20” front wheels are often found on bicycles, trailers, collapsible bicycles, recumbent bicycles, and children’s bicycles. From this size, these tires are used for a wide variety of things, not only in the area of bicycles. The use of a hub dynamo even makes with this wheel size since smaller bikes often do not get up to the required speeds needed for bigger wheels. Disk brakes can also be easily built onto a wheel of this size. We, at Taylor Wheels, offer a large selection of 20” wheels. You will hardly be able to believe that there are 7 different diameters. In our shop, you will find the standard size or ETRTO 406 mm. This is the standard size in this area.
