a new infographic every day
The top graphic doesn’t identify the bottom bracket and the chain stays
The recumbent ease-of-use is a “1,” and a unicycle is a “2″? Please…
In 50 years never hear of of a ‘steering head’. Do you mean the ‘steerer’ – part of the fork or the ‘head tube’- part of the frame? Also how do you figure a high wheeler is more efficient than a diamond frame racing bike or a recumbent? A kids tricycle is more efficient than a freight bike? Some science based and reviewed source would result in a more accurate product.
I thought efficiency (such as the penny farthing) was based on direct drive being most efficient, but that would have put the unicycle and tricycle at 4 stars, so that isn’t it. I am starting to think that whomever created this graphic equates speed with efficiency, thus anything going slow must be inefficient (I can’t think of a bike more efficient than a cargo bike!).
As someone else has already noted: ease-of-use for a recumbent lower than a unicycle? Only someone who has never tried could possibly make that “assessment.”
And then there is the mountain-bike-is-faster-than-a-BMX…ha!
