Bicycle weight and commuting time: randomised trial.


ABSTRACT:

Objective

To determine whether the author's 20.9 lb (9.5 kg) carbon frame bicycle reduced commuting time compared with his 29.75 lb (13.5 kg) steel frame bicycle.

Design

Randomised trial.

Setting

Sheffield and Chesterfield, United Kingdom, between mid-January 2010 and mid-July 2010.

Participants

One consultant in anaesthesia and intensive care.

Main outcome measure

Total time to complete the 27 mile (43.5 kilometre) journey from Sheffield to Chesterfield Royal Hospital and back.

Results

The total distance travelled on the steel frame bicycle during the study period was 809 miles (1302 km) and on the carbon frame bicycle was 711 miles (1144 km). The difference in the mean journey time between the steel and carbon bicycles was 00:00:32 (hr:min:sec; 95% CI -00:03:34 to 00:02:30; P=0.72).

Conclusions

A lighter bicycle did not lead to a detectable difference in commuting time. Cyclists may find it more cost effective to reduce their own weight rather than to purchase a lighter bicycle.
