We see a proliferation of bike sharing services. Given that most shared bikes are kept outdoors all the time, I wonder what components and designs help to make them robust in order to keep maintenance cost down.
Here is a number that I found hard to believe, quoted by Horace Dediu on Twitter: Chinese dockless bike sharing companies employ one maintenance worker per 1000 bikes. Western dock systems are close to one per 30.
Addendum: From the Financial Times 26 Dec. 2017 "China bike-sharing apps find UK market tough to crack": According to Mr Seal-Driver, in Cambridge there are 23 operational staff for 450 Ofo bikes. Steve Pyer, UK general manager at Mobike, which does not employ people directly but uses third-party partnerships, says there are about 10-15 people for every 1,000 of its bikes.
