Current Market Situation We asked 50 people:

Only 15 % think BikeSto is NOT a good idea

70 % would subscribe monthly instead of single usage

In the student dorms a lot of potential customers

Slide 4

Future Market Demand (1/2) “…2005, was a record year for the production of

bicycles in China with a 16% increase in the production of bicycles and E-Bikes to a total of 80,430,000 units produced, of which about 65% were exported”1

“The share of all trips made by bike varies greatly among countries. Chinese cities still register some of the highest cycling rates in the world, despite growing consumer interest in private automobiles. In the most cycled cities, such as Tianjin, Xi'an, and Shijiazhuang, the bicycle accounts for more than half of all trips.”2

“With expanding urbanization, longer travel distance and increasing salary, e-bikes has been developing at an unprecedented speed in China. The annual production of electric bicycles in China has grown from 58,000 in 1998 to 27 million in 2010.”3

“Besides commuters and elderly people, students especially high schools students are becoming an important consumer group of e-bikes.”31 http://www.worldometers.info/bicycles/
