BTR Water Resistant Frame Bike Bag And Mobile Phone Holder
7 10

The BTR Water Resistant Frame Bike Bag And Mobile Phone Holder is essentially a handy little tote for change, multi-tools, keys and similar ride essentials you might want easy access to.

Made from a reassuringly rugged nylon, it's a two tier design very similar in layout to Birzman's Zyklop Voyager reviewed here back in April. The upper deck, complete with clear PVC face is designed to accommodate compact smartphones up to 10x6x1.5cm. Convenient for visual checks it isn't really conducive to sweeping and similar touch screen commands on the fly.

Your gizmo sits on a shock absorbing, medium density trap-door type insert that locks in situ via Velcro, segregating sensitive electricals from bike related essentials stowed in the hull. Down below there's enough real estate for a medium sized multi-tool, small roll-type nylon wallets, keys, tyre levers, blinkies, batteries and patch kit without feeling overburdened.

Sensible packing pretty much precludes that irksome jingle over washboard surfaces, muffled further by the flexible base that does a decent job of defending top tube paintwork from unsightly swirling or more serious damage.

Conversely, the Velcro straps felt decidedly bargain basement, with some minor fraying evident within a week's service. In fairness, this hasn't worsened and seems competent enough, readily accommodating standard and oversized tubing alike.

Fitment/removal is similarly faff-free, even in full-finger gloves. Bold retro-reflectives are another plus, offering coordinated contrast by day, boosting nocturnal safety at junctions, or when entering the flow of traffic since they're not easily obscured by rider girth, even on racier configurations.

Stitched, as opposed to welded construction coupled with basic zipper and MP3 head phone port means it could never be considered anything more than water resistant. Credit where due, it's resisted relatively heavy cloudburst for an hour and less enthusiastic, everyday stuff shouldn't pose any problems.

However, unrelenting biblical rains will eventually saturate the fibres, requiring several hours at room temperature (packed with old paper) before it's fully dry, so pack a heavy duty freezer bag on longer, Audax type outings.

Convenient to use, though my zip-tie loop trick makes the zippers more convenient on the fly/wearing full-finger gloves. Touch screen functions a little hit 'n' miss too but this seems typical of the genre.

Tell us how the product performed overall when used for its designed purpose

This little bag has been something of a pleasant surprise-smart looking, user friendly and an excellent option for smaller smart phones (Samsung Galaxy Y, older Sony Xperia etc), or even small bottles of sunscreen on hotter days. Tardis like interior caters for the usual ride essentials without catching inner thighs when honking and while not truly waterproof, ours has resisted moderate downpours commendably.However, line sensitive electricals in a freezer bag or two in case of biblical stuff.

Tell us what you particularly liked about the product

Nicely made, practical bag with pleasantly neutral styling.

Tell us what you particularly disliked about the product

Velcro straps seemed lower rent than some but hasn't marred practicality.

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.

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.

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.

Tote bags? Shudder....

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

 24 Seriously? You know that the Velominati are satirical, right?

My bike, my only bike, has a rack, hi-viz snap bands around seat-tube and head-tube, and generally has two rear lights and two front lights. And a pump. And a bottle cage.

do you sit on your bike or just push it around at the end of a long pole so as not to spoil its clean lines?

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:
http://m.dx.com/p/roswheel-11810-outdoor-cycling-pu-pvc-bicycle-handleba...

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.

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 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 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.

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 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.

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.

Hi, do you know which size bag it corresponds to...small, medium or large? Thanks. The reviewer does not say.
