The folders are great for RVers. It's easy to put them in the back of the tow vehicle if you have a travel trailer and if you have a motorhome (Class A or C) that you tow a car behind (called a Toad in RV speak) you can put the folding bike in the back of the Toad.
I bought a Blix Vika+ back in 2019 and found it fun to ride, very high build quality and a perfect first eBike. We are RVers so it worked perfectly to put in the Toad. The Blix folding eBike costs a full 70% more than cheaper folding bikes like the Lectric eBike but even at $1700 has a waiting list for deliveries.
My Blix was so much fun that I wanted more of that and bought a Dillenger Premium Off-Road kit to turn a Specialized Crosstrail hybrid bike in my garage into an eBike and that's been a great success.
PS. I'm in the process of selling the Folding bike because my new bike has really replaced it.
