This is a smartphone holder sold as an optional part for the electric assist bicycle, velmo panorama. Purchased in October 2025, it was attached to a bicycle for about two weeks, and a smartphone was mounted on it only 2-3 times. After that, it was removed and stored indoors. By pressing the smartphone against the button in the center, the four square claws contract to hold the smartphone. It is released by squeezing the levers on the left and right. Because the button is in the center, it seems that smartphones with the thickest part in the center can be held securely. It is reported that it may not be fixed if the camera part protrudes significantly. I was using an iPhone 16 with a case that had a protruding camera part, but I was able to fix it perfectly because I was using a MagSafe ring (about 2.5mm thick). There are slight scratches on the part that attaches to the bicycle (see photo 5). For packaging reasons, it will be disassembled and shipped as shown in photo 6. ~ The product specifications from the official page are listed below ~ 【Product Description】 This product has an automatic opening and closing function with a 4-point fixing system that instantly holds the smartphone just by pressing it against the holder. Also, it is a simple and convenient smartphone holder with 360° adjustable fixing direction, and release is done by simply squeezing the release levers on both sides. 【Important Notice Before Purchase】 This product has a structure that automatically locks when the center button is pressed.
