"A cyclist can go 3 or 4 times faster than a pedestrian, but uses 5 times less energy. The bicycle is the perfect transducer to match metabolic energy to impedance of locomotion. Equipped with this tool, man outstrips efficiency of not only all machines, but all other animals as well."
β€”Ivan Illich, 1974.

@straphanger Would love to see ebikes on this chart. Must be somewhere between normal bike and motorbike, but I can't begin to guess where exactly.

@nix @straphanger it seems to be close to walking: https://eu.fiido.com/blogs/news/how-much-does-an-electric-bike-consume-per-kilometer

@nix @straphanger there's actually research that finds pedal assist ebikes to be more efficient than acoustic bicycles! A laptop battery and a 500w motor combined with muscle power on two wheels make for a very efficient vehicle

The chart backs up other studies that show humans walking or running are as inefficient as automobiles at turning calories into work. If batteries and motors improve on that then replacing all the humans with robots should offer the huge energy savings the future needs.

@nix @straphanger I have read they’re more energy efficient than pure pedal bikes because battery-motor power is much more efficient than digestion-muscle power.
