BONEBike Tie Pro Pack 1, Bike Cell Phone + Charger Mount for Stem, Scratch-Free Silicone Holder, Universal Cycling Phone + Power Bank Holder Compatible with Most Smartphones (Red - 2-in-1 Mount)

It holds the phone and battery secure but the part that rests against the stem is too short and doesn't make contact with the actual stem. I'd like to find one where that part is longer. I had one from another seller that was just for the phone and it was taller and actually made contact with the stem. This one just holds the phone flat against the handlebar and that top of the stem.

I would give 5 stars but no matter how taiight I stap it in it stills moves. It might be the weight of the phone. I got a pixel4xl not like that matters but it's still better than paying 40 to 60 dollars on a grip lock.

If you're phone is bigger than 5" Use This one! The other one is to small.

Very easy to install and move from bik to bike. Does not rotate! Mounted on stem, portrait orientation, mounted on handlebar, landscape orientation.

This is exactly what I was looking for.

flexible

Easy to transfer to another bike

Great

Great to have the battery pack attached to the phone while running the cycling navigation app. Keeps the phone from shutting down the display.Very satisfied

20000mAの重たいモバイルバッテリーを付けて走りましたが砂利道以外は、ずれる事なくバッテリーと携帯電話をホールドしてました。また、携帯電話の取付、取外しが簡単に出来るのでオススメです。耐久性については使い始めたばかりなのでわかりません。あとは、それなりの値段がするのでもう少し安ければイイなと思います。

名一杯バンドを締めてもスマホ自体の固定がゆるゆるガバガバで傾くし飛んで行きそう。所詮ゴムなので揺れるし、まるで安定感がない。あとついでに余ったバンドが飛び出て邪魔。

固定、取外しともに簡単。
