Originally it seems to be sold as a bicycle, but the size was sought and the price was affordable so buy it. Naturally, although I do not agree with the bike's career properly, I bought a suitable metal fitting and bolt nut from the home center and wore it (it was about 600 yen). As a result, there is no problem at all. It has a width of 45 centimeters, and it's easy to put in a backpack containing a personal computer day and day, so I fixed it tightly, so there is no problem. Depending on the type of motorcycle, there is a difference whether or not it can be installed properly, but my bike is Honda's gyro X. Very pleasant and satisfied.
