Installing this on my motorcycle's handlebars was easier than I expected, the u-bolt grabbed the rail firmly without any slipping. The rubber ball has just enough give to hold my phone steady over bumpy roads.

Emma O. ★★★★★ Oct 22, 2026

The rubber ball mount feels sturdy and the stainless steel u-bolt hasn't shown any rust after a few weeks in the rain. I like that it swivels to just the right angle for my setup.

I’d been struggling to keep my phone mount steady on my thick handlebars, but this U-bolt base grabbed the 1.1-inch rail without any slipping—the rubber ball really helps absorb vibration.
