ROCKBROS Bike/Bicycle Phone Front Frame Bag, Waterproof, Tube Bag,Cycling Pouch, Bike Accessories for Men Compatible Phone Under 6.5”

Fits my 30 year old bike perfectly!
After 40+ mile of use I can give an informed opinion now. In no particular order…-I have a 30+ year old bike and needed something universal fitting that complimented my 30+ year old tail bag (is it a law that everything needs to have “extreme” styling now that makes it look like it came off an alien spaceship?). This bag has no flashy decorations, no pinstripes, no skulls, nothing except reflective piping. Even the logo is muted. Perfect!-The two Velcro straps on the bottom grip my top bar securely and stays centered by the Velcro strap on the fork well. The straps have a generous length and I found I needed to cut them. If you do, cut them long enough so that the end is tucked away between the frame and the bag, to prevent unrolling. The bag sometimes shifts due to the load creating an off-center balance but not my much, maybe a half inch or so. Big whoop.-The top bag’s touch screen membrane on the upper flap is definitely smartphone friendly. I have an older Galaxy S5 in a case so if it works for my phone it will work with yours. The flap has attached adjustable Velcro halves that close snugly around whatever you put there, so you can put anything you want there from a smartphone to a solar charger. Yes, even solar chargers work inside it. This bag is renewable energy compatible!-The rear of the bag has a tiny self sealing slit for earphone cables which to me is unnecessary. It’s the 21st century, people. Use Bluetooth earbuds (keep one ear free for situational awareness, though). In case you wanted to know, Bluetooth gadgets work perfectly fine in this bag. Keep them charged with a solar charger mounted on the top, and when charged, swap it out with a smartphone loaded with music. But, that’s just how I ride.-As I pedal, my knees can and will occasionally bump up against the bag. This is a trivial thing and is easily overlooked when you’re on the trail. The bag only creates maybe two inches of girth on either side but the luggage carrying capability more than makes up for it.-On my rides I am able to fit EVERYTHING in my pockets- cell phone, keys, wallet, change, pocket knife, solar charger and Bluetooth earbuds- into this bag so that I don’t have gear banging around in my pockets while I pedal. When I put the bike away it stores my riding gloves so I’ll always know where they are. One glove or the other always seems to wander off somewhere when I’m not looking.-From the pics the bag looks like it’s just a thin plastic box, but inside the box it has soft padded lining to cushion any impact. It won’t protect the contents from a hammer, but it will cushion the fall should you accidentally drop the bike.-With the bag mounted I can no longer use the strap on my bike carrier to strap the bike’s front section down. I find I need to thread the carrier’s strap in between the bag and the frame, but the bag is flexible enough to allow it.-When the bag is stuffed full the zippers can be difficult to close sometimes. That has more to do with the bag being distorted from being over stuffed than any problem with the zipper. Readjust the bag contents and the problem goes away.-Much has been said about the bag’s waterproof-ness by others. I can’t comment on that since I don’t ride in downpours, but I can definitely say it is a lot more water resistant than any bag made of woven material (like my 30+ year old tail bag) because it’s a solid panel. I don’t care what the advertisements say about a product being waterproof- if it’s a woven fabric, if you leave it out in the rain it will eventually leak. If you typically ride in the rain, 90% of bags won’t be for you, including this one. Get an Otter box instead.All in all a great little bag that fits my loyal 30+ year old stallion perfectly. There may be more expensive bags out there but that doesn’t mean it will be a better bag than this one. At this price you won’t feel too bad about swapping it out if you do find a better bag later.

Works great, but my bike frame is huge
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.

Pretty good for E Ride Pro SR e-bike
Bought for E Ride Pro SR e-bike. Unfortunately the lower strap was just a bit too short and the neck strap was also too short. The neck strap was not really needed so i cut it off and used it to extend the lower strap. It was a bit frustrating but it worked out. The size is perfect. 5 stars if the top and lower straps are longer.

Rain proof
I like it for its simple and the pocket holds my speaker so I can jam on the go

固定用のマジックテープですが前後の長さが倍近く違い残念ながら加工せざるを得なかった。現在はほぼマグネットで固定してますがフレームがアルミなのでステンレスをフレームに加えてます。マジックテープは1番前と２番目のみしっかりした作りなので何故３番目だけ２番目の半分の長さなのか意味不明です。改良の必要性ありですね。メーカーさん頼みますよガチにw

Like: Useful and waterproof. Easy to fit on my bike.
