Review on 🚲 Trkimal Bike Phone Mount: 360° Rotatable Silicone Holder for Cycling GPS, Fits iPhone X XR 12 11 8/8 Plus, S20 S10+ - Universal Handlebar Mount 20-46mm by Robert Hole

The silicone straps don't inspire confidence, but I've ridden them enough to know, at least for a short term, that's a solid $5 -Deal. Works well and is identical to some others for more than double the price. The detachable feature is redundant as detaching the phone from the silicone straps is as easy as detaching the phone mount from the stem mount. When attaching the phone to the straps, be sure to stretch the straps to equalize the tension after the phone is inserted.
