In terms of form-factor, if you've folded and carried one, other brands are very similar. If you want a "frequent folder" for daily folds and multimode transport, you may desire a folder with smaller wheels and smaller fold, like a Brompton or clones (referred to as Brompnot, there is a recent thread about those), those have 16" wheels and a "trifold" frame that folds MUCH smaller than any bifold frame. If you're unfamiliar with either of those styles, you should handle one in person before buying online.

EDIT: "Light enough for travel." Details please; car, train, or flight?
