I think you're right about tandems. Down in New Orleans, we had one at our last alleycat and I have some friends who just welded one up instead of making a tall bike. Tandems could definitely become popular. Plus, as the tandem riders at our last alleycat demonstrated, they can do twice as many asinine tricks as a single rider.

To the OP, why'd you buy the recumbent? It would seem to have very different utility from a fixed. I'm a big fan of recumbents but I just can't see anyone weaving through traffic, locking their bike in front of shady bars and such. Also, what's with the strange padding on the seat? Is that stock? Again, great bike. Someday I'll ride a Lightning F-40 and I'll be so damn fast I wont care about being a Fred.
