I stand corrected.

I assumed that "sealed" in the Dahon hub specs meant "not loose balls". Reviewing the Dahon specs, "cartridge" is the term they use for "not loose balls". My 2008 Speed P8 has "cartridge" bearings. I repacked the front hub bearings on a 2005 Boardwalk D7 last year. That hub was like the hub on your Speed D7. Now I know it was a "sealed" hub.
