I keep watching the video and it does seem a good shape to move around but it's still a large package. Look at how much space it takes up in the boot of the car. It also seems a difficult package to manuvover ,it does really roll except on very smooth surfaces. It looks great as a one bike solution that can be used on trains or off road. It's light weight is a bonus for carrying that makes up for a lot of compromises.
I will be really interested in seeing if a 20" bike design that folds as small as a birdie or Brompton that preforms with this potentional. I hope it's intinal success leads to a 20 or even a 16 inch model.
