I've been doing a bit of street research (chatting at traffic lights whilst riding to work) with cyclists, and one of the main reasons people cite for not buying folders is that they look a bit odd with little wheels and enormous long stems and seat posts. I've tried a few bromptons and a dahon and find that the small wheels retain less inertia, so are more tiring to ride. They also feel less stable. (though I'm sure you'll all correct me on these points)

I do mean 26" wheels yes. The advantages of larger wheels must be obvious to most people or ordinary bicycles wouldn't have had 26" ones since the dawn of time?

I'd eventually like to develop a mountain bike in the same vein as the urban one i'm working on, so starting with larger wheels seems logical.

It sounds like those pesky Germans have stolen my idea then...

Thanks for the feedback, however malevolent!
