Product information

Description

extra digital HB390045 is a stem-mount phone holder designed for bicycles and motorcycles. The compact black holder attaches to the handlebar or stem and secures a smartphone in vertical or horizontal orientation. Constructed from aviation-grade aluminum alloy and PC components, it offers a lightweight yet durable solution for using navigation, fitness apps and calls while riding. The set includes the phone holder, adhesive adapter and M8 screw; a 24-month warranty applies.

Advantages

The holder base is made of aviation-grade aluminum alloy that resists deformation and oxidation for long-term use. It allows quick, one-time mounting with industrial 3M VHM adhesive for a strong bond to flat, hard surfaces. The phone can be fixed vertically or horizontally and the unit includes a security lock and an M8 screw for stem mounting. The design is compact and relatively light, suitable for both bicycles and motorcycles.

Bicycles (road, mountain)

How to use

Stick the supplied adapter onto a flat, hard surface of the phone case (do not attach the adapter directly to the phone). Use the M8 screw to fix the holder to the stem or handlebar hole with a 14 mm diameter. Place the phone into the holder and secure it using the integrated security lock; the device can be positioned vertically or horizontally. The adhesive adapter uses strong industrial 3M VHM adhesive for a one-time installation.

Usage recommendations

Do not attach the adhesive adapter to silicone, rubber, wooden or rough-surface cases. The adapter is not reusable after removal; a replacement adapter can be purchased separately (product code HB390076). Ensure the mounting surface is clean, dry and flat before applying the adhesive for the best bond.
