Two tubby tourists lie as helpless as toppled turtles after their weighty load proved too much for a pedicab, tipping it over backwards in Hell’s Kitchen.

The heavyweights, a man and woman each about 60 years old, went down for the count on busy Restaurant Row on West 46th Street between Eighth and Ninth avenues, a witness said.

An FDNY spokesman said EMS took one person to Roosevelt Hospital after the Sunday-night spill.

“I’ve seen rickshaws all over. You never think that one would tip backwards,’’ said the witness, Marc Chaykin, a Florida tourist who was dining with his son at nearby Tramonti Ristorante.

The trapped pair was comforted by a another pedi-driver as they awaited aid.

There is no official weight limit for pedicab passengers, but one driver admits he usually bypasses whale hails.

“When they’re too big, I don’t take them,” Gabarsinkh Masuri, 23, said.

“I don’t kill myself.”
