The Dash has a 14 - 28 cassette. Anything with a higher gear say 11 or 12 tooth are normally 7 speed at least which would not match the 6 speed shifter.
If you can find a 6 speed please post the details because as you say your legs are just treading air with the 14 tooth.

There is the Bike Shop in Glebe street Penarth that stock Freego.
Or if you wanted a nice day out in the country, Drover cycles in Hay on Wye stock Batribike folders.
I think you will find that it will only go so far before it sinks.
If you saw the recent Guy Martin programme he tried it on a converted motocross bike, before he got very far it sank like a stone to the bottom of the lake. :(

I'm sure it's a very nice image, but I can only see 2" on either side. :(
But thanks for spending the time choosing the image. :)
Obviously the first option in any collision with any motor vehicle would be avoidance. Failing that surely any protection is better than no protection at all !
It's your head so it's your choice.
