Non-cyclists have been found to have an all-cause mortality 39% higher than those who cycle to work, even after taking other factors into consideration. (Andersen et al, 2000)
Non-cyclists take up to 18% more time off sick than regular commuting cyclists. (Hendriksen et al, 2010)
Recent estimates suggest that the health benefits from physical activity outweigh the risks by up to 77 to 1. (Rojas-Ruede et al, 2011). A British Medical Association study found that even with hostile traffic conditions, the benefits gained from regular cycling outweighs the risk of loss of life by about 20 to 1.
A Copenhagen population study of 30,640 individuals over 15 years found that mortality in cyclists is 39% less compared to non-cyclists. It increases again for those who decrease their level of cycling.
There are 8 million cycle trips for each cycling death and 27 million miles cycled for each death – equivalent to over 100 trips to the Moon and back or 1000 times around the world.
Cycling safety has substantially improved in recent years, although at a slower rate than for most other modes. Cycling was 61% safer in 2012 than it was in 2002 (per mile travelled).
