We recently purchased a used RF bike for our smallest grandson. The bikes are made in China but are very well made and heavy duty for their size. They would last a lifetime except for one very bad design flaw that we quickly became aware of. The chain kept coming off and i see why. The crank dosent have real bearings. It has plastic bushing things that wear out making the bike useless. I see no way to repair it without getting the parts from RF and costing more than the bike is worth. Moral of the story....STAY AWAY from the RF bicycle. I guess they figure that if it tears up you will go buy another to replace it. The name alone sells them.
