LIU HJG R8S Aluminium Bike Mobile Holder – 360° Handlebar & Mirror Mount, Without Charger

Need a simple mechanical phone mount without charging wires? The LIU HJG R8S is an adjustable mobile holder designed for compatible motorcycles, scooters, bicycles and other two-wheelers. It uses a screw-adjusted mechanical grip, a rotating ball-joint mount and two mounting options — handlebar clamp or rear-view mirror/stem bracket — so the phone can be positioned for navigation without adding a charger or electrical wiring.

This listing is specifically for the R8S non-charging mobile holder shown in the photographs. It should not be confused with HJG mobile-holder variants that incorporate USB charging, nor with dedicated vibration-damping mounts.

Product Identification

Why Choose the R8S?

The R8S is suited to riders who want a straightforward phone holder for maps, navigation and easy screen visibility without running power cables to the motorcycle. The holder is mechanically adjustable, so the phone is tightened into the cradle using the side knob rather than relying only on elastic straps or adhesive pads.

The supplied mounting hardware also gives you two practical installation choices. Use the clamp on a compatible round handlebar, or use the separate bracket where a suitable mirror/stem mounting point is available. That makes the R8S useful on motorcycles and scooters where handlebar space can vary.

Key Features

• R8S non-charging design: no USB port, power lead or electrical connection required.
• Aluminium-alloy phone support: the manufacturer packaging identifies the holder as an aluminium-alloy cycling phone support.
• Mechanical locking adjustment: side knob lets the cradle open/close around the phone for a controlled fit.
• 360° positioning: the packaging marks 360° rotation, while the rear ball-joint allows portrait/landscape and viewing-angle adjustment.
• Handlebar + mirror mounting: the kit shown includes hardware for both compatible round-handlebar and mirror/stem mounting.
• Open-face holder: designed to keep the screen visible and, where the phone layout allows, reduce obstruction of side buttons and camera area.
• No electrical installation: useful for riders who only need navigation mounting and do not want charger wiring on the bike.
• Multi-vehicle application: packaging lists motorcycles, scooters, bicycles and electric vehicles among intended applications.

R8S Without Charger – Know What You Are Buying

Handlebar Mount or Mirror Mount?

Important: “Universal” does not mean every motorcycle accepts the mount without checking. Handlebar diameter, available straight-bar length, mirror mounting arrangement, switchgear position and windscreen/console clearance can all affect installation.

Phone Compatibility

The R8S uses an adjustable mechanical cradle and is intended for a range of smartphones. However, the supplied packaging does not state a verified minimum/maximum phone width, screen size or maximum case thickness. We therefore do not publish an invented “fits all 4–7 inch phones” specification.

Before ordering, check the physical shape of your phone and case. Very thick rugged cases, wallet cases, ring holders, PopSockets or unusual camera modules can affect how securely the phone sits in any mechanical holder. The phone must sit fully inside the retaining arms before riding.

Does It Block the Camera or Buttons?

The manufacturer packaging states that the design is intended not to block cameras and common phone buttons. Because camera and button positions vary greatly between phones, final clearance depends on your particular device and case. Position the phone so that no retaining arm presses the power/volume buttons and confirm that the camera area is clear if camera access is required.

Important: This Is Not a Dedicated Vibration-Damping Mount

The R8S provides a secure mechanical phone mount, but the supplied kit does not show a separate vibration-isolation/damping module. Do not confuse normal grip pads or the ball joint with a dedicated camera-protection vibration damper.

Some smartphones use optical image stabilisation (OIS) or closed-loop autofocus hardware that can be sensitive to prolonged high-amplitude motorcycle vibration. If your phone manufacturer recommends a vibration-damping mount for motorcycle use, use an appropriate damper or choose a holder specifically designed around vibration isolation.

