Why are Chinese bike-share companies struggling to replicate their success abroad? Ed Butler hears from Nick Hubble, a cycling campaigner in Manchester - the UK city where Chinese firm Mobike has just scrapped its bike-share scheme. Mobike's head of growth in Europe Steve Milton describes the challenges of global expansion. Julian Scriven from rival German firm Nextbike explains why the Chinese model doesn't necessarily work in other countries, and Dana Yanocha, Senior Research Associate at the Institute for Transportation and Development Policy in Washington DC, describes the challenges faced by US cities swamped by shared bikes.
