Not too big but big enough to put the b twin small u lock a few snacks and a waterproof cycling jacket in with a bit of space to spare very happy with product

I’ve had this bag for a few years and used it on various road bikes.....one slight downside is that it droops downward if full, but don’t let that put you off, it is a really versatile bag, I puts lots of items in it, like camera, mini tripod, keys, phone, base layer etc and the Velcro straps are strong and reliable......which also makes it easy to remove to take into the cafe

Didn't fit on women’s MTb bike very well so returned it.

Easily fits mini pump, bottle of drink, a snack, phone, light windproof top, keys, phone, coin purse, a few tools. Easy to fit to bike, zip keeps everything secure and in easy reach. I thought my cycle buddy would like one too and I wasn't wrong.

Bought this recently ready for a long ride, the straps held it in place securely and there was no fouling of the cables. Would recommend for occasional use.

Not too big but idea for mobile phone, battery pack, snacks etc and rain jacket. Easily secured to the bars with two wrap round Velcro straps. Slightly droops down and rests on gear cables. Excellent value for money product.

looks good easy to install and remove

Bought so had somewhere to put stuff on mountain bike; phone, keys, maps, water, snacks. Fixes to handlebars for easy access whilst riding.

For the low price this is a useful little bar bag. It is fixed to the handlebars with two Velcro straps making it easy to remove and take with you into cafes etc. The downside is that it flops down as there's nothing except my brake cables to hold it up, but, if you use it for lightweight items it works fine.

Actually using this bag on the inside of my pannier rack on my motorbike to enable water storage.

Daughter is very happy to have it on her bike.

good size
