It’s all about the bike in New York City on the weekend of April 28 and 29 from 10 a.m. to 7 p.m. at Manhattan Media’s bike-tastic event, The 2012 New Amsterdam Bicycle Show: Benefiting Transportation Alternatives. In its second year, this event returns, bigger, better and “bikier” to Soho’s chic and bike-friendly venue, Skylight SoHo, in Manhattan.
