Sure, Brompton is the brand. There’s lots of videos and stuff out there. This is the company website: https://www.brompton.com/
Not my pic, but this is how they look in “shopping cart mode”: https://i.redd.it/0ijx1ewfxip21.jpg
The bikes have a special mounting bracket for the bag, and it’s designed so the bag can just stay on the whole time, even when the bike unfolds again.
Meanwhile in the Netherlands (I don’t live there but was just there on a trip)
Not anymore, I was for a couple years in Denver but that was over 10 years ago. Live in the burbs now but have a Brompton folding bike that I use for short trips to the grocery store and sometimes commuting to work. It’s so practical it’s amazing to take it into stores, use it as a shopping cart, and never have to leave it locked up. Just got back from the Netherlands and wow what a fairy tale society they have infrastructure-wise. The more I learn, travel, and see how some places in Europe are doing things the angrier I get with most of North America’s mentality/legislation.
I haven’t heard of that. I’ll have to check it out. Eastshade is really great for a calm, artistic environment.
