ROCKBROS Bike/Bicycle Phone Front Frame Bag, Waterproof, Tube Bag,Cycling Pouch, Bike Accessories for Men Compatible Phone Under 7”

Works great. Plenty of room. You can see, adjust the phone while in bag. I use it every time I ride.

This is exactly what I was looking for: The phone is velcroed securely into a pocket that makes it visible through the plastic window, the storage area is big, it's a really useful thing to have and secures well to the handlebar post and the frame.My bike, however, is an Aventon, and the battery is inside the frame, so the frame is HUGE and the front Velcro strap, although long (as they all are) doesn't fit around the frame. The other two do and that keeps it secured well enough, and I just fasten the loose strap back on itself. This would work great on any other bike, but if you have an Aventon or any other bike that stores the battery inside the frame, this may not fit. It still works fine, but if the front Velcro strap were longer, it would be nice.

Got this mostly to get my phone out of my back pocket and potentially where I could see it through the transparent window. FWIW said window is also, in part, a green house so phone gets a little warm on prolonged direct sun. Bag is large enough for iphone 13 pro, but not for my predecessor Samsung AOS2 which oddly is 2cm longer than the iphone and slightly wider. The straps hold the bag with phone pretty well immobilized, but it does shift a little bit if bumped. Bag is wide enough that I occasionally touch it with my knee while riding, but this is ok. Main annoyance is when I stop and get off the saddle to put foot on ground the bag pokes my front as the saddle pokes my rear, not much space in there. Bike is a 54cm.Never the less I am keeping the bags as I think they are a better solution than carrying the phone in my back pocket, especially when it cools off and multiple layers will bury the pocket. Just measured and one bike has 8" from saddle nose to bag, the other only 7". Not the best but tolerable as I spend 99% of my time on the bikes riding and not standing around. FWIW the bags come with lime green elastic edge water proof covers which just fit over the tops of the bags presumably to keep contents dry in heavy rain. The bags seem well built and likely to hold up for years. One final comment, there is a double zipper and since the space is constricted running the zipper around the end towards the saddle while standing straddling the top tube is a little touchy. I weigh ~140#, so those more amply endowed and short will have to get off the bike.Further experience: getting used to the small distance between saddle nose and back of bag. Have also noticed that while riding, if I stand up to eg go faster up a hill, my knees will hit the bag every 2d or 3d pedal stroke, so makes standing while pedaling less comfortable. But again I rarely stand and can get used to not doing, compared with the advantage of having the cell phone more accessible.

Nice bag very well made

Well made, has plenty of velcro in case your bike is wide, made it perfect for my ebike. It feels high quality and well designed, installing it took under 5 minutes, it was very easy to take on and off. The touch screen is very easy to use and the plastic is very clear. It fits my phone with its case, and even with a privacy screen it's very easy to see my screen while I bike. The zipper also feels secure so I'm not worried about anything falling out. I biked with it this morning and it was great!

This phone case works great. It is a great design.I have a Samsung Galaxy S24 Ultra with a Otterbox case, and my phone fits perfectly in the window. The touchscreen works great thru the plastic cover that zips up around your phone. It has a nice size compartment just under you phone. Enough room for your keys, wallet maybe a protein bar. It mounts easily and holds your phone as well as your other goodies very securely. I ride a mountain bike on moderate trails and it stays in place just fine. The only issue I have is, where it had to be placed on my bike made it difficult to see. Now, this may be due to my bike design and not the product design. I need to be able to glance at my phone and not take my eyes off of the trail for more than a second. I really do not want to have to see if my helmet will adequately protect my noggin if I crash into a tree because I had to take my eyes off of the trail to check my GPS in order to follow the desired route. That being said, if this case will fit on your bike in a place where it is fully visible, it is a great choice.
