There are many different manner to use a folding bike that have (very) different requirements, some examples:
- folding bike to travel by air, train...
- folding bike for multimodal commuting bike+subway+bus...
- folding bike to be transported in a small car like the Miata mentioned by several forum members, folding bike to be transported in a small private airplane, a boat.
- folding bike for short distances
- folding bike for big distances
- only on paved roads or on trails
- folding bike that must be carried by hand over relatively long distances

Such a best value for money is just meaningless because it doesn't take into account the use of the folding bike.

BTW., such consumer test reports exists also elsewhere than in the US.
