I walk past Little Italy (hipster area) all the time, cyclists abound merrily riding over sidewalks, and I have to keep looking over my shoulder. I had collisions a couple times. Most other busy areas close o downtown are in similar situation. I feel bad for senior citizens. 

These bikers on sidewalks are arrogant enough to hog the area to the point of edging out pedestrians. Only core downtown is safe, but even there many people I observe, keep looking over their shoulders, perhaps for some imagined homeless-mugger. 

The kitted male bikers are reasonable and keep to the road. Female bikers and very young males, accidents waiting to happen.
