Well, as many of you know, my CFS, Gulf War Syndrome or what ever you want to call it is mainly helped the more I ride my bike, so I ride where no sane people in my area do. 
I went out today on the way to church, and it was just under 30 F and like an idiot, I decided to wear 2 layers (rain coat and long sleeve shirt) and was quite hot and sweaty once I got there.
I have to say, I'm very pleasantly surprised with the performance of both the EBoost (Kepler) Drive http://endless-sphere.com/forums/viewtopic.php?f=31&t=20491
And the 4S Nano Tech 25 - 50C Turnigy LiPo packs http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=11940 that I sort of grudgingly paid extra for hoping that they would be significantly better than the average LiPo pack at Hobby King.
I had been in a Frock (Hub) Motor mind-set when buying these, thinking I was going to want to run the EBoost drive at 8S, and that would give me the hill climbing performance I needed, as this was my first foray into the RC world, as they say I didn't know what I didn't know yet!
SO I bought these to run 2S 3P so I would have 30V and 18 AH of LiPo goodness, and I used the ABSOLUTE wrong motor (against many on-looker's advice) that I bought at my local hobby shop, and burned up the motor and ESC since I had really no clue, and was going WAY too high on the kV (295!!) and voltage.
Fast forward to now, I thought, well shoot, what do I do now? For most LiPo you need to run 5S to get the power you need for this type of friction set-up to hit the sweet spot of about 23 MPH on the flats. I am doing that with these batteries and only 4S or 15V nominal, 3 packs in parallel, so 15V 18AH!

I have been using nothing more than self adhesive palm sander sheets with 100G sandpaper from Home Depot (get the stuff with the plastic back not paper), about $4 give you enough to wrap the 63MM motor 8 times, I have gone about 30 miles now on this, and no problems with wear or slipping even in the rain!
Well that was all good and fine, been climbing hills at 16 MPH that normally I could only do at 3 -4 MPH my own pedaling on a regular bike, or 7 - 8 MPH with my 350Watt geared hub motor, and I got the angle of the drive right after some trial and error, and NOW I have been riding in sub freezing weather.
Here are the pics and the results!
Nice sunny day, just below 30F when I left the house.
Love the traction of the continental top contact tires! I have a cheap kenda on the rear atm, but I siped it, so it did fine too, no slipping, and I even used the clips! (probably not a good idea on ice though hehe )
And here are the stats on the watt meter, the bike had been ridden previously to the LBS a few days previous down and then up the big hill (the one I hit between 38 - 41 MPH going down ) where I was able to hit 16 MPH going up 8% grade with medium pedaling effort, and then on the same charge (had only 4 AH's used for the first trip) and then another 4 miles today bringing up to 5 AH's used.
Even in this sub-freezing temp, I am getting full speed on the flats out of the motor! 21 MPH with a light head wind on the flat, voltage sag only down to about 14.4V average from 15.4V at rest! Gotta love the Turnigy Nano Tech! 8)
Ok, now that I got it working great, my next test will be to go back to 8S and see how the 63 - 74 -200 Turnigy motor handles it, and I will do this with a 26" MTB (most likely my cargo bike build while I am waiting to afford the Nu Vinci) I should be getting around 40 MPH out this set-up! 8) 8)
This will only be for motor testing purposes, I will not be using this on the public road. Fortunately for me, my neighbor across the street has a REALLY long drive-way that I can use for my drag strip! (gotta love living out of the city limits hehe) So long as no cows get loose or deer jump out from the field next to the drive-way, I should be able to do a nice little "melt down" test (Hopefully it's just a wild ride with no melting! ) and if I toast the 63- 74, I have another one ready to replace it.
