*3.5. Social Competition for the Promotion of Physical Activity*

The objective of the proposed system is to promote users' physical activity through the cycling of routes on electric bicycles. Thanks to social interaction through the application, users are motivated to compete with each other by increasing their physical activity. As described previously, the application implements a social component in order to provide users with a comparative of their progress. The system generates three different rankings on the application; general ranking by area (includes the scores of users in the same location) which shows 10 users with higher scoring. Another ranking with users who have similar profiles (age, gender, routes cycled, the number of routes cycled per week). Finally, a ranking with the user's friends on Facebook. The *ebikemotion* application has native support for Facebook, making it simple for users to find friends on the social network through the application. Eighty-six percent of current *ebikemotion* users have their Facebook account linked to the application, this shows that social interaction among users is high.
