My A-bike copy is now come up on it's 400 km mark. The one small problem that has set in is a small crack on the rear frame tube. I read about this happening so I was not too surprised by it. I placed a hose clamp on te frame to tighten up this section. Other the the normal amount of wear on the rear drive wheel and front wheel, it is holding up good. It is feeling solid still.
My hope of having 500 km by Nov. could be reached. It just depends on the weather and what other bikes are being used as needed.
