Objective To model the impacts of the bicycle sharing system in London on the health of its users.

Design Health impact modelling and evaluation, using a stochastic simulation model.

Setting Central and inner London, England.

Data sources Total population operational registration and usage data for the London cycle hire scheme (collected April 2011-March 2012), surveys of cycle hire users (collected 2011), and London data on travel, physical activity, road traffic collisions, and particulate air pollution (PM2.5, (collected 2005-12).
