A tricycle only has 3 wheels. I'm seeing 2 in front, 2 in rear, and if there's a wheel in back, that makes 5. Your math ain't mathing.
Every source I've seen refers to it as a tricycle. I don't know what the additional two wheels are for, but they aren't touching the ground in the pic, so I'm inclined to keep the original description.
Its for when she's in a hurry, she leans forward and really gets some elbow grease in there
