KEMIMOTO Magnetic Motorcycle Tank Bag Phone Case — Water-Resistant, 6.3" Fit, 8-Magnet Mount

Designed for riders who need a reliable, easy-to-use phone mount and small-storage solution, this tank bag combines a breathable triangular support, an external touch-sensitive window, and eight built-in magnets for a firm hold on iron fuel tanks. It adds a protective PVC layer at magnet points to minimize surface marks and uses a mesh-backed pocket to keep your device ventilated during longer rides.

How does this tank bag keep my phone cool and secure while riding?

The bag’s triangular internal frame holds your phone slightly away from the tank surface, encouraging airflow and reducing heat buildup. A bottom mesh ventilation panel further helps dissipate heat. Together they limit contact and provide steady, secure support so your device doesn’t sit flat against hot metal.

• Triangular support structure prevents direct tank contact.
• Mesh ventilation on the bottom improves airflow.
• PVC layer under magnets reduces risk of tank scratches.

Will the magnetic system keep my phone attached on rough roads?

This holder uses eight magnets arranged to deliver strong magnetic attraction to ferrous (iron) fuel tanks. It stays affixed over bumps and vibrations common to sportbikes, cruisers, and similar motorcycles; however, magnetic strength is reduced on aluminum tanks and won’t attach to plastic tanks.

• 8 powerful magnets for stable attachment on iron tanks.
• Works well on Sportster, sportbikes, cruisers, and street bikes.
• Not recommended for plastic or non-ferrous tank surfaces.

Can I use my phone through the window and change viewing angles?

The front panel is made from flexible TPU with a clear, sensitive touch surface that lets you operate many smartphones without removing them. The bag’s mount allows angle adjustment for better visibility, but the back mesh is not fully waterproof so avoid repositioning or exposure in heavy rain.

• TPU window supports touch control and protects screen from debris.
• Adjustable viewing angle for comfortable navigation and sightlines.
• Avoid adjusting or exposing to heavy rain; not fully waterproof at the back mesh.

What phone sizes fit, and what should I check before buying?

The interior pocket measures approximately 195mm × 125mm × 30mm and fits phones up to about 6.3 inches. For best results, remove bulky protective cases before placing phones inside and confirm your device dimensions against the bag’s internal measurements.

• Internal dimensions: 195mm long × 125mm wide × 30mm thick.
• Accepts phones up to 6.3 inches; remove thick cases for fit.
• Touch compatibility varies slightly by phone touchscreen technology.

Who this is for: Motorcyclists who want a fast, tool-free phone mount and small storage pocket that’s simple to attach to metal fuel tanks. It’s ideal for riders using smartphones for navigation, music, or quick access while on the road, provided the bike has an iron or similarly magnetic fuel tank. If you ride in heavy rain frequently or have a non-ferrous tank, consider mounts designed for those conditions instead.
