Explanation:

The first piece of evidence is about bike - sharing reducing traffic (by providing an alternative to traditional transportation). The second piece of evidence is about bikes being good for the environment (no greenhouse gas emissions). These are two additional positive aspects of bike - sharing. "To be sure" is used for emphasizing a point that is already known or accepted, which is not the case here. "Nonetheless" is used to show contrast, but there is no contrast between the two pieces of evidence. "In addition" is used to add another point, which fits well as the second evidence is an additional benefit of bike - sharing.

Answer:

In addition
