Phone holder extra digital HB390311 for bicycle, motorcycle and electric vehicle handlebars 22.2–28.6 mm

Phone holder extra digital HB390311 mounts on cylindrical handlebars with diameters from 22.2 to 28.6 mm and is intended for use on bicycles, electric scooters, motorcycles and similar vehicles. It secures a smartphone in a vertical or horizontal position and includes a security lock. The base is made of aviation-grade aluminum alloy combined with ABS and PC components for durability. The kit includes the phone holder and an adhesive adapter; the adapter uses strong industrial 3M VHB tape for a one-time quick-mount installation and is recommended to be attached to a flat, hard phone case rather than directly to the phone.

Advantages

The holder supports three handlebar diameters (22.2 mm, 25.4 mm and 28.6 mm) and offers 90° rotation for flexible device orientation. Its aviation-grade aluminum alloy base resists deformation and oxidation, and the design includes a security lock to keep the phone in place while riding. The supplied adapter and 3M VHB adhesive ensure a stable single-time attachment to a suitable case surface.

How to use

Usage recommendations

Do not attach the adhesive adapter to silicone, rubber, wood or rough-surface cases. The 3M VHB adapter is intended for one-time mounting; if removed it is not reusable—replacement adapters are available (product code HB390076). Avoid attaching the adapter directly to the phone; fix it to a compatible case instead.
