Review on 🚲 VUP Bike Front Frame Bag with 360° Rotation Phone Holder for iPhone 12/Pro/Pro Max/Mini/11 Pro/XS Max/XR/X/7/8 Plus, Universal Bicycle Handlebar Bag for 4.0''~6.7'' Cellphones by Paul Wall

Can't use this on my women's small Trek Marlin 6. Maybe it would work better on a big bike? When pedaling, the sides rub against the legs. I tried to attach it to the top tube as best I could, but the straps are so long that they run out of velcro to secure the ends if you pull them far enough to free your legs. The phone holder works well and holds the phone securely even when bumped. I have an iPhone XS and it fits perfectly. This is a great sturdy bag, but in my case it's too wide to pedal comfortably.
