As some of you know from my previous posts, I'm thinking of another folder to augment my Brompton when I don't need compactness (better wheels for harsher conditions, a bit more speed, etc.). I was fixated on the Dahon/mini-velo style (smallwheeler's thread is not helpful... ), but I've sort of settled on three options.

1. Dahon Silvertip (mini-velo style). 20" wheels provide a bit more versatility; bit stiffer ride; still agile; decent price; fairly adaptable to standard parts (racks, etc.). However, not sure about long term integrity of lock jaw fold, and not overly convenient to fold (but not looking for fold as main point). Not sure how easy it is to pack for travel if I want to do some semi-serious riding at destination.

2. Used Bike Friday (New World Tourist). 20" wheels; standard bike parts; seems most forgiving ride. However, still most expensive option even when used, and none available locally to check out.

3. Older Dahon Jack or Tern Joe. 26" wheels - might be most usable in poorer weather or winter with the right tires; can fold in half easily when needed so offers some portability; should ride pretty much as a regular bike; decent price. However, wondering if the increased size makes folding all that critical. Ironically, less gearing or other choices. Not sure if a rear rack can be mounted. Trying to see if a Dahon Jack or Dahon Espresso is better.

... and I can't find any good review comparing the Dahon Jack against the Tern Joe.

The primary use would be commuting (less than 15 minutes) and short errands, and if possible, occasional travel.

Thoughts? Pros, cons? Not worth my time or money?
