BOBO BM4 PRO Jaw-Grip Bike Phone Holder — with Vibration Controller

A phone mount that holds your phone tight is only half the job. The other half is what constant engine buzz and road vibration do to your phone's camera and internals over months of riding — and that's the problem the BM4 PRO is actually built to solve.

It starts with the same jaw-grip system as the standard BM4: spring-loaded arms that lock your phone from the sides via a side knob, keeping every button and port free. What sets the PRO apart is the vibration controller built into the mount itself — it absorbs road buzz before it reaches your phone, instead of transmitting every bump straight from the handlebar to your device. On long rides, that's the difference between a phone that's just held in place and one that's actually protected.

It fits phones from 4.0 to 7.0 inches and installs the same way as the standard BM4 — compatible with most handlebars and scooters, no special tools or permanent modification needed.

For riders who use their phone hard. If you're running navigation for hours at a stretch, or your bike has a buzzier engine at speed, the vibration controller is the upgrade that protects the phone doing all that work — not just holds it.

Backed by a 1-year replacement warranty.
