Manufacturing, generation of electricity with heavy use of fossil fuels (could be changed and is changing in many places, luckily) and particulate matter (for example through tire wear) mainly.

Still better than ICEs though.

And with those batteries, they're heavy as shit, doing increased damage to roads and bridges, and are outright disallowed on smaller rural / suburban bridges.

There's plenty of issues with making a fully enclosed vehicle sustainable regardless of drive train. Just the amount of metal needed of any kind.

They will probably always be needed for last mile deliveries or people with certain disabilities. That said, if we could get most North American cities to just 20% bike usage for people's major commuting choice, that'd be transformative.
