BTR bike crossbar frame bike bag

I bought this for my son who absolutely loves it as it holds his phone, money and keys etc when out on his bike with his friends. It’s great because he doesn’t have to carry an extra bag with him. I would recommend this product.

Bike frame phone case

The case is way too small for my Galaxy Note 9 and I ordered a large. Unless you've sent me the wrong one? I was very disappointed. Although it came very quickly ? I don't have what I thought I would, and I can't be bothered to send it back? I'll give it to someone else, if they can use it?

BTR Bike Phone Bag

The item is very useful ue to its various compartments ,the bag is very spacious and is cable to withhold two portable charges and coins cards etc, The down side of this bag is that it does not stay in place due to the straps if you dont have a bike that has rectangular surface for it to eat on the bag won’t hold in place, as a result it falls to the sides and hits the knees as you pedal.
