Becoming quite a risk, this subject. There's now a significant trend of bike shops being denied insurance because somehow the insurers have come to the idea that an e-bike is almost always a risk, when in fact all of the risk is coming from things that are not, in fact, e-bikes: https://www.cyclingelectric.com/news/call-for-government-to-up-pace-on-dangerous-kit-imports-or-face-existential-risk-to-cycling-industry
The state of data about ebike fires is so pathetic that its hard to make out what really causes fire. All that one hears about is charging, but there are several incidents of fire while riding.
Then articles like this make the data even murkier.

Referring to fire data apparently for 2022 , the article says
"As for the most recent data, the London Fire Brigade is again cited as a leading source. In this year, 46% or 74 of 161 fires labelled ‘e-bike’ were post-market conversions and nearly 30% of an unknown origin. 14% (29) were believed to have been manufactured goods, a lower proportion than the 36 e-scooter incidents."

When did 29/161 became 14%? Its 18%. Total doesn't add up to 100%. And, the graph for 2022 shows only ~3% for "manufactured" ebikes!

"The product presents a risk of fire as it has been identified that when the electric bike is being charged, it is possible for the lithium-ion batteries to go into failure mode, potentially leading to a thermal runaway and fire."

That doesn't sound like whoever wrote that recall notice had a clue what they were talking about. I'm not saying that there is or isn't a problem.
