I own a Pocket Pilot and a Pocket Tourist. Here are a couple of thoughts regarding models.
NWT- 406 wheels. You can run a lot wider tires than either the
PR or PP. If you plan on riding on bad roads or 406 tubes and tires are much easier to find than the 451 size on the
PR or PP..
Pocket Pilot- The PP is considered a stock bike and BF doesn't allow changes to the component specs nor can you get a custom frame. The size is selected from 3 or 4 stock sizes...
The removeable seat mast is easier to pack than the foldable seatmast on the
PR or NWT
Pocket Rocket- Offered in custom sizes. Slightly lighter than the PP..You can order with a custom 1 piece stem(it's an after the fact order on the Pocket Pilot)
I choose the Pocket Pilot because I wanted to add my own components. I also really like the removable seatmast. I have the mast marked with a line for the proper seat height so I just undo the quick release. I find this easier than removing the seat post every time I have to pack the bike.
You really can't go wrong with any of the above bikes.
