Hello.  I am new to the forum and I haven't found any other info on this.  I commented in another thread a little but thought maybe I should get the question out to the masses. 

I have a son that is 4'8" tall.  12 yrs old.  Little dude, light weight.  He likes to ride and wants to join the jr high club next year.  So I am trying to build as light of a bike as reasonably possible without breaking the bank. I am loving the world of chinese carbon. 

A traditional size small (15 / 15.5") is too big for him still. 560ish mm TT is still too long.  I have come across some chiners that make a 14" 26ers.  14" is small enough to be functional yet will still allow some growth.  Then his younger bro can inherit it. 

I came across a "brand" that does a 29er in a 14".  This strikes me as a little weird and I would like to know people's thoughts on the geometry of such a small frame with 29er wheels.  I absolutely love the possibility but am curious if this raises any red flags for anyone. Also, it seems like every one of these "brands" have the same pictures and graphs that I want to be sure this isn't just a typo (I need to contact them directly).

Finally for all you chiner veterans, with a hundred bikes that seem to come from the same place, same photos, but with different names, how do I choose the best one?

Thanks for any suggestions.
