 is taken out of the annular tire groove 4, and the outer tire 6 is also taken out. The inner tube 5 is taken out of the outer tire 6, and then the inner tube 5 is placed in the new outer tire 6. A small amount of gas is first filled into the inner tube 5 by using an air pump and the air nozzle 8, and then the inner tube 5 is placed in the annular tire groove 4, so that the air nozzle 8 is located in the air nozzle hole 7, and the first hub edge 2 is placed on the wheel On the hub 1, four locating pins 10 are respectively inserted into the four locating holes 9 to preliminarily position the first hub edge 2, and then the four fixing bolts 13 are screwed by tools such as a hand drill, so that the four fixing bolts 13 are respectively threaded into the four second threaded holes 12, so that the four gaskets 14 are tightly fitted with the first hub edge 2, and the first hub edge 2 is fixed. The outer tire 6 is placed between the first hub edge 2 and the second hub edge 3, and the replacement of the outer tire 6 is completed. The operation is convenient. When replacing, the staff does not need to pry the outer tire 6 with a tire lever, which reduces the labor intensity of the staff. The four gaskets 14 are tightly fitted with the first hub edge 2, which helps prevent the fixing bolts 13 from loosening under vibration or dynamic loads, thereby improving the stability and reliability of the connection.
