BTR Water Resistant Frame Bike Bag And Mobile Phone Holder

Oh, and keeping the strap round the steerer tight is the key to the bag staying stable. Mine needed tightening up every now and again.

I used one of these for quite a long time with a Galaxy S3 (probably the larger size one though) which I bought from ebay.

Here are some tips:

If your phone has a light sensor to adjust the screen brightness, it may fall under the opaque part at the top with the logo. Turn off auto-brightness and set to max when you put it in the bag.

You can cut the velcro straps to length to avoide snagging things, but I advise running a sewing machine right across the cut end of the strap a couple of times to stop it fraying and the velcro coming unstitched from the strap.

Put the zips at the top near the stem to minimise knee rub when climbing standing up (it will still be there, but less annoying). (Compare 4th picture with 1st picture to see what I mean.)

If you're using the GPS, find out where the antenna in your phone is. On the S3, it's the top right, so I put the zips at the top left corner to reduce metal near the antenna for best reception.

Your top tube will eventually get quite scratched up. A piece of sticky back plastic along it would stop this I think and should be removable eventually.

Top tube mounted bags hit your legs!

Even if they're narrow enough, they mean you have to look too far down, in my experience.

My current solution is a Lidl "Topmove" stem mounted phone case. Properly waterproof and in the right position!

I got the 5 bucks version from ebay (which is exactly that model, mind you) and its a nice little bag indeed. Screen works perfectly behind that plastic cover, theres plenty of space too. The phone is well protected there.

I like it for adventure riding, using the phone as gps with an extra battery pack inside the bag. (and a few other things since the bag is very spacious).

I wouldnt use it for audio/headphones tho, its not the best place for that, id rather have audio in a backpack or something on my person (or wireless.. which is what i do, in fact).

Theres a couple issues with that bag:

- the zipper handles are noisy while riding and it annoys me. So i cut their handles and put some paracord. No more noise.
- the straps arent the best and on some bikes theyre harder to correct put than others. Generally the plastic rectangle will go sideways which isnt exactly nice.. but still works.

For the price, its hard to beat. this bag.

I got one of these so I could use my phone as a satnav on my road bike and hybrid. It rubbed against my knees on the road bike but not on the hybrid. Its OK in the rain and is useful storage. The downside for me was that when it's sunny the glare from the cover prevents me seeing the phone screen. The touch screen works faultlessly though. My solution to a decent navigation device was to buy a garmin edge 200 and load it with gpx tracks

I use one (well a £5 equivalent ebay bargain) along with with my JandD frame bag on my mtb and road bike.
Works perfectly for a cheap out-of-the way mount for the old phone I use as a GPS. Much safer than on the handlbar.
Handy place to store backup batteries and the Kemo USB connector for dynamo power.

Used it on the LEL last year and it didn't fail once.

I've owned loads of these now (damn deal extreme for selling them so cheaply!) and this is the best I've had so far:

It sits on your top tube/handlebars so there's no danger of knee chaffage, and it doesn't slide around your top tube like a dead sloth when you knock it.

Tote bags? Shudder....

I don't even mount a pump on the bike - let alone deface it with zip bags.

Oh, yet another re-branded bag from Dealextreme? How sweet!

It looks interesting to me as my bike frame is so small(13 inch) i cannot use one under the saddle.
I have a mountain bike frame to top tube slopes, i shouldnt think it would be aproblem.
On the website it comes in 3 sizes...which size is the one tested? Would be handy to know, especially as you describe the amount of contents it will take.

I've never had that problem with my Topeak tri bag although I'd imagine you might with this one as like you said it's much wider. A great idea thou to integrate the phone pocket.

I've tried bags in this position but they chafe against the inside of your thighs whenever you pedal out of the saddle. Very(!) irritating on a tough climb and the velcro fasteners can end up making a mess of your bib shorts. This one looks wider than most so the problem would only be greater.

It's a shame as I would find regular eating on longer rides a lot easier if the food was there in front of me. I guess they're good for flatter rides where you're not going to be out of the saddle.
