Tube Portable Bikes - which are cooler?

Some of you may have seen an ad on the London Underground for Ridgeback bikes as the "cool way to get to work". However some people still have to get their bikes on the Tube and portable options seem to be getting more popular, as not all Tube stations let you carry full sized bicycles, particularly not in the rush hour.


I've seen a lot of portable bikes over the last few weeks, but which do you think are actually cooler?

Is it the classic fold away Brompton?


Or this Nathan Barleyesque scooter?


Is the retro Micro Scooter back in style or is the Brompton still king?
