Back in the Big Apple after spending time visiting her hometown of Toledo, Ohio, Katie Holmes took 6-year-old Suri Cruise out on Saturday (August 180 for what's a milestone moment in every young child's life.

Going casual in a simple white t-shirt and jeans look, the newly single ex of Tom Cruise and her pink helmet donning daughter took to a West Side Highway pathway for a bicycle riding training session.

The too-cute twosome provided for quite the adorable site as Katie gently propped and pushed her pink bike pedaling princess while giving a few pointers along the way.

The mother/daughter moment comes as Suri is just weeks away from kicking off her formal education at an exclusive new private school in Chelsea named Avenues.

With the learning set to get underway just after Labor Day, a recent report tells that both Katie and Tom will take part in dropping their little girl off on her first day, as an insider told Radar Online, "It's a big moment in Suri's life and Katie wants Tom to be a part of that."