Compatibility / Application Guide

Before You Buy – 8 Checks

1. Need charging? If yes, do not buy this version. The R8S shown has no charger.
2. Choose your mounting point: confirm whether you will use the handlebar clamp or mirror/stem bracket.
3. Check space: make sure the holder will not touch the fuel tank, windscreen, instrument cluster or switchgear through full steering movement.
4. Check your phone with its case fitted: bulky cases and rear accessories can alter grip.
5. Check button position: ensure the retaining arms do not continuously press a side button.
6. Check camera position: especially on large camera-bump phones.
7. Consider vibration: this is not sold as a dedicated vibration-isolation system for sensitive phone cameras.
8. Retighten after installation: verify all mounting fasteners and the phone grip before riding.

• Tighten fasteners securely but do not overtighten to the point of damaging threads, bracket or handlebar finish.
• Fit the phone, tighten the side adjustment knob and physically check that the phone cannot lift out of the retaining arms.
• Turn the handlebar fully left and right before riding to check tank, windscreen and cable clearance.
• Recheck mounting tightness after the first few rides and periodically thereafter.

R8S vs Other Common Bike Phone Holders

Frequently Asked Questions

1. Is this the LIU HJG R8S?
Yes. The retail box supplied with this product is marked R8S Mobile Holder.

2. Does the R8S have a charger?
No. This is the non-charging phone holder shown in the photographs. There is no USB/Type-C charging port or electrical lead.

3. Does it need motorcycle wiring?
No. The R8S is a mechanical phone mount.

4. Can it mount on the handlebar?
Yes, a handlebar-clamp mounting assembly is supplied. Physical compatibility depends on the available bar section and clamp fit.

5. Can it mount using the rear-view mirror?
The kit shown includes a separate mirror/stem mounting bracket. Check your vehicle's mirror mounting arrangement before installation.

6. Does it rotate 360 degrees?
The packaging carries a 360° rotate marking and the holder uses a ball-joint mounting arrangement for angle adjustment.

7. Is it aluminium?
The manufacturer packaging describes the product as an “all aluminum alloy” cycling phone support. Exact alloy grade is not stated, and small mounting/fastening components may use other materials.

8. What phone size does it support?
The packaging does not provide a verified minimum/maximum phone width or screen-size range, so we do not publish an unverified size claim. Check your phone and case dimensions before ordering.

9. Will it fit a phone with a thick cover?
It may, depending on the final width/thickness and shape. Rugged cases, wallet covers, ring stands and PopSockets can reduce secure seating.

10. Will it block the phone camera?
The packaging states the design is intended not to block cameras/buttons, but final clearance depends on the phone model, camera position and how the phone is positioned in the cradle.

11. Will it fit Royal Enfield motorcycles?
It can be used where the handlebar or mirror mounting arrangement is compatible, but it is not a Royal Enfield-specific direct-fit part.

12. Will it fit KTM, Bajaj, Hero, Honda, TVS, Yamaha or Suzuki bikes?
Potentially. Fitment depends on the mounting location, not the badge on the motorcycle. Check bar/mirror arrangement first.

13. Can I use it on a scooter?
Yes where the supplied handlebar or mirror/stem mounting hardware can be installed safely. The mirror bracket can be useful on scooters with limited exposed handlebar space.

14. Can I use it on a bicycle?
The packaging lists bicycles as an application. Verify that the clamp fits securely on a suitable round bar section.

15. Is this an anti-vibration mobile holder?
It is a mechanically secure holder, but no separate dedicated vibration-damping module is supplied with the R8S shown. We therefore do not market it as a camera-isolating anti-vibration mount.

16. Is it waterproof?
There are no electronics in this non-charging version, but the supplied packaging does not provide a verified IP waterproof rating. We therefore do not claim an IP rating.

17. Is a hex key included?
Yes, the photographed kit includes a hex key for installation/adjustment.

18. Does the Under The Hood key strap come with it?
No. The strap visible in some reference photographs is not part of the R8S package.

19. Is it plug-and-play?
There is no electrical wiring, but it still requires physical installation and correct tightening on the chosen handlebar or mirror/stem mount.

20. What should I check after fitting it?
Confirm full left/right steering movement, phone retention, mounting-bolt tightness, screen visibility and clearance from the fuel tank, cables and instrument cluster before riding.
