A University of Sydney study of 846 inner-city commuters found cyclists had better overall quality of life and health satisfaction than public-transport users, walkers and motorists.

Statistical adjustments were made for other possible explanations such as age, sex, education and income levels, lead researcher Melanie Crane said.

Cycling involved mental-health benefits of being active outdoors, a greater control over and predictability of their commuting journey, a sense of fun and a way to save money, she said.

‘‘This may be why cycling commuters arrive for work in a happier mind frame than other commuters.’’

The research, published in the Quality of Life Research journal, is part of a three-year study on changes in travel and health behaviours as a result of new cycling infrastructure.

Commuting cyclists are twice as happy as people who drive, walk or use public transport to get to work, new research suggests.

The region’s council leaders don’t underestimate the power of the pedal and are encouraging residents in Wollongong, Shellharbour and Kiama to get on their bikes and ride.

‘‘Cycling not only has a number of health benefits, it also has a positive impact on the environment," Shellharbour Mayor Marianne Saliba said.

It  took  around 5 per cent of the materials and energy used to make a car to build a bike, which   itself produced zero pollution when used.

‘‘The Illawarra region has some of the most scenic cycle paths in the state, which make it possible to ride from one city to the next along foreshore and country areas,’’ Cr Saliba said.

Bike Week events include the Wollongong Ride the Gong, Shellharbour Bike About and the Kiama Classic Family Fun Bike Ride. For details visit your local council website.
