I could be wrong but I think that irclean is a forum member, not a brand of bicycles.

I rode a Pug late last fall, just on turf and asphalt which of course is not the best way to get a feel for its unique capabilities. Amazingly though, it just disappears under you when you ride it on those surfaces. You don't really feel that there is anything odd about the bike, it handles well and feels like any other nice bike. I presume that it becomes exceptional in its element but it certainly does not feel awkward, sluggish, or anything of the sort on normal riding surfaces as you might fear. People who own one seem quite taken with them. The first time I saw one was in the LBS where its owner had brought it in, for "show and tell" I guess. He claims it puts a big grin on his face every time he rides it, even around the block. It would be hard to question his assessment since he was grinning ear to ear the whole time.
