Short update ...

We have 400 or so miles on the Merc now. I installed a set of skate wheels but needed to buy a longer set of screws to securely fasten the wheels. (If you are wondering, I used M6x1.0 50 mm machine screws) Since someone is always getting rid of an old set of inline skates, this is a cheap upgrade. My wife has a much easier time moving the bike now.

I doubt that we will use it for touring or the such; but it is great for doing around town chores and such. I am calling a local welder to install brake bosses for a set of v-brakes and getting a better seatpost. As opposed to the Brompton extended seatpost, we decided to go with an EVO version to get rid of the silly penta-clip and saddle adaptor.

One could also use the standard Brompton telescoping seatpost and replace the extended part with any 26.6 diameter seatpost. It is a somewhat difficult size to find; but not impossible.
