Looks like there has been 37 cases of ebike battery fire in Japan. 😲
They're recalling 346,291 affected units, sold between Oct 2012 to Jan 2015.

Not all 2012-2015 models were affected, Panasonic is asking customers to check the serial #.
Some of the packs that go behind the seat tubes had fire problems.

I wonder what kind of fires - while in use, in charging or other. The bike on the photo is beautiful, btw. Smooth curves, chain cover, double stand - is this too much to ask?

I have been trying to get some details, what I gathered was that basically humid air in Japan caused moisture in the pack and caused the some kind of chemical reaction to ignite the battery.

Btw that's a typical ebike in Japan.
They're 250W mid drive (if it has hub, usually with re-gen), limited to 15mph, usually around $1,000 give or take.
