I live in SW Florida. There are thousands (hundreds of thousands?) of e-bikes here. They are more common than regular bikes. I haven't heard of any fires in the last 8 years that I have lived here. I suspect, but don't know for sure, that the sizes of the battery packs aren't big enough to generate the heat required to ignite them. Most of the e-bikes run on 48 volts or less. The e-cars run 350 to 400 volts.

Retirees putt around the neighborhoods at about 10mph but those whom we might call “Florida Man” use them as primary transportation and cruise along closer to 20mph on the major roads. Most of the “Florida Man” group have lost their licenses to drive because of DUI convictions and are very likely to still be under the influence while riding e-bikes.

It isn’t that, it’s just that the OEM charger-battery pair is safe when unmodified and undamaged and operated within normal range of conditions
