Review: Sturdy and Secure Phone Holder - This bike phone mount is a reliable and solid option for securely holding your phone while riding.

It has held up well during multiple rides, and I appreciate that it allows easy access to my phone for navigation. Definitely a great accessory for cyclists.
Review: worth the price small but mighty - I have been looking for a phone holder for my mountain bike for some time now. All the holders I have seen attached to the handlebars which I am not excited about being afraid of the mounting nut and bolts loosening after some time and forget to check before heading on a trail. I come across this phone holder that mounts to your handlebar stem. I liked the place meant and the fact that it mounts with existing bike part ( stem bolt). So, I bought it. Mounting was easy, only took two minutes making sure it was perfectly aligned. The 3m adhesive mount that you attach to the phone or case is really strong. I attached my phone to the mount and flicked the lever to lock the phone in the mount and gave it a couple of stress tests pulling and bending. After I unlocked the phone flicking the level to inspect. Not one mark no signs of stress marks or damage on the plastic holder on the phone case. The mount also showed no signs of damage or stress. I attached the phone to the holder and went for a test ride of an bumpy dirt trail. Even after all the wrenching I did to the mount, the mount and phone was still tightly secure not even a wiggle in the connection point. This is the best phone hold mount and sleekest. Definitely worth buying if this the type of mount you like and are looking for. I highly recommend this mount.

### ⭐⭐⭐⭐⭐ 2nd Gen has been a great value!
*by W***L on October 21, 2025*

I bought the 2nd Gen for 29.00. Outstanding product compared to the QuadLocks price of 90+ dollars. I’ve had this mounted on 3 different desert mountain rides which involved one very hard crash coming down hill. Moved the holder a bit, but phone was held secure. I pushed it back into place and continued on. Can’t say enough good things about this holder. Stay tight and secure and no rattling! Best 29.00 I’ve spent lately.
