I had no idea one can do that. But I bet the shops around me don't have the tools to thread fork steerer.
I guess the 2 bike shops I use are bit better equipped.

One final point is the fork dropout spacing. Doesn't the BMX use 100mm spacing? And Dahon use 74 or something. If so, you would need to make sure to get the BMX wheel also.
And it might interfere with the folding!
The other folding bike owner above managed to get a Dahon Ciao that had been fitted with a fork that fit. I'm sure a bike shop can provide this assistance.
And yes, the spacing is 100mm. If the slimmest fold is required it's unacceptable. Otherwise, it'll work just fine,...a new bmx wheel or so later. I doubt the op will be upset getting a wider old for the front wheel, since they already have those knobbies on there.
All and all, a bmx fork will work.
