I can see where Abu Mahendra is coming from.
(Being in SEA and not in the US)
There are loads of folding/mini velo bike options here in SEA (often at good prices).
Someone based here gets to try/see lots of the bikes mentioned.

I too seem to see that there is a view here that the BF (and often Brompton) being the only best options. (implying most other stuff being 'cheap copies', inferior workmanship, etc)
Is it really true or is it because of the realities of availability, price (imported vs local), perception of quality, vocal user base?
Even the general size/weight/height of the user base play a part in this perception.


Take a Tyrell FX for instance.
Its a really nice bike, speedy, configurable, etc.
Sadly, most of the available English info on them are limited to distributor and 'self love' selfies type material.
Other info being in Chinese (from HK, Taiwan, China), and Japanese (where the bike originates).

The BF on the other hand, being more readily available in the US (which folks tend to be more vocal and willing to create good content), will turn out lots of good info/material on real world usage upon a google search.
