Fashion fixture Lorenzo Martone is making bikes with the same clean lines and styling as a tailored suit. The fashion publicist and advertising executive celebrated the launch of Martone Cycling, his line of men’s and women’s street bikes, at the Paramount Hotel in Midtown the other night. Friends including Marc Jacobs, Nate Berkus, Jeremiah Brent, shoe designers Brian Atwood and Alejandro Ingelmo, Peter Som, Simon Huck and Jonathan Cheban came to the bash to support him, while Vie Luxe International CEO Marjorie Gubelmann, who’s been DJ’ing parties recently as “Mad Marj,” manned the turntables. Martone will today host a launch event at Surf Lodge in Montauk.
