Jeff Underwood the owner of Continuum Cycles on Avenue B between 12th and 13th Street opened shop about 7 years ago.
Now there is also a recent addition of a cafe next door ( serious coffee my friends....) and who knows what's next.
He has his own line of bikes and if you are interested about the details, just check his website.
But they also repair any old bike and are super nice and welcoming, no snobbery ever.
I just loved to hang out in here, reminds me of my Grandpa who had a bicycle shop in Germany.......
