You also need to include regen. And the fact the tank has a weight.
1kWh/kg is roughly on par with a small reciprocating ICE.

The fuel tank is made from thin plastic so the weight is largely irrelevant.

They're still >20kg when plastic, and the last few I saw were steel and weighed as much as the fuel.

i think ICE engine and specific parts add more weight than their electric counterparts.
