eBikes really take the sting out of hills.
I live where it snows a lot, winter tires are a must, but so long as bike lanes are properly cleared it’s not really a problem (big IF I know), until it gets to -25C or colder the cold isn’t really a problem (you warm up fast peddling, I normally find myself unzipping my jacket).
My cargo bike is enough for me to take 2 weeks of groceries for 4 people. The largest thing I have transported has been a fridge (which funnily enough couldn’t fit in my EV). the bike is rated for 200Kg, but I would bet it can take more if you don’t mind going a little slower. I have also transported lawn mowers, bar stools and a rocking chair. For anything bigger than that 30bucks on a uhaul is more than worthwhile, although I look forward to electric uhauls.
E-bikes still have a massive carbon footprint compared to regular bicycles, and the battery efficiency is very adversely effected by high heat (deserts) and low heat (snow) .
Either way, a car, even if its an EV, will be the better pick for every situation I stated above.
