Bicycle Angle Frame Triangle Bicycle Frame Bag Waterproof Bicycle Triangle Bag Bicycle Bag Under The Tube Bag Professional Bicycle Accessories Oversize

It's not the best bag ever, but for $10 it's amazing. The bag is divided into two compartments. The zipper on the left side accesses a large compartment that takes up about 90% of the bag. The zipper on the right side accesses a long and narrow document compartment that takes up about 10% of the bag. The fabric is sturdy but it is not waterproof. Also, this bag is the perfect size for mounting a surplus Bird/Lime/Xiaomi scooter battery onto a bike frame.

This bag fits my Kent fixie bike perfectly, and will provide for some much-needed storage for my shorter bike rides. The zippers seem heavy duty enough for the job, and operate smoothly. There’s actually two separate compartments, and I haven’t started stuffing them yet but I think I can get all the necessary things on board for shorter bike rides.Out of the package it was installed in less than a minute. Front to back, my fixie bike has a shorter frame size and some bikes, and it fits mine perfectly, so it should work well for mountain bikes and road bikes also. I haven’t stuffed it and used it over a period of time yet but it seems to be of good construction and good quality material.Overall, I am pleased by the price and the product.

This is very thin material, and I would not want to treat it roughly. But the bag is very large, the zippers work, and the attachment straps are good enough. I bought it to hold an ebike battery I made, that would not fit in a $30 bag. So I have zero complaints. I try to carry a lot on my ebike, and I use this bag, a seat bag, and a rear rack/basket. They all work and they all carry things I need when I need them. I don't think this bag will fail, for me, but if it did I got my money out of it.

Exactly what I needed, I can carry my wallet, conceal carry, keys. Keeps my pockets empty which I enjoy.

I'm using this to hold a ~6 lb battery on an e-bike. Perhaps more weight than this bag was intended for, but it ripped out as a soon as I hit a bump on a moderately rough ride. Bag is easy to install and remove and pretty secure when mounted, but ultimately is not very durable.Should suffice for small, light items, but carry anything heavier and it's life will short-lived.
