Review on 🚲 Suleto [Latest & Premium] Bike Phone Front Frame Bag, Waterproof Bicycle Phone Bag Cycling Top Tube Bag Mountain Bike Cell Phone Mount Pouch Compatible with iPhone 12 Pro 11 XR XS SE 8 Samsung S10 S9 Below 6.3 inches by Adam Martin

The top strap is a little tricky to fit around the front bar on large frame bikes, but it is certainly necessary to prevent slipping into the seat and also preventing rollover. I'm a big guy and have a big bike - it was almost too short on my beach cruiser. I ended up lengthening it by tying velcro around the A-pillar and adding it to the bag strap. My cell phone is well protected. There's a wide, padded Velcro strap that pulls my phone to the see-through protection, and enough room to toss my flimsy map case and keys behind it. The side pockets are great for chewing gum (should be saliva) and other accessories you might need.
