Should be able to get under 25 with a converted mountain bike without much effort. Those LocoCycles look like they use some pretty cheap parts and the frames just look heavy. If you wanted light you could dump the deep V style wheels and the extra wide top tubes. Seem like they are going for looks rather than any sort of performance or weight savings but if you're enjoying them, that's all that matters.

Revising the Rockhopper I mentioned back at the top of this thread with a Eno eccentric hub laced to a Velocity Aeroheat and making a sort of townie/speedster like the ridiculously priced but kinda cool Speedvagon Urban Racer
