Best GUB Motorcycle Phone Mount — 2026 Guide
GUB sells a small lineup of aluminum-alloy claw-clamp phone mounts on Amazon, marketed for both bicycles and motorcycles. All three verified listings share the same core mechanism — a cross-shaped aluminum frame with four spring-loaded “eagle claw” arms that grip the phone directly — but differ in claw length, rotation range and price.
We checked every GUB-branded phone mount listing on Amazon and confirmed three distinct products with real review volume, verified by unique Amazon parentAsin so none of these are simply color or size variants of the same underlying listing. Below are all three: the newer “Upgraded” 360° model, the thick-case-specific variant with lengthened claws, and the original budget aluminum-alloy version.
📱 One model built for thick cases (OtterBox/Lifeproof)
💰 $13.99–$20.85 price range
Top 3 GUB Motorcycle Phone Mounts — 2026
🏆 Best Overall — Most Reviewed
GUB Aluminum Bike Phone Mount Holder (360° Rotation)
The most-reviewed GUB mount on Amazon by a wide margin, with 15,464 ratings. This “Upgraded” model has a full 6061 aluminum-alloy body and a 360° rotating cradle, so you can flip between portrait and landscape without unclamping the phone. The claw width adjusts from 50mm to 100mm, wide enough for most phones from 4.7″ to 6.8″, including current iPhone and Galaxy models. It’s also the most expensive of the three GUB mounts here.
🔄 360° rotation, no uninstall needed
📱 Fits 4.7″–6.8″ phones
⭐ 4.4★ (15,464 ratings)
✅ Pros
- 15,464 ratings — by far the highest review volume of the three
- Full 360° rotation without removing the phone from the cradle
- Wide compatibility with current large-screen phones
❌ Cons
- Most expensive GUB mount here at $20.85
- Rated slightly lower than the Thick Case Design model (4.4★ vs. 4.6★)
📱 Best for Thick Cases — OtterBox & Lifeproof Compatible
GUB Thick Case Design Bike & Motorcycle Phone Mount
Built specifically for phones in bulky cases: the four eagle-claw arms are lengthened to 18mm so they can close around OtterBox, Lifeproof and similar thick cases without straining the clamp. It’s the highest-rated of the three GUB mounts at 4.6★, though with far fewer reviews (641) than the other two. The aluminum-alloy cross frame clips onto a Φ31.8mm bar directly, or use the included spacers for 25.4mm/22.2mm bars.
📱 OtterBox / Lifeproof compatible
📏 Bar fit: 31.8/25.4/22.2mm (spacers incl.)
⭐ 4.6★ (641 ratings)
✅ Pros
- Highest star rating of the three GUB mounts (4.6★)
- Lengthened claws grip thick cases other GUB models may struggle with
- Mid-range price ($17.99), between the other two picks
❌ Cons
- Only 641 ratings — a much smaller sample than the other two mounts
- No 360° rotation feature like the Aluminum 360° model
💰 Best Budget Pick — Cheapest GUB Mount
GUB Bicycle & Motorcycle Phone Mount, Aluminum Alloy
The original, cheapest GUB mount at $13.99, and still solidly rated at 4.4★ across 1,431 reviews. It uses the same aluminum-alloy eagle-claw cross frame as the other two, adjustable from 2.17″ to 3.94″ wide, with a simple 90° flip between vertical and horizontal instead of full 360° rotation. Tool-free installation onto a Φ31.8mm or 25.4mm bar.
🔄 90° flip (vertical/horizontal)
📏 Bar fit: 31.8mm / 25.4mm
⭐ 4.4★ (1,431 ratings)
✅ Pros
- Cheapest GUB mount here at $13.99
- Solid 4.4★ rating across 1,431 reviews, a reasonable sample size
- Tool-free installation, no separate adapter needed on standard bars
❌ Cons
- Only flips 90°, no full 360° rotation like the Aluminum 360° model
- Not designed for thick cases — claws aren’t lengthened like the Thick Case model
Slim Case vs. Thick Case — How to Choose
All three GUB mounts use the same eagle-claw clamp mechanism, but the claw length differs. If your phone is bare or in a slim/standard case, the Aluminum 360° or Aluminum Alloy models clamp directly with no issue. If you run a bulky case — OtterBox, Lifeproof, or similar — the standard claws may not close all the way; the Thick Case Design model exists specifically to solve that.
