    Had been looking for a big ish bag for my brompton, and after looking at so many I decided on the this bag . I made the right choice very spacious and love the bottle type pockets on the rear perfect for bottles and other stuff you need easy access too. I loved the little game of " find the rain cover " in the end had to email you lol

    Excellent bag, holds enough for a long weekend. Waterproof cover kept everything dry in heavy rain. Superb customer service from Avon Valley Cyclery.

    I had expected this bag to be larger than it is, looking at pictures on the website; somehow I had thought that it would be a bit bulky. In fact I am pleased with the design. It looks capacious enough for my needs and also looks comfortable to carry as it has a padded strap, and top handle, and the bag fits nicely on my Brompton. Well, I haven’t actually tried it out yet - it was a Christmas present and hasn’t been on an outing, but I look forward to being able to load it with my essentials. I envisage it being very handy for day-to-day items and weekend luggage, and also for longer travel when supported by extra luggage on the rear rack.

    This was delivered very quickly. It fits my 23 year old Brompton and replaces an old bag that was falling apart. This is about the same size and weight as the old one. Comes with a water resistant orangey cover.

    Sturdy and light — there is enough structure to this bag for it to stand upright on the floor when empty or full. Good reflectives, handy pockets, easy on/off the bike — a great addition to my brompton life!

    A large, quality bag tailor made for the Brompton. Avon Valley Cyclery had the bag at the lowest price.

    Good carry size but press studs a bit fiddly with one hand.

    A great bag - really well designed and built. Looked at others but none seemed to have the complete features this did. Superb price and service from AVC, really quick dispatch and excellent communications. Very happy.

    First of all I needed the bag in a hurry as I needed it to take a weeks worth of stuff to hospital for an operation. After purchasing I couid see that the bag would probably not arrive in time so I emailed Avon Valley Cyclery to explain the situation and got a very quick reply from Harry. He was a great help as he sped the process along, sorted the delivery out and as a result I received the bag very quickly . Five stars for customer service . The bag itself is good. It’s a very similar design to one I’ve had on my other Brompton for over 30 years but just that little bit better. The two rear pockets are deeper than the originals and the front pocket now has a zipper on it which makes it a lot more practical. There’s also a rain cover which there wasn’t on my very old version - not that it was ever needed. The only criticism I have it that the strap that comes over the bag to hold things in place could be adjustable to be a lot longer as, when the bag is full, it’s quite tight to pull it over the bag. What I found in the past to be useful feature of this design of this type of bag is the ability to occasionally put really tall things in the bag, while leaving the top open. A longer adjustable strap would help in keeping those kinds of things in place. It’s not a biggie though as most people won’t be trying to move the kind of stuff I have in the past such as plant pots and even an upright hoover. The only other thing to be aware of is that with the low handlebars ( which as an aside I don’t think I like much anyway as the riding position is too far forward) the bag snags on them when it’s full. The main effect of this is to restrict how much you can turn the handlebars left and right. In other words you can’t do a full lock, which generally isn’t an issue when riding normally but is slight annoying when just walking the bike around. This doesn’t happen on my 1998 Brompton with the mid/ high handlebars so it’s just something to be aware of. I don’t like the flat handlebars having done a few rides so I’ll be changing them anyway… Overall though - great customer service ( rare these days ) and a good, if relatively pricey, product.

    We have the smaller bag which is great, but as were travelling around Austria soon got this for extra space as living out of it for a week, hopefully it will hold all I require.
