Amazon has a number of them, but looks like you could fabricate a cover with Neoprene fairly easily. FME, keep your battery inside before your ride.

I always keep the Battery inside in a cool dry environment before riding. I think I'll try to find some Neoprene and Velcro to make my own cover. Do a lot of fairly short trip riding in the 0-32 degree F days.....I don't ride below zero F as the windy air at riding speed is just too cold....

if your doing short trips don't worry about it. I see a little less range on my bosch powered bike but its not huge. the spare battery on our tandem will take more of a hit.

Problem with lithium batteries is not being able to charge at temps below freezing. Real advantage to having bikes with battery packs that are easily taken indoors for charging and for storage.

Question Battery Blankets or Insulated Battery Covers?

Hi all. I stumbled onto this thread and after reading it, I have a question. I just purchased an Ebike (being delivered today) and live in NJ where it gets pretty cold during winter months. I understand not charging in cold weather but rather room temperature, but should I be concerned about riding in cold weather? I assumed that the battery would do just fine. My commute will be 9 miles each way and the battery is a frame integrated battery on a Gazelle. Is there anything I should be mindful of? Do I need some sort of cover to cover frame the battery is sitting in?

Thanks in advance!

Nope. the only concern is slightly lowered range. 9 miles on a new battery should not be a cause to worry.

Operating in sub freezing temp is not a problem.
The cold affects battery life when it is stored at below freezing for extended amount of time (multiple days).
Store your battery at room temp (above 50 degree F) when not in use and you should be fine.
If the ebike has frame integrated battery, probably better to store the whole ebike indoors when not in use.

The question I have on this thread is - is this question for riding, storage, or charging?

For riding, don't worry about it. if it starts off at room temperature, it will generate its own heat. I've seen cars lose 30% of their range typically, but I'm not going that far in the winter on a single charge on my bike.

For storage/charging - definitely keep it inside at a decent temperature. I've ruined some nice batteries because I let them get too cold in the winter. Expensive mistake

I agree with Chas58,
As long as you take proper care of the Battery and don't plan a really long trip you should be fine. I ride just a few miles each trip in Cold or below 32 degrees F and the battery seems fine. So I will forgo the Battery Blanket.

Stanley, Idaho.... where is it truly cold in winter.

Agree with both GWG and C58. I rode my bike on an icy day in December, 2019 and didn't worry about the battery on a 3,000', 8 mile ascent that was probably a three hour ride since we stopped to throw snowballs etc. One guy rode his bike up and was carrying cross country skis to do a little skiing at the top. Only have the luxury of snow and low temps occasionally here (none this year so far).

I ride my fat bike in winter at temps down to minus 20 celcius and the 17.5 AH rack battery does just fine. Some rides are done later in the day where we stop at a ski cabin to warm up. On those days the bike is parked outside for about 3 hours. Our usual singletrack is roughly 8 km's one way and I,ve never had a problem. I have in the past wrapped the top and sides with a piece of closed cell foam and slipped a chemical hand warmer under the cover.
