Things I had success doing when my city was spending zero dollars on bike infrastructure:
1. Creating & printing a bike map
2. Removing "No Bikes" signs
3. Installing public bike racks
4. Organizing cyclists
5. Planning bike lanes-- some got included in long-term plans
6. Convincing the city to ask the DOT for a "complete streets" approach on a state road
7. Putting "Complete Streets" in long term plans.
