Serena Williams and her husband are worth nearly $200 million, but they still opt for the simplest form of mass transit in NYC -- a dude on a bicycle.
Serena spent part of Saturday, her off-day from the U.S. Open, cruising in a pedicab with hubby Alexis Ohanian and their daughter, Alexis. Talk about pressure on the pedicab rider -- just weaving through crazy city traffic with the G.O.A.T. of tennis hitched to you!
The fam was most likely having an early celebration their little girl's birthday ... she turns 2 on Sunday, but Mom's gonna be busy playing Petra Martic for a spot in the quarterfinals.
