Man I wish the bigfish was still a thing. Briefly was available in the us and can kick myself for not getting one.
You should check out Origami and maybe MyBikeFriday.
The big fish had this unique mechanism so that the ride geometry was the same as a full size bike. I had a folder and the weight ratio being back heavy was the main issue. Would love to get a Montague M-E1 but don’t have the dough for that right now. Would actually love to get the non electric version but they discontinued it. I think they figured if the folding convenience was something someone wanted they would put up with the cost and extra weight and having two types just splits the customer base.
Eh, I like my Priority Folder pretty well but bike fit can be a trick thing even when everything is adjustable.
Don’t get me wrong I used my folder for years and liked it but more well enough. You can bring bikes on trains and busses here but there are limits on how many and restricted times and with a folder you never had to worry about it. I have was tempted by the original A-bike as even though it seemed limited it felt like you could wheel it through a store and use the front basket as your store basket. Thats another way of the dodo one but it used the super small tires although its hard to say but its geometry may not be that bad. I think one thing with me is I like an upright position. On my old folder if I lowered the handlebars and bent forward the weight distribution was closer to equal. I also would hang my bag on the bars to push more weight forward.
