Top Tube Bike Bag

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!

Very good quality material and easy to install and fits tight and snug on the bike. I do wish it had separate pockets inside like the other rockbros bag I bought.

Decent sized boom bag for recumbent trikes. The straps are just long enough to go around a squared boom, with ample length of strap for the front post. Secure seal on the zipper with a tuck underneath the flap when fully zipped. Easily used even with cycling gloves. Two inside mesh pockets to separate cards, tools, etc. Main compartment is large enough to hold a face mask for chilly rides, a pair of gloves, power bars, energy drink packets, electrolyte tablets, and more. One side has laced elastic cording that can hold a variety of items close at hand and away from the legs when pedaling. I lace a power cord from the lower Rock Bros. bag to a phone mount above this orange bag. Elastic cording keeps the power cable close to the back. Even have a Brook Pocket Catcher I attach to the side of the bag. Would recommend to the manufacturer to supply longer straps on front and rear areas of the bag, and perhaps offer a 4 inch longer bag of the same height and angle. Also have the elastic cording to be on both sides of this bag. Do treat the bag as have noticed fading of the material on the zipper side. Note: There is a Rock Bros Frame Bag In have underneath to boom to hold a large power pack that recharges the phone when out and about. Also carry extra tools, a cloth rag, and gloves when working on the chain when necessary. (ASIN B07QM4X22Z) I recommend both bags for use on recumbent trikes.

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.

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.

LOVE it. Held my garage door opener and a small camera. Well made. Trim to fit is nice.

I really like the design of this storage bag, you get just enough space to store the necessary items for longer bike rides. Also, it's easy on, easy off, pair it with a nice seat bag and you are good to go for storage.

Great little thing, easy to attach. Holds my iPhone 13, gels and keys. Easy to open and close without looking while riding. Recommend.

Muy funcional

Too costly still Sturdy,waterproof upto an extent,premium quality feel, aerodynamic shape to your road bike/MTB.they could have added the rotating knob instead of pulling/stretching threads to secure it to the top tube

Rock solid quality item.

Great bag very stable and stays on, fits soo much stuff and even has a little pouch on the side which I can use for snacks and tissues it also is a great size and material and I can fit my phone and thing (wallet) in the pouches built inside and also good in the rain (waterproof)
