It does look quite cool, but it also looks like it's bigger than a Brompton, but with smaller wheels (12"?)

I test rode the Brompton S2L-X the other day, I loved the bike but I think it's ridiculously overpriced. It was fast, stiff, comfy and Brompton have finally put decent brakes on! And they still have the most compact fold out there. I also really like the front luggage system on Bromptons. The thing is - I look at the Brompton price tag, then I look at how much more I could get for the same money from another manufacturer...

I don't know what the Frog costs in the USA. Here in the UK it's fairly expensive. I tried one last year and rather liked it. I wasn't very impressed by the fold though, and I think a backpack is the only option for carrying luggage on it.
