RAM MOUNTS Quick-Grip Large Phone Mount with Handlebar U-Bolt Base

In this review of the RAM MOUNTS Quick-Grip Large Phone Mount with Handlebar U-Bolt Base, the bottom line is simple: riders who need a rock-solid, adjustable phone or small tablet mounting solution for motorcycles, ATVs, UTVs or bikes will appreciate its durability and secure hold. The reviewer found the spring-loaded holder and ball-and-socket mounting system deliver reliable security even with heavy-duty cases, while the U-bolt base makes installation on handlebars straightforward and stable.

Key Features

• Spring-loaded holder: Secures larger phones and up to 9 in tablets with heavy-duty cases so devices stay in place on rough terrain.
• Interchangeable end cups: Allow you to modify the holder when upgrading to a different device without replacing the entire unit.
• Ball-and-socket adjustability: Compatible with B and C size RAM round ball bases and provides near-infinite adjustability for sightlines and orientation.
• High-strength composites: Built to withstand demanding environments and repeated use without cracking or deforming.
• Wide holder range: Height and width ranges accommodate many device sizes and thick protective cases for flexible fit.
• Lifetime warranty: Backed by a lifetime warranty for long-term reliability and peace of mind.

Who It's For

The Quick-Grip Large Phone Mount is best for motorcyclists, ATV/UTV riders, and cyclists who carry large phones or small tablets in heavy-duty cases and need a vibration-resistant, adjustable mounting solution. It suits users who prefer a modular system that can accept different end cups and integrates with standard RAM ball mounts.

Riders who want a minimal, lightweight phone cradle for very small phones or those who need a fully waterproof enclosed case should consider other mounts. Users who require windshield or dash mounting rather than handlebar attachment should also look at alternate bases compatible with the RAM system.

Pros & Cons

Pros

• Secure hold with heavy cases, reported to keep phones in place even in crashes by some users.
• Solid build quality and materials that resist vibration and harsh outdoor use.
• Flexible compatibility with B and C size round ball bases for easy positioning.
• Interchangeable end cups make future device upgrades simpler and more economical.

Cons

• Designed for larger phones and up to 9 in tablets, so it may be bulkier than necessary for very small phones.
• The handlebar U-bolt base is ideal for bars but less useful for non-handlebar mounting without purchasing a different base.
