Cyclists can also respond in some emergencies, including some that aren't available to joggers. For example, I found that two wheels + two feet made it possible to travel on an icy road where two feet alone felt very dangerous. Cyclists also very rarely get a sprained ankle. I don't find where "falling off a bike almost always ends up head-first." My own injuries seem more of the slip on an icy or wet patch and fall on my side variety. Looking around, according to http://books.google.com/books?id=cxn2dKfCg1AC&lpg=PA138&ots=7tFEvEPrNy&dq=bicycle%20accident%20injuries%20%22broken%20bone%22%20head%20abrasion&hl=sv&pg=PA138#v=onepage&q=crash%20relaed%20injuries&f=false http://books.google.com/books?id=cxn2dKfCg1AC&lpg=PA138&ots=... "gravel rash" on the hips, knees, butt, and elbows is the most common injury. Bruising, cuts, and breaks (collarbone, ribs, and wrists, in that order) are relatively less common. I don't get a sense that head-first events top the list.
