A few weeks ago, I was in my local bike shop in Brooklyn waiting on some repairs. The bike shop sells mostly regular bikes, but some e-bikes too from name brands like Specialized and Trek. I was chatting with the owner about e-bike fires, which have been making the local news recently. As we spoke, a young man walked in and asked the owner if they do e-bike battery repairs for a specific brand. The owner said they don’t carry that brand so they can’t do repairs, either. The man said, “OK, I guess I’ll buy the battery I saw on Alibaba then,” and walked out.

“And that’s how you get fires,” the owner said.
