“Cycling confers individual and population-level health benefits, including benefits from decreased cardiovascular risk, improved mental wellbeing, decreased check details air pollution and decreased exposure to road traffic collisions (de Hartog et al., 2010, Lindsay et al., 2011, Pucher et al., 2010a, Pucher

et al., 2010b, Rojas-Rueda et al., 2011 and Woodcock et al., 2009). Yet levels of cycling in the UK remain low (Department for Transport, 2010). Promoting active travel is now high on the public health agenda (Douglas et al., 2011) and public bicycle sharing schemes have become a popular intervention, with an estimated 375 schemes in 33 countries around Selleck KU57788 the world (Midgley, 2011). In the UK, London’s public bicycle sharing scheme, the Barclays Cycle Hire (BCH) scheme, was introduced by the public body Transport for London in July 2010. At its launch, the scheme comprised 3000 bicycles located at 315 docking stations throughout central London (Transport for London, 2010b). When registering, individuals pay until £3 for a BCH ‘key’ and then choose between 1-day access (£1), 7-day access (£5) or annual access (£45). After paying the access fee trips of under 30 min are free but longer trips incur additional usage charges. Registration was compulsory prior to 3rd December 2010, but since this date non-registered individuals have been able to buy 1-day or 7-day access as pay-as-you-go ‘casual’ users.

A debit or credit card is required to pay for keys, access and usage charges (Transport for London, 2010a). The BCH scheme is one of the Mayor of London’s initiatives to increase London’s modal share of cycling from 2% to 5% by 2026 (Transport for London, 2010b and Transport for London, 2010c). There are, however, concerns that interventions to promote cycling may be inequitable, with levels of cycling uptake in the UK higher amongst affluent white men (Marmot, 2010, Parkin et al., 2008 and Steinbach et al., 2011). While the aim of the BCH scheme was not to reduce inequalities (Transport for London, 2010b and Transport for London, 2010c), it has been argued that the health and equity impacts of all public investment projects should be evaluated (Kahlmeier et al., 2010 and Ståhl et al., 2006). Despite public bicycle sharing schemes existing in many other European and North American cities, evidence reviews have identified few published evaluations (Pucher et al., 2010a, Pucher et al.
