Top Tube Bike Bag Narrow Slim Design Lightweight Portable | Adjustable Straps,2 Inner Net Pockets,Elastic Rope,Reflective, Compatible with iPhone 14/13/12 Pro Galaxy S22/S21,Road MTB

I bought this top tube bag to replace a bag that was too small for my new phone. I am 5'3" and my bike is a 50" frame, so I don't have a lot of extra space to work with. I was concerned at first that this bag would be too big, and in my way. The slim design alleviates that concern because I can still straddle my bike with enough room for my legs. I don't notice it on my bike at all, and it will fit my phone, wallet, and other small personal items that I don't want to put in my jersey pockets. I like the elastic attachments...fits my bike great and looks clean. I've only had it a week, so I don't know how the elastic will hold up, but it's a plus over the velcro. Hoping I will get substantial use from it.

I recently purchased the ROCKBROS top tube bike bag and couldn’t be happier with the product. It fits securely on my bike’s frame with zero wobble, even during longer rides or bumpier terrain. The material feels high-quality and weather-resistant, so I don’t worry about my phone or essentials getting wet. The best feature for me is the convenient phone compartment. It’s the perfect size to hold my iPhone and keys, without getting in the way of pedaling. For under $25, this is an incredible value. If you’re a casual rider or a more serious cyclist, this bag is a smart upgrade. Highly recommended!

I like this bag, so much I have purchased 4. My current iPhone is the 11 ProMax, and it fits (a little tight, but that’s ok) plus room for a a bar, ID/cash, keys and, currently, a mask. It’s been great, comes with LONG straps. Two complaints:1) very minor, but the knot on the side is consistently tied at the rear of the bag, and hits my right knee with each stroke. That picture I attached is an easy fix, but would be unnecessary if installed in the better (I think) position originally; and 2) the zipper is a bit funky. It stays waterproof, for the most part, and when new operates well. However, over time, especially if it sits idle, corrosion sets in and it becomes hard to operate, to the point that lube didn’t help, and on one of the bags the pull broke. I bought another bag but think this is a design flaw. The problem is accelerated because the bag sits in the “sweat zone” on the bike. (If you don’t sweat while riding, no problem.) It would be good to know the best lube to use (which oil works best without melting the plastic zipper, is silicone spray ok, should I use wax?) Also, is there a recommendation to wash it? How often? With what? I can experiment, but it would be most BROS-like I think if the company (or distributor) shared guidance and attention to detail.

The ROCKBROS Top Tube Bike Bag lives up to its promises and has proven to be a great addition to my cycling gear. One of the standout features is its perfect fit for larger phones, like the iPhone 15 Pro Max, making it a practical solution for cyclists who want to keep their phone easily accessible while riding. The bag is lightweight and portable, which doesn’t add unnecessary bulk or weight to the bike. Its new mounting system is secure, ensuring the bag stays in place even on bumpy rides. The design is sleek, and the material appears durable, holding up well against different weather conditions. Overall, this top tube bag is an excellent, straightforward solution for cyclists needing a reliable, compact storage option for their phone and other small essentials.

I’ve tried a lot of bags and nothing compares to this one. This tube bag puts everything I need within reach. It holds my phone, keys, ID, cash, snacks, and pistol. It is large enough to fit my .380, which was the main reason I purchased it. My original bag’s zipper broke kind of soon (6 months) but I liked it enough that I just ordered another. It’s been the best bag I’ve found so even if it didn’t last super long, it was worth it to get the same one. It’s water resistant, which has been nice when I’ve been caught out in the rain. All of my gear stays dry. I also appreciate that it’s very secure. No worrying about it wobbling around and scuffing your paint. My only complaint and reason for losing one star is my original bag’s zipper broke after about 6 months. It failed out on a ride, which was annoying and inconvenient, but it didn’t stop me from ordering the same bag again. Just be aware that if the zipper feels tight (you have something larger in the bag), you run the risk of the zipper pulling apart. One recommendation is trim the Velcro once you have the perfect fit on your bike. It’ll keep the straps from snagging on your bibs.

The frame storage bag works as described. Fit securely on my mountain bike and does not interfere with peddling. Quality seems good. I keep tools in a separate seat bag. The frame bag holds my phone, sunglasses and a protein bar. Not a lot of space but adequate while remaining unobtrusive.

This small top tube bag was perfect for me. That said, I have an iphone SE which is not a large phone. Bag held my phone and wallet and keys. Zipper worked fine. Straps held bag on securely. Bag nice and sturdy. So convenient having that bag right where it can be accessed so easily. Before ordering make sure your phone will fit. If the manufacturer makes a slightly larger bag I'm sure that would be good quality too.

Great bag and secured very well with the bungie strap system. I like the slimmer size which is just for my wallet, keys, and snacks while riding. The charge cable port is a great addition as well. Overall, the quality is very nice for the price.

Muy funcional

Amazing. Light weight and material feels really nice. Can easily hold my iphone 17 pro max and can easily fit 2-3 phones and your wallet and car keys.

Rock solid quality item.
