@amey I love the Douze. Compared to a Bakfiets it's very light, and from the few goes I had on a Bullit I would say it's comparable in weight and speed.
The cable steering is great and makes for tight turning circles, especially when pusing and trying to get around bollards and the like. It tracks great in a straight line and you can ride it standing up easily, even with a kid in the cargo area.
I have the step through version with the 600 front bit. Step through might feel a bit more flexy than the non-step-through frame, but for me that's a non issue.
Size wise, being 186cm tall I am really pushing it here with the saddle all the way up and set back, but if you're smaller it should be fine. The steering column I have is height adjustable, but the seat post kept slipping with a quick release and my wife didn't want to ride it anyways, so I got a decent clamp.
The cargo area seemed a tad wider than the Bullit but waaaay smaller than a Bakfiet. The box is a Cordura outer which is fixed with velcro around some aluminium rails. There are clips around which hold in place a Cordura top cover. Super light and all pretty much waterproof when riding or parked outside. Inside there's a soft seat for the little one in it.
Cargo wise it's pretty capable. My daughter is about 22kg now and 1.20m tall. She has to pull her knees in but still fits very comfortably. Or a bit more crowded if we also carry some shopping.
I like the bike so much that for around town, it is my goto bike now.
