I own a TernJoeP24, and I have a Dahon Speed P8. The TernJoeP24 isn't an easy fit in a vehicle, as some might think. The Speed P8 is an easy fit.

As for long distance rides, the TernJoeP24 is easier to go the distance straight out of the box. With a better saddle, and a few other upgrades (if desired), the Dahon Speed P8 is just as good. Well, not as good on hills (8 speeds vs 24 speeds), but doable.

Now, has the OP considered a Downtube folding bike? Solid specs, excellent price, and a warranty that works. Plus, the owner is a forum member and answers all questions directly.
