I have a cheap DIY wheelbarrow, in which the wheel was broken, and did not want to have to constantly refill air. I use the truck relatively rare, but need a reliable tool. It helps me this bike because it requires just no air. Compared to the hardware store and some other Internet products, the price is ok. A bargain is not. In addition, was the installation of absolute horror. On my wheelbarrow the wheel fitted with its axis at least not without major design modifications. This has given me God performed thanks someone as friendly turn. Otherwise, the wheel would not have to be mounted. That may at more expensive / better wheelbarrows that may have standard dimensions, have no problem with my 30, - EUR model it was one. So, first check whether the axis can be mounted.
