Chinese bike-sharing company Mobike entered the Latin American market in Mexico City this year drawn by its millions of potential clients. Now it has run into a problem increasingly plaguing the country: street crime.

Theft has been so widespread that in the past few days, dozens of the app¡¯s customers have complained on social media about the lack of available bicycles. Many of them told Reuters they are thinking hard about switching to the competition.

Mobike, the largest bike-sharing company in the world, said shortages were due to theft as well as growing demand for the 500 bicycles available in a small part of the capital while it awaits clearance from city authorities to expand further.
