I saw this and immediately balked at it.

He sees potential buyers as being people who want to cycle to the nearest rail or Tube station and also those who want to avoid London's congestion charge.

Look at the size of those wheels, they cannot be safe for use on a road!
The rider would surely be catapulted from the bike if they ran over a small stone or the tiniest of potholes (there would be a few of those in London :roll: )

Is there anyone here who thinks this is a good idea?

sure... it'll prove you need at least moulton sized wheels for a decent ride and hence some space on the train to transport them.

Assuming a 60rpm cadence at 12mph and 6 inch diameter wheels, I just worked out that there needs to be 1:11.2 upgearing between pedals and driving wheel.

How do you do that then? A gear train?

A lot of go-ped type toys have similar sized wheels. How do they fare in the real world? Do they keep tripping up? <serious question!>

I saw a short clip on BBC News 24, and it does fold up very small (about laptop case size), and appeared to go at a reasonable speed, but not too fast. However the first thing that I thought when I saw it was: "Those wheels are much too small, just go over a drain cover and the wheel will immediately go straight through, and you over the handlebar". Then I remembered, that the people using it will probably be riding on the pavement anyway, so no problem...!
