I also don't like the commercial strategy of Brompton.

But do not like the clones and their manufacturers that, for most of them, stupidly copy everything, even the well known weak points of the Brompton.

A single man like Ben of Kinetics does a much better job with his upgraded Brompton.

For me the Dahon Curl is not a clone, its just inspired by the Brompton with several mods to solve several weak points of the Brompton.

For the Chedech, there are some improvements but it has the drawback of the carbon frame not that good for a folding bike while being much heavier than a T-line.
