MOOCi Triangle Bicycle Frame Bag - Waterproof Under Tube Bag - Professional Accessory

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.

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 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.

I like it has two divided pockets with zippers on either side. Holds my cell phone, bike tools, wallet, house keys, pen and paper. Fits by hanging nicely out of the way under the top bike bar. Slim design and quality made, quality materials. Great price! You won't be disappointed. First measure your bike to see if it fits. It fits mine perfect. Don't know if it fits a woman's bike, Not sure.

I picked this up to hold a battery for my e-bike based on it's dimensions. The bag was a bit bigger than the battery so I figured no problem. However the only entry into the main compartment is a zipper along the side. So while you have a nice large storeage area, you can't fit a solid similarly sized object inside. Other than that I found the bag easy to install, and it has a smaller pocket on the other side which is useful.

Is a good size with 2 separate compartments, and the velcro straps are nice. I wish it had a solution to secure the front of the bag to minimize the side to side movement but it's not really that bad over all. I wouldn't bank on it being waterproof but maybe water resistant for a short amount of time before it soaks through the fabric. The model pictured is my 1997 specialized hardrock 🤣

Got my new bike bag today, and it’s already proving to be a great pick. My last one held up for several years, even with how rough I was on it, so I had high expectations. This one fits my bike perfectly and holds just enough for those everyday rides—tools, snacks, phone, you name it.

The bag arrived in excellent time. The bag was exactly as described. It is a great bag. It’s very durable. It’s perfect for what it’s made for. Unfortunately my mistake in ordering the bag. I just didn’t need it. However the next bike I build I will be able to use it and I’ll re-order it. Thank you to the company for the very fast refund, the buying experience was great and I’ll be back to purchase again.
