I would strongly encourage you to be cautious while testing the lower operational limit - make sure you have a backup plan for transportation if the bike shuts down (or more likely, refuses to start up after a cold soak) while you are exposed to the environment. I don't know what the freezing point for the electrolyte in the batteries is, but you obviously want to avoid that as well. (EIG says -30C / -22 F is the minimum storage temperature).

All that said.. I'd love to read what you find out.

I work at home over the winter, so it would just be around the neighbourhood. Definitely not into being stranded on a gravel road in winter!

The batteries and electrics will heat up as you use them so if you set off from a warm garage and park up back in a warm garage it should be fine.  Unless the bikes has an external temp sensor, which I doubt.

Hey, what do you all do for neck-warming when riding in cold temps?
I used to put on a balaclava, but it made my helmet too small.
I've been using a plain old scarf, which has been surprisingly effective.
Although I'm not getting many cool rider fashion points, I'm sure.

Something like this?

It's not perfect but I ordered it for 4€ and it works good for me.

This is what I use:
http://www.cyclegear.com/eng/product/neck_guard/web1000778

It's kind of a pain in the ass to put on, and it's a little too short in the back for my jacket, the end often will slip out.. but it works very well.

36 degrees when I rode in this morning. Testing brush guards that deflect wind - installed only the left guard, had to rezip the grip control cable. Wore my summer gloves, left hand was cool but fine when I got in (~13 miles ~25 minutes), right hand was pretty damn cold.

I need to figure out how to install the right guard. I may move the mirror / brake grip mount down the bar and install the guard clip right beside the control pod.

Had to leave my bike at the station last night because we got ~5inches of snow in a Nor'easter!

I've been riding in 30-50 degree weather lately and noticed that the range is not significantly affected until temps fall into the 30's.  The range I've calculated (for mixed 50/50 highway/city driving) is usually around 75mi at temps above 40 degrees, but in the 30's in the same driving conditions, predicted range is closer to 65mi.

About 34F on the ride into work this morning.   
when I turned the bike on, I got a blink code on the display  :o
5 short, 1 long.  ???  Clear as mud!  It went away when I put the kickstand up.  So I rode home, no problems.
Turns out the blink code is "kickstand sensor error".  Bet it's a connector that has a temp sensitivity and goes away when it warms up.


I had trouble starting my bike this evening when I got home on the train - a heavy dew had fallen and the temp had dropped to about 5C. Took several attempts to get it started. And the regen braking was very jerky for the short ride home. What gives?

When you say "several attempts to get it started",  I assume you mean you turned it on, got lights etc, but it wouldn't respond to the throttle?  And after several power cycles it decided to go?  Any blink codes?

Recently I have been having a minor problem with my bike not responding to the throttle upon startup in the morning.  I keep my bike garaged and the temperatures in the morning have been above 50 degrees F.  This happens about one in 10 times when starting up and happens in both Eco and Sport mode.  It only seems to happen when the battery is fully charged.  Rebooting once always gets me going again.  It doesn't really bother me that much, but I hope it doesn't get any worse.  I can't find any pattern to this minor glitch, other than it does it when fully charged.

Recently I have been having a minor problem with my bike not responding to the throttle upon startup in the morning.   I keep my bike garaged and the temperatures in the morning have been above 50 degrees F.  This happens about one in 10 times when starting up and happens in both Eco and Sport mode.  It only seems to happen when the battery is fully charged.  Rebooting once always gets me going again.

I've noticed that too, same exact symptoms.  Started about a month ago.  It's been colder here for sure, but a month ago is also about when I got the "glitch" sevcon controller software fix.  I've been trying to correlate it with an activity - so far it's only happened when I turn the bike on, then manually push it backwards about 10 ft out of the shed, then try to go.   So far if I back it out, then turn it on, it's OK.   The theory is the backwards movement from the encoder is freaking out the controller??

As much as I know it is an effect of the new Software.

The SW has a different pre-charge algorithm that need more time.

Unfortunately it produce sometimes a pre-charge fault and you need to turn the key off and on again. :'(

But better as a glitch, I still have the old SW and two days ago I started to overtake a Truck and my bike stopped  :o (it was the first time I got the glitch)

My "glitch" has nothing to do with rolling the bike backwards.  When I leave my garage, I roll my bike forward, place it on the side stand, turn the key on without moving it, then I wait for the computer to boot up and let the dials and lights come to a rest, then I turn the kill switch on, mount the bike and turn the throttle.  Most of the time the bike rolls forward, but sometimes it doesn't and has to be restarted again.  Then it always starts up and I have no other problems for the rest of the day.  No big deal, but it is kind of strange.  My bike has had all of the updates and recalls performed.  I might add that this first happened the day after the factory returned my bike after they fixed the encoder problem.
