Lifecycle emissions of ebiking can be a couple times lower unless you eat very green. Its been regularly over 100F here and I wish it was a desert so I didn't have to also deal with humidity: I've ridden in thunderstorms and think its nicer than riding the middle of the sunny summer days. Either way, still better than driving in traffic. For moving large things, a car is not any better. And driving around a moving van every day would be a huge waste when you can just use them when you need them and drive a much better vehicle (a bike) when you don't.
