Review: めちゃめちゃよい - これに変えてからガチで振動が少ない1！ 見た目もよくてかっこいいしマストバイです 安定感もあり良い

## Features

- 【Quick Lock & Release】- The bicycle phone mount is easy to install on the stem, allowing you to quickly attach/detach your phone in seconds with one hand. This ensures you won't miss calls or messages during cycling.
- 【Special for bicycle M6 screws】: Whether your bicycle STEM cover is round or other shapes, this phone holder can support it perfectly.The height of the aluminum alloy cylinder of the support is 8.0mm, which can be applied to the M6 screw steps of various STEM covers to avoid the suspension of the cylinder bottom and the screw steps after the mount is installed.

- 【Universal Adapters】- Our phone bike mount comes with one universal adapter, the high-viscosity industrial grade 3M double-sided adhesive tape can be strongly pasted to most cell phone cases.You can now use your phone to navigate or your Bluetooth speaker to enjoy music. Please note that Silicone / Rubber / Soft touch coatings cases are not suitable for this adapter!!!!!
- 【New Upgrade of 2nd-Gen Product】- This product has been comprehensively optimized and upgraded: 1️⃣ An alloy module has been added inside the product, making it more stable, firmer, and more durable. 2️⃣ The buckle has been increased to four alloy buckles, which buckle the adapter in four directions, and the force is more evenly distributed.
- 【Center Installation】: Conveniently installed in the middle of the bicycle stem, keeping your phone in front of you while riding. Simple installation requires removing just one screw, ensuring minimal handlebar space usage for additional riding equipment.
- 【Lightweight and Compact】:The small and mini stem mount as light as a feather, seamlessly integrates with your bike, making you completely unaware of its presence. The mount weighs only 41.5g (1.45 ounces).
- 【Perfect Viewing】- The bike stem phone mount allows you to get the perfect viewing angle and easily adjust the cellphone to horizontal or vertical screen. It is a great solution for having Google Maps visible to navigate, using a fitness app, and playing music while you ride.

- 【Rich accessory ecology and usage scenarios】The C (Circle) series mount has 1st-gen (two buckles) and 2nd-gen (four buckles) products, adapters, protective cases, silicone elastic binding adapters, and stopwatch adapters All are standardized designs and can be used in gen1/gen2 products.
