If you go to Bfold test ride the Reach while you are at it too, its more of a bike that folds than a folding bike.
The seat is in fact all the way back, but I put it there in the effort to get that knee-plumb-line test to line up correctly. At least I think if you see in the photos when you click to expand them, I think it's lining up properly.
Also I think the Pacific Cycles IF-Reach is an awesome bike... if they came out with an IF lightweight version with drops, I would throw my money at it.

Your ankle seems to be pretty rigid with toes pointing downwards most of the time so at the bottom of your stroke your leg doesn't extend as much as I think it should. Alternatively at the upper stroke your knee is bent more than I think it should be. Not to say your technique is improper, I'm just suggesting that because of it, your knees seem to be subjected to the same conditions as if your seat were too low which is usually a cause of knee stress/pain.
What length is your inseam and what length cranks do you have on the Verge? Also what is your usual pedaling cadence?
Interesting observation... I'll try experimenting with a higher seat, although if my memory serves correct, at seat heights higher than the video it begins to feel like I'm reaching. I'll try it though.
My inseam is roughly 32-33" (which is my pant size, I haven't actually measured with tape). Josh Hon from Tern says the stock crank is 170mm. I've been trying to increase my cadence in order to reduce knee pressure, but I'd say that on the road my typical cadence is probably around 80ish rpms.

No, I haven't had any major sports related injuries, but I think in prior years from running I might have had some knee weakness and foot plantar fasciitis. Hips and lower back are ok as far as I know, sometimes if I'm at the computer too long I'll feel a little soreness but nothing huge. Yeah I sit in the office a lot. And, I get knee pain in both knees--though it varies which feels worse; when I've done a lot of stop and go biking for example, my right knee can feel more sore since it's the pedal I mash on to get the bike going. That said, sometimes the left knee feels worse for whatever reason too. Ever since I started noticing knee pain, I've tried icing both after all my rides.
