I'm amused by those riding on one single-gear.
Here in Chino Roces, Makati CBD, a street near my office building... I often spot a group of fixed gear cyclists. Their rigs are very eye-catching... although from my point-of-view its very rare to see fixed gear bikes especially groups here in the metro. The most bikes I often see are mountain bikes, road bikes and folders... but rarely do I see a fixie or two.
Maybe... just maybe, fixed gear will someday bloom here in the Philippines, just like the scenes in Malaysia, Hongkong and Singapore.
If you're a fixie and lookin for buddies, you might want to check Commence Manila.
But if your a single-speeder, you might want to check the local mountainbiking scene.
