It's always good to have a resource of updated information even if the OP has long bought their bike. When looking for features, they may not have been available at the time the question was posted. The Tern BYB could be added to this list but at the asking price in Canada, it would have to be something exceptional. I'm a firm believer that over time any design wiith multiple splits for hinges will develop movement so my preference is for a solid frame with a tuck under wheel such as the Ahooga, Brompton, Chedech & IVE. I'm sure there are others & Ahooga seems to only sell in Europe. All these models can be rolled when folded.
