Staff from Sheffield's Jessop Wing maternity unit sported 1950s and 60s midwife outfits for the four-mile ride.
Money raised will go towards three new birthing pool suites.
Senior midwife Amanda Muller, who organised the event to coincide with International Day of the Midwife, said it was a "spectacle".
"Eighty midwives, the majority of us aren't cyclists, on bikes, in costume... I never thought for one minute it would generate this much interest but it's been amazing," Ms Muller said.
