Getting a foot caught in the wheel could possibly result in injury, the U.S. Consumer Product Safety Commission said.
The cargo bikes were sold from May 2011 through December 2012 for abut $1,100 each.
They came in orange, black or blue, with the word "Mundo" on the top tube of the frame. The word "Yuba" is on the vertical tube.
Consumers were advised to stop using the recalled bicycles and contact Yuba Bicycles for free wheel covers or wheel skirts and have them installed at no cost.
Consumers can call 877-889-9822 for information.
