Women's 26" Sakura Bike (5 Colors)

Why is the red one shown with gears?

Why only a 90 day warranty? Are these new? And who would one contact if the bike falls apart within the 90 day period?

90 Day offered by Micargi (bike is New), contact for Micargi: http://micargibicycles.com/index.php?route=information/contact

And why does it have front brakes?
