I finally see how it is folded now.
It is a hinge apart and hook on bike.
Strida is half that way too. You hinge off
the crank boom and you hook on using
the plastic ring or the magnet that click
the wheels together.
On the GHbike "K" style model you hinge off
the steering tube and then you hook it on at the
rear wheel tube at some 50mm up from the hub.
You see on the front wheel the hook and on rear
wheel the other part that make up the hinge.
Sorry bad terminology.
so suppose each hub are 5 inch wide then the
whole package will be at least 10 inches thick
when folded. That is ok with me. All being made
of Alu it doesn't weight so much? Should be easy
to role it beside when entering Train or Bus.
Having a small footprint helps in crowded transportation.
So now we only have to find somebody who have access to
one K-bike and persuade them to write a detailed review on
how it handle itself and we would love a youtube on how it folds
It should take a bit more time to hinges off and hook together
again compared to a fast folder like BF Tikit?
