Although it is a simple structure, it is difficult to make home-made, it is convenient to fix the bicycle from which the tire was removed. (If the tire is attached, you can fix the tire by tying the down tube.) However, I think the price is high for easy making.
If you have a tire you should tie the tire and the frame with a band, but if the tire is not attached this holder will come in handy. Work efficiency improves by fixing the steering wheel. Because it is a simple mechanism I think that the price will go down a little more.
