Is there anywhere I can charge an e-bike in the javits center or around the javits center

They have a Citi Bike station but I am not sure if you can actually charge your specific ebike. But then again, it's the Javitz, they may very well have designated areas I just never noticed them and I was just there on the 6th.

I don't think so

I am not sure, because I have not been there for a while.

Thanks to the people who answered the questions I only took notice that they were e-bike in the front.

Yes in front of the building you can see Citi bike station

In front of the building there is a Citi bike station.

In sure There should be places to lock up your bike I know they have city bikes in the area as well
