The more I think about transportation, the more I realize that a bicycle is like a magician's broomstick.

The Potter is a new tire that is perfect for the magical tool that allows you to ride lightly through the city in your daily life, seeking new encounters and discoveries, or packing a special bag for holidays and taking you to cities you have never visited or adventures you have never experienced beforE

The Potter is a 20-inch tire that was commercialized in response to the requests of many small-diameter vehicle riders for a tire that combines performance and good looks. There are two 20-inch standards, WO (451) and HE (406), and the Potter is available in two types to accommodate both standards, making it possible to fit many of the 20-inch small-diameter vehicles on the market.

The tire boasts excellent puncture resistance against all types of punctures, including side cuts, as well as normal through-hole punctures.

The tires are manufactured by Panaracer at its own factory in Japan to ensure safety and stability for your toes.
