I used it twice on some light gravel rides, but shelved it because the phone was just too big to have on my MTB bars. It collected dust for about 8months.Today however I set the mount on my road bike and the phone fell out of the mount twice. So after a total of 4 rides, the connections completely failed. No bumps honestly just road vibrations. Totally weird and extremely disappointing. Both times ensured phone was locked in and lock was in the set position after the phone came off.I even upgraded to the bettor version of this thing.I think your better off spending the $15-20 on the quad lock. This is a complete waste of $30. ### ⭐⭐⭐⭐⭐ Works well *by on Reviewed in the United States January 16, 2023* Took a little modification, but I managed to fit it onto my motorcycle's handle bar clamp. I imagine using it as intended would make installation easier. It lasted the 760 mile trip to Florida, and made it another 760 miles back home without any issue. I did have it behind the wind shield though, so I don't know how well it would hold up to highway wind speeds. ## Frequently Bought Together - sincetop Bike Phone Mount,Mountain Bicycle Stem Cap Phone Holder,Universal Aluminum Handlebar Phone Clamp,MTB Road Bike Cycling Mobile Phone Clip,Quick Attach/Release 【Series C-2nd Gen】 - CamelBak Podium Chill Insulated Bike Water Bottle - Easy Squeeze Bottle - Fits Most Bike Cages - 21oz, Black - CamelBak Podium Steel Insulated Stainless Steel Bike Water Bottle – for Cycling, Fitness & Sports- Fits Most Bike Cages, 22oz - Moss --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/406164419-bike-phone-mount-mountain-bicycle-stem-cap-phone-holder-universal](https://www.desertcart.tn/products/406164419-bike-phone-mount-mountain-bicycle-stem-cap-phone-holder-universal) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-01*
