Adult bike riding lessons

*Cross posting from Park Slope Board

Does anyone know of any adult bike riding lessons in Brooklyn? I thought last summer I read about someone offering them in Prospect Park but so far I can't find any info. I've been promising myself I'd learn to ride some day and I ain't getting any younger....

I know that Bike New York offers a few free lessons over the summer but every single class they have is already booked out.

Thanking you all in advance!

go to Glass shop coffee, or Brooklyn Bike and Board they have people that will give lessons for free.
