Wishbone Bikes do come with Black grips in the box, if you wish to steeze out your kids bike then here’s a great option. A great way to get one bike for the family then pass it down through the ages. For the girl get pink, and her younger brother can get new blue ones.
A trick to get the grips on the handle bars is isopropyl alcohol. pop some on the handlebars and some in the grip and the slide right on. The alcohol will evaporate away.
