Great value

I wanted this bag for a folding bike that I use only occasionally and did not want to pay twice the price for something from the big makers. I am very pleased. As supplied it will stand up to a heavy shower. It makes sense to charge extra for a completely waterproof covering. I do not need one and I am happy not to pay for one. The bag is well made. I particularly like the strong zips. It is thought out with a good sized luggage space and easy access side panels as well as a net on top. It is surprising how much it will take but it is made from a rather stiff fabric and I think that "stuffing" it would easily strain the seams, If I use it properly I expect it to last for a long time. Most importantly it fits easily but securely to the rack. My only "******" is that there is a tab for the rear light on only one end of the bag. It suits my rack to mount it backwards. A tab at each end would be an improvement. Overall I think that I have a thoroughly workmanlike (workpersonlike?) product at a good price. It is ideal for occasional use and I would expect it to be at least satisfactory in daily use.

Perfect cycle bag

The bag fits perfectly over the rear pannier. Good secure fit. Very roomy, can take camera water bottle keys and sweater. Good zipped side pockets that easily fit phones or walkers. Very happy with the purchase.
