Also kept everything dry in downpour. **Q: When I put my bike on my car bike rack will I need to remove the bag to put the straps over the cross bar?** A: Yes you will have to remove any bar bags as they will interfere with most racks for mounting. You can always get around this by moving the bag to a different part of the bike but then you have to affix it back when riding for functionality. **Q: I have the iphone 11 pro max, can i use this case to store this phone?** A: I have the iPhone X and it just fits. Based on what I now of your Phone, it is going to be close, maybe too close. I would look elswhere **Q: Would the medium bag be too large for a child’s mountain bike?** A: Childs department store bike with buzzliteyear on itn? No. Youth mountain bike? Yes. Should work just fine. Prolly make some kid real happy and turn them into a pro bikepacker. After all thats the key to adventure.

Holds a lot for such a compact bag. It's well made, legitimately waterproof, durable and easy to clean. ### ⭐⭐⭐⭐⭐ Very functional & perfect amount of room *by E***M on February 21, 2026* Was using under seat bags, which would not hold enough stuff including my phone. Also under seat bags tore my cycling pants a couple of times. This bag is great, probably not as aerodynamic but I will take functionality. ### ⭐⭐⭐⭐ Nice and waterproof *by J***G on June 11, 2026* Held up great to 3500 mile of bikepacking. Waterproofing is on point. Can just slip in an average battery bank and some snacks. It can kinda slip around on the top tube unless you put something grippier down around the tube. The only issue is that it’s really quite difficult to close unless you stop and use two hands. just collapses on itself. But not a dealbreaker in my eyes. ## Frequently Bought Together - ROCKBROS Bike Top Tube Bag Bicycle Front Frame Bag Waterproof Bike Pouch Pack/Phone Bag Cycling Accessories Pouch for Mountain Road Bike Medium - ROCKBROS Bike Seat Bag, Bicycle Saddle Bag Under Seat 3D Shell Cycling Seat Pack for Mountain Road Bikes Black - WOTOW Bike Repair Tool Kit, 16 in 1 Bicycle Multitool with Tire Levers Hex Spoke Wrench, Multi Function Accessories Set for Road Mountain Bikes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/63921397-top-tube-bike-100-waterproof-bag-bicycle-front-frame-bag](https://www.desertcart.hr/products/63921397-top-tube-bike-100-waterproof-bag-bicycle-front-frame-bag) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-09*
