ROCKBROS Aluminum Bike Phone Mount 4.7–7.1" — Handlebar & Headset Cap, Anti‑Slip Cushions

ROCKBROS Aluminum Bike Phone Mount securely holds smartphones 4.7–7.1" on bicycle handlebars or headset caps for stable, scratch-free rides.

This lightweight aluminum bike phone holder combines corrosion-resistant construction with adjustable grips and full access to ports and buttons. Designed specifically for bicycles, it clamps to common handlebar diameters (22.2 / 25.4 / 31.8 mm) and also comes in a headset-cap variation for a lower, more integrated mounting position. Anti-slip cushion pads protect your screen and frame while the spiral length adjustment adapts to phones from roughly 2.36" to 3.54" in width.

How does this mount keep my phone secure on bumpy rides?

The mount uses a robust aluminum frame paired with anti-slip cushion pads at all four corners to prevent movement and surface damage. A spiral adjustment mechanism tightens the grip so the phone stays snug even on rough terrain.

• Four corner anti-scratch cushions reduce vibration and prevent scuffing
• Aluminum alloy body resists rust while providing a firm clamp
• Spiral length adjustment ensures a tailored fit to your phone width
• Designed specifically for bicycle use for better vibration control

Will my phone’s buttons and charger still be usable when mounted?

Yes. The holder’s design leaves key buttons and charging ports unobstructed so you can operate your device or plug in a cable without removing it from the mount. This layout supports in-ride charging and headphone connections as needed.

• Reserved cutouts for charging cable and headphone access
• Button zones are free from clamp interference for easy control
• Compatible with wired charging while mounted

Which phone sizes and handlebar diameters are compatible?

The mount fits smartphones that measure approximately 4.7 to 7.1 inches diagonally, with a width adjustment range of about 2.36" to 3.54". For handlebar attachment, it supports standard bicycle bars with diameters of 22.2 mm, 25.4 mm and 31.8 mm.

• Phone width range: ~2.36" to 3.54" (suitable for many 4.7–7.1" devices)
• Handlebar diameters supported: 22.2 mm, 25.4 mm, 31.8 mm
• Two mounting styles: handlebar clamp and headset cap mount

What are the mounting style options and when should I choose each?

You can choose between a handlebar mount for traditional, easy-access positioning or a headset cap mount for a sleeker, lower-profile setup. The headset cap option offers a more centralized view of the road and a different aesthetic, while the handlebar clamp provides quick installation and repositioning.

• Handlebar mount: fast install, adjustable angle, convenient reach
• Headset cap mount: integrated look, lower profile, stable center placement
• Both styles preserve port and button access for in-ride use

Who is this for: Cyclists who want a durable, bike-specific phone mounting solution that protects their device and keeps it usable while riding. Ideal for commuters, touring riders, and weekend cyclists who need reliable phone access for navigation, fitness apps, or staying connected without sacrificing protection or functionality.
