Confirm the tyre sizeCount the number of spokes
The length of the spokes is determined by the rim, hub and braiding method (the length may vary). If the spokes are not suitable for the original spokes, they can therefore be adjusted by a braided process. If not, the spokes can only be purchased again. The knife rim actually refers to a type of reinforced rim that is stronger than the ordinary rim. The so-called knife ring is only a common name of people, as the outer surface of the ring (against the hub side) is relatively high like a knife, so it is referred to as a knife edge.

1. Manual measurement, please allow 1-2 cm error, thank you!2. The image may not reflect the actual colour of the project due to the differences between different displays.3. Look at the tyre size first and then count the number of spokes.4. The rims are thickened rims. Bicycles and electric bicycles are common.
