Vivinavi

monocycle

The pink one is 18" and the black one is 20".
The pedals turn relatively smoothly. The tires are deflated, but there is a possibility of a flat tire. The black one has a torn saddle, rust on both, etc. The pink one is made in Japan, and the position of the inflator seems to be special, so I couldn't inflate it with my own inflator, so I took it to a bicycle shop to have it inflated.

Since I no longer use it, I hope someone who can maintain and use it will give it to me.
