"In the United States, a staggering 60% of all car trips cover less than 10km." Being lucky enough to live in a walkable city (NYC) this is insane to me. The world is so car-brained.
We don't need a 4000 lb vehicle to move a ~200 lb person. In order of efficiency: (1) Walk (2) Unicycle, roller skate, scooter (no battery, very little material) (2) Bike (3) Electric bike (and all forms of newfangled electric: escooters, segways) (4) Electric motorbike or scooter (5) Mass transit (can be public/private) transportation: Electric trains (6) Mass transit (can be public/private) transportation: Electric…
How are you defining efficiency here? Is walking really more efficient than cycling? I would put walking as the least efficient manual powered methods mentioned. Aside: I used to unicycle to work, and I have to say that it was both fantastic and much faster than walking while on a 27.5" wheel.
If everything around you is built with base assumption that you must have a car, then the optimization was done by someone else with a different definition of efficiency.

I wonder how this ranking might change if we also took into account the energy required to produce the extra calories that humans need to consume in order to get around via these modes of transportation. Like, you'd probably expend a lot of calories traveling 10 miles by unicycle, and over time maybe that would be more significant than the materials difference compared to cycling? Of course, it depends a lot on the d…

Energy efficiency is not the only variable that matters. Walking to my grocery store would take almost two hours each way. Biking would take 30 minutes each direction. Driving is 14 minutes each way, and is the only feasible way I can get groceries when I have my kids in tow (which sometimes is a necessity).
And of course not everyone wants to live in such a place, but plenty of people would. And in the US this is fairly rare compared to many other parts of the world.
Would anyone here like to recommend (or disrecommend) any e-bike models?

What does a salmon have in common with a man on a bicycle? They are both Pareto-efficient. Here's a chart of cost of transport (calories/gram/km) vs weight (kg) comparing a salmon vs a bicycle vs a jet fighter etc: https://www.bike.nyc/wp-content/uploads/2017/04/efficiency-g...
Fun! But how to read the Y axis? Why does it start from 1 twice?
Those go 0.1, 0.2, 0.4, .. 1, 2, 4, ... 10, 20, 40...
I am guessing they printed "0.1" as ".1", and because it's a really bad scan the ".1" and "1" look identical.
I do almost all the grocery shopping for our family of 4 with a Rad Runner Plus with a large basket and bag. I love that bike. Even as someone pretty comfortable getting around on a 'regular' bike, having that extra power just makes it a really easy choice for more trips compared to the car. If it's hot out, it is so much nicer to hop on the bike and get an instant breeze compared to a hot stuffy car. If it's cold ou…