📱 Slim / Standard Case
- GUB Aluminum 360° (360° rotation, most reviewed)
- GUB Aluminum Alloy (cheapest, 90° flip)
🛡️ Thick Case / OtterBox / Lifeproof
- GUB Thick Case Design (18mm lengthened claws)
Full Comparison Table
| Product | Price | Rating | Bar Compatibility | Best For |
|---|---|---|---|---|
| GUB Aluminum 360° | $20.85 | 4.4★ (15,464) | 31.8/25.4/22.2mm | Most reviewed, full rotation |
| GUB Thick Case Design | $17.99 | 4.6★ (641) | 31.8mm (+spacers) | Thick cases, OtterBox/Lifeproof |
| GUB Aluminum Alloy | $13.99 ★ Best Price | 4.4★ (1,431) | 31.8/25.4mm | Budget pick |
All three GUB mounts share the same core claw-clamp design, so the choice mostly comes down to case thickness and budget. The Aluminum 360° has the most reviews by far and adds full rotation, but it’s also the priciest. The Thick Case Design carries the highest star rating of the three, though on a much smaller review base, and it’s the only one built for OtterBox/Lifeproof-style cases. The Aluminum Alloy is the cheapest and still holds a solid 4.4★ across 1,431 reviews, making it a reasonable budget pick if you don’t need 360° rotation or thick-case clearance.
Frequently Asked Questions
What is the best overall GUB motorcycle phone mount?
The GUB Aluminum 360° (B07GKT8FBZ) is the best overall pick — it has by far the most reviews of the three (15,464), a full 6061 aluminum-alloy body, and 360° rotation. It’s also the most expensive at $20.85.
Are GUB phone mounts made for motorcycles or bicycles?
Both. GUB markets all three mounts as bicycle and motorcycle accessories. They clamp onto standard 31.8mm, 25.4mm or 22.2mm round bars, which covers most bicycle handlebars and many motorcycle handlebars and accessory bars, using included spacers to adapt to the smaller diameters.
Does GUB make a mount for thick phone cases like OtterBox?
Yes. The GUB Thick Case Design (B087JG6PB1) lengthens the four claw arms to 18mm specifically so they can close around OtterBox, Lifeproof and similar bulky cases. The other two GUB mounts use standard-length claws and are better suited to bare phones or slim cases.
What handlebar sizes do GUB mounts fit?
All three clip onto a Φ31.8mm (1.26″) bar directly. The Aluminum 360° and Thick Case Design also include spacers for 25.4mm and 22.2mm bars; the Aluminum Alloy includes a spacer for 25.4mm bars. If your bar is smaller than that, GUB notes you’ll need a separate adapter.
Do I need to remove my phone case to use a GUB mount?
No — all three grip the phone (with or without a case) directly between four spring-loaded claws, no separate case or adapter plate required. For thick cases specifically, use the Thick Case Design model rather than the two standard-claw versions.
What’s the cheapest GUB phone mount?
The GUB Aluminum Alloy (B072DSRF3J) is the cheapest of the three at $13.99, and it’s rated 4.4★ across 1,431 reviews.
Can I use a GUB mount for GPS navigation?
The Aluminum 360° model’s listing specifically mentions GPS device compatibility alongside phones, and its 360° rotation makes it easy to angle a GPS unit for visibility. All three mounts’ claw widths (2.17″–3.94″ depending on model) can also fit many handlebar GPS units, not just phones.
What’s the difference between the GUB 360° and Aluminum Alloy models?
The Aluminum 360° (B07GKT8FBZ, $20.85) adds full 360° rotation and a wider claw range (50mm–100mm) for larger modern phones, and has far more reviews (15,464 vs. 1,431). The Aluminum Alloy (B072DSRF3J, $13.99) only flips 90° between vertical and horizontal and has a narrower claw range (2.17″–3.94″), but costs $6.86 less.
