The White , bikes look undergeared ,especially the 16 inch bikes .It is difficult to say for sure though because the number of teeth on the front chainring is not given .To determine the gear inches of any chainring and cog combo divide the number of teeth on a cog into the number of teeth on the front chainring. Here is an example. The front chainring has 52 teeth ,suppose the cog you have shifted to has 26 teeth ,this gives you a 2 to 1 ratio.This means each time the front chainring goes around once the rear wheel will go around twice.If you have a bicycle with a 16 inch wheel /tire combo the gear inches will be nominally 32.I would check out Dahon Bicycles,Brompton bicycles are also well regarded Swift brand folders look good as well .Di blasi is an Italian folder but i consider it undergeared and heavy though you might be able to improve it if you are handy with tools and the bicycle has sufficient clearances to allow such modifications as you see fit to make. This can be expensive though .I would very carefully weigh the cost before going this route. What will you use the bicycle for? Dahon bicycles are better spec'ed than the bikes you provided a link to and are considered among the best bikes in the industry.I own two.Bike Friday bicycles are excellent but are more for touring and racing than commuting and cost many Euro's. By the way Maurizio your english is quite understandable.

i tried the 16 and 20 2weeks ago. Definitevely undergeared.The 16 was too small for me (nearly 6foot) Seems sturdy. suspended front and rear, did seem too soft but could be adjusted. French norms compliant (and they are tough: most Dahon don't meet)
So the seller/builder of these bikes proposed a free upgrade to some 44 teeth i think, way bigger
advantage of a small company, you can talk mods right away . You can try the bike for 3 weeks and return it if not content. Still , you get charged for the shipping
I didnt buy one because of the folded size: need to pack it in a kayak, so had to go for a Brompton for over twice the money. It folds approx the size of Dahon 20s, they have a bag coming with it. At least they did at Paris Cycle Fair.

I like the looks of the Blanc Marine, and the prices are decent. Thank you for the link to their website.
