Question: what are the bag's dimensions?
Document: I searched this site for some dimensions before I bought it and all it specifies is 91 cu. inches...which is a bit hard to visualize. What do people manage to put in this? It's about the size of a paperback book, so I guess you could do that, but forget about a wallet and a cellphone in addition. There's a tiny pocket on the side that seems like it might hold a leatherman tool or hex-key set, but nothing else.
I don't want to know the cubic inches, but the dimensions of the item to know if it will fit on my son's bike. External Dimensions: 8"wide x 3"deep x 6"high. And yes, it fit my son's 14" bike very nicely. The bottom strap had to be wrapped around the head tube more than once, to get it tight enough, as another reviewer mentioned (thank you for the idea). It doesn't sag like other children't bike bags do.
I acquired a used Dahon Jack D7 recently. I grew tired of carrying everything on my person and found this bag. I am able to put a multi-tool, tire removal tool, phone, license, and 3 levers with plenty of room to spare. The handlebar's paint is obviously worn, but the bag covers the spots perfectly. The bag's stripe is a perfect replacement for the missing front reflector (although some of my neighbors don't believe in turning on headlights at night).
works fine
very nice for the handlebar to keep the important items in. Is a little small, especially on the end since most cell phones are getting larger. plenty of ways to secure to bike and nice shoulder strap to use after removing. Overall I recommend for all cycling ventures....
mini bag lots of room inside for all your stuff key,cell phone , easy on easy off does not get in the way of your hands
Yes, I used it a lot and frequently, but ripping after a week? Not good. They replaced it and gave me a new one and I don't use this for my regular commuting, but I assume it will also rip as soon as I put it to consistent use. It is smaller than it appears and those side pockets are useless for a phone--they are teeny tiny! Literally, good for your chapstick or maybe a CO2 cartridge, but that's about it.
Works for me as I didn't want anything too large (or too small). Easy to remove. Buckles securely. Fits my small frame road bike. Just large enough to hold the things I want with me on a ride. Anything smaller would be too small, larger wouldn't fit my bike as well.
When my shipment came in, it did not have the shoulder strap, which wasn't that big of a deal, but I sent it back for a refund instead of a replacement because it just wasn't big enough for what I wanted to use it for (iPod, Nexus 7 tablet, wallet, phone, other random things).The quality of the bag seemed fine, but the plastic part on the top is REALLY shiny, so be warned
What you need to do is to show some flexibility in mounting. My first thought was this bag would be in front of the stem / bars but there it interfered with my cables. This at first discouraged me but a bit of thought and I reversed the mounting to it is behind the bars and stem. There it's quite secure and very easy for me to access at traffic lights should I wish to get something from inside there. If it were leading the bars, I couldn't get at it nearly as easily.
Answer: yes
