The downside will be the fold size, but at least the folding is easy and rather fast.
I'd take a look at the 24" and 26" Tern/Dahon options as well.
What the larger wheeled bikes offer over smaller wheeled ones will be better rolling over poorer terrain, usually some wider tire options and perhaps easier sourcing of wheels/tires (depending on where you live) .
There is ultimately a speed difference between smaller vs larger wheels too.
Max gearing (for larger wheels ) and rotational/frictional losses (for smaller wheels) all add up if riding with folks on road bikes is part of the riding that you do.
Beautiful folding bike. Do you have more pictures and up close. You did a great job with it. Was it a stock bike or did you build up a frame. I'd take this bike over a Helix any day.
