My city is just too hilly. Cycling around is one thing, and they just put in new bike lanes (they're not good ones, but still), but doing that with a grocery run or 60lbs of cat food and litter? No thank you.
Wife and I bought e-assist bikes, it makes it so you don't really have to work much even when youre carrying groceries
Weight speeds you up downhill more than it slows you down uphill. The trick is to not coast - keep pedaling downhill, use the momentum to get up the next hill.
Wat? The law of conservation of energy tends to disagree. Commuters are generally starting and ending at the same elevation so there's no trick. We're not going to convince anyone to carry heavy loads on bikes by saying "pedal more downhill to smooth out the power requirements if you hate grinding it out on uphills", the answer is just ebikes.
I'm just relating my experience - when I was younger, I commuted 20 miles round trip every day, and I worked at a bike shop with weenies that were always trying to shave weight off their bikes, so I did whatever I could to add functional weight (so no filling the tubes with lead, that would be cheating) including building up a dually, two rims side by side on a Sachs 3x7 hub. My average speed was higher when commuting (lots of rolling hills, but overall uphill in the morning, downhill going home) than it was on days off, when I was mainly riding around town where it was flat.
And it certainly wasn't because I wanted to go to work...
I appreciate your lived experience, but at the same time the rest of us will seek answers in basic physics concepts, none of which help explain such phenomenon. Is it possible you just got stronger or subconsciously tried harder because you wanted the heavy bike to be faster? Did you add weight but also make sure your bike was well tuned? Tire pressure and a greased chain go a long way. I certainly agree that the weight weenies can go way overboard though.
