My wife and I rode about 4 miles this afternoon. As Dave says, it rides fine. I am glad I did get the Urbano with the wider tires. It does weigh a bit more but worth the extra stability. 2 will easily fit in the back of a 9-7 tip up and I imagine a slider too. We are headed to northern Michigan later this week to test them out. I am happy with my purchase.
I'm so IMPRESSED you got not one but two folding bikes in baggage area, not one but TWO!!!! I am sure it is a bit of a shoe horn. I wish I had your post when I went through the folding bike hunt for my RV beginning of year. I just went through this. I got a GREEN ZONE bike (20" wheels) which is almost identical to your ZiZZO bikes. They are all made in China or most of components are.
Zizzo, Tern and Dahon are good brands. Some have bought Citizen.
The problem, near impossible to shop and see these in person, most local bike stores don't carry them. If they do it's one brand or larger folding mountain or cruising bikes. You also have to rely on web and on line shopping.
I also found that the folded dimensions given by some brands are optimistic. What is an inch or two or three? For most people it's not a big deal, but for a little plane it makes a difference.
You got good bikes and they fit. Well done. Thanks for the report.
The best source are reviews on folding bikes I found were on on social media (YouTube) or forums. However they don't focus on transport in small plane. I can say there is one bike sure to fit and be decent to ride.
I ended up getting another bike, a BROMPTON (clone). If folds much smaller, lighter. The brand is 3SIXTY. It is made identical to BROMPTON at half the price including shipping. I had to import it from Singapore and SHIPPING cost are nuts, but still a good deal. With an RV7 slider, is a struggle with green zone. A tip up or extended slide for the canopy would make a huge difference loading and unloading.
The 3SIXTY is 16" wheels and 6 speed. The Green zone is 8 speed and 20" rims. The 20" Green zone has a nicer ride, not significant but you can notice. The 3SIXTY is much smaller folded, but unfolded it is identical in seat, handlebar and pedal position to the Green zone.

In the above pictures I show both folded side by side. The Green zone can be made a little more compact when folded by completely removing seat and seat tube (verses just retracting). Also my bike is deluxe with fenders and rack and kickstand. These also come off making it a tad smaller (and pounds lighter) when folded. If you buy a folding bike for your RV don't get the the rack and fenders (or get them and take them off).
They all come with folding pedals, but I have gone to ultra light quick release pedals which saves some weight and space over folding pedals. I am keeping both bikes. The Green zone is perfect for car and camping. It is more beefy and comfortable. The 3SIXTY (Brompton clone) is for airplane. There are other Brompton clones (Litepro, Pikes, Royal). They are identical to Brompton, including parts interchangeable. If you can afford a Brompton, I recommend it. They hold their value. The clones especially the more expensive ones are equivalent in quality, form, fit and function.
