I installed on my mountain bike where the trails can be somewhat rough.

Holds my phone over some pretty rough trails, only dislike I have is that the rubber bands get in the way of the lens when trying to video when riding

I use the TruActive bike phone holder on my RAD ebike and appreciate that it has not fallen off, or moved while taking big bumps, rocky trails or any other challenging road while using the security bands.

I’d use caution, however, if riding very bumpy mountain bike trails as the phone may shift...

I added this phone holder to my new mountain bike and holds my phone very well in really bumpy trails.

Worked exactly as I expected

Customer service and fabulous marketing!!I’d recommend this and their business to all.
