The pin is too short. Hanging the pin on the drum and turning it with the force, I could not use it because the pin pulled out with a slack. Since there is no choice, it fixed in 10 holes × 2 holes to the stick of the stilt through a wire in the hole of the drum, and it was able to be removed when turning with the principle of lever.
I call it universal but can not it be used for bicycles? I think that it is better to change the product name to a holder for a motorcycle if it can not be used for a bicycle.
