Our Editor Says "This is a great crossbar bag with the longer front strap if your top & down tubes meet on the handlebar stem" 


Create extra secure, safe & dry space on your bike with our BTR Frame Bag Gen2. This bicycle frame bag has the option to purchase with a raincover which is 100% guaranteed to keep your valuables dry. 

With 3 x Straps - designed so the underneath straps fit with one around the crossbar & the other to go under the down tube, so it is ideal for styles that have them meeting together with no gap on the handlebar stem.   The hook & loop fastening ensures it fits snugly & adjusts easily.

From our BTR Bike Frame Bag Range, the Gen2 Frame Bike Bag was created for this specific style of bike frame & is a popular choice for cyclists who want their belongings in easy reach and their GPS system secure on their bike

Cross bar phone holder pouch

This product is really great. I can see my phone well and control it through the plastic window. The pouch is roomy enough for for my glasses case, phone case, blue tooth connection, spare earphones, cloth, several gels or bars. oh. and the bag cover. It stays in place during my rides, just occassionally slipping slightly to the side, (which is to be expected due to the nature of where it is!) but certainly not causing a problem. Just perfect! Thank you BTR Cheryl

Brilliant service and excellent value.

The bag is very well made and tremendous value for money. There is plenty of adjustment in the fixings ( a bit too much in the rear strap as I had too put a tuck in it to shorten it ). Holds far more than I thought and pocket for the phone is perfect.

The strap is not the best to secure to the frame, screen mists up do quickly The lead for headphones is rubbish Overall not great and I've brought a better 1

The ideal present you didn’t even know you wanted

Arrived quickly. Bought as a birthday gift this proved really popular. It is really easy to secure to the bike and eaqually easy to take off when parking your bike. The zipped pocket is large enough for all those items which usually fill your pockets. Your phone is snuggly held in place and is it easy to read through the protective cover to the screen.
