Sidi Ergo has pictures and descriptions of the most expensive bicycles ever made, including models plated in gold and encrusted with diamonds. This model, the Koga Kimera, isn't quite so luxurious. But developed by UK bike-maker Koga for Dutch Olympic competitor Theo Bos Koga, it's priced at almost one million dollars. The Kimera is said to have the lowest wind resistance of any bicycle ever made.
