As someone who only owns folders, I can see the motivation for folding e-bikes is very different from regular folder riders. Most regular folder riders do so because of the ease of multi-modal transportation or travel packing, and these e-folders don't really fit those requirements.
Too heavy by far. Seems like mostly they are less expensive options compared to regular e-bikes that people choose. Not a bad thing, just interesting to me. Regular folder riders obsess over the ride quality of their bikes first and foremost as they are often used for touring and very long rides, and then become weight weenies. The e-folders are used very differently it seems. Almost a completely different class of folder. It's really interesting to see how the addition of commercial motors has developed a new design and target audience. I wonder if it will lead those people to ever try regular folders.
