Does the number of spokes on a wheel determine its strength?
A wheel's strength comes from its material and manufacturing, not the number of spokes.
No. The strength and durability of a wheel depend mostly on the material it is made from and the manufacturing process, not the number of spokes.
Spokes are mainly a design choice, and while they can affect weight and style, they do not determine how strong the wheel is. Whether a wheel has a few spokes or many, it can be just as strong if it is built from quality materials and manufactured properly.
