Ironically the ones I purchased are all folding models. In some ways the folding models are the worst weight wise, the extra hardware needed to strengthen the frame makes them incredibly heavy. I own a very nice Tern Vektron, one of the higher end folding electric bikes, and I've folded it once, it's just way to heavy for folding and carrying to be practical. I'd sooner walk than try and move it around a busy train, for example. The fold is really only useful for storage at home.
