That is on the very very very high end for track racing. 90% of trackies would say it is too high for racing. Which means it is way too high for any street, in any place.
I would recomend you get a 17 or 18 tooth cog for your 48.

God damn, you need a lot of external validation for your gearing choices. Just try whatever stupid gearing you want, and if it works, you'll know.

are you trying to go as slow as physically possible on a bicycle? youre certainly not averaging 40 mph in nyc. only if the entire city was a ghost town would you even reach > track speeds in the streets
why do you want to use such a high gearing in the first place?

Way too high for urban. Especially NYC. You got a deathwish? You looking to have double knee replacement in your early 30s?
My gearing is 48x15 fixed, but I live rural and most of my rides are traffic light/stop sign free and rolling hills. For me it's a fitness thing. The only strain is getting started, but once I'm up to speed it's 90-120 rpm consistantly. Can't imagine trying to take off from traffic lights and navigating NYC w/the gearing in your post. Like others have suggested try putting a 17, 18 or 19t cog w/t 48. Makes much more sense for your environment and terrain.
