RAM Mounts X-Grip Large Phone Mount with Handlebar U-Bolt Base

In this review the RAM Mounts X-Grip Large Phone Mount with Handlebar U-Bolt Base is evaluated for riders who need a secure, adjustable solution for large phones on motorcycles, ATVs, UTVs and bikes. The single biggest reason to buy is the spring-loaded X design paired with a U-bolt base and medium B-size arm, which together deliver a reliably tight hold and rugged adjustability without covering the phone screen. This mount is aimed at users who expect durability and real-world stability during spirited or off-road rides.

Key Features

• Spring-loaded X design: Holds large phones firmly while keeping the screen and ports visible for navigation or music control.
• Optional device tether: Adds peace of mind during rough trails or heavy vibration by providing a secondary safeguard against drops.
• U-bolt base: Fits rails from.5 in to 1.25 in in diameter so it installs on most motorcycle and bicycle handlebars without adapters.
• Medium B-size double socket arm: Ball-and-socket adjustability lets riders position the phone at nearly any angle for glare-free viewing.
• Marine-grade construction: Powder-coated aluminum, stainless steel components, and high-strength composite resist corrosion and maintain stiffness under load.
• Lifetime warranty: Manufacturer backing provides long-term confidence in the mount's reliability for regular use.

Who It's For

The RAM X-Grip Large Phone Mount is best for motorcyclists, ATV/UTV riders and cyclists who carry larger phones and need a visible, secure mount that can withstand vibration and the elements. Riders who use turn-by-turn navigation or want quick thumb access to their screen will appreciate the open X grip that does not obscure the display.

It is not the right choice for users who require a fully enclosed, weatherproof phone case or those who need an ultra-compact clamp for tiny bars under.5 in diameter. Riders wanting an integrated USB charging cradle should look for a different, powered mounting solution.

Pros & Cons

Pros

• Excellent security for large phones thanks to the spring-loaded X and rubber caps that protect the device.
• Durable materials and stainless hardware resist corrosion on exposed handlebars and in wet conditions.
• Very adjustable with the B-size double socket arm for ideal sightlines and reduced glare.
• Easy to install on common rail sizes and includes an optional tether for extra protection.

Cons

• Phone rotation feedback is mixed among users, so very frequent or smooth portrait-to-landscape swivels may require retightening for some setups.
• Not a sealed or charging dock, so it does not protect against heavy rain unless paired with a case.
