Cheap german bikes and online shopping
I've ordered small and large parts from bike-discount.de. 100% satisfied and cheapest price for those specific parts at that time after comparing with at least 6 other known e-shops.

Regarding cheap german bikes, I don't know about Radon (they don't seem to be well known to the rest of the EU), but I own a canyon torque for the last 3 years and a pal of mine owns a yt noton (both companies well known around the globe). Both are cheap german bikes with high end specs at lowest price possible. We are both 100% satisfied with the bikes, the build and 90% satisfied with after market support.
