Good size bag for my limited space on my EBike. Comes with a lot of Velcro to strap it to the frame

Very nice waterproof zippers, separate small compartment for small items. Fits my pump, tool set, wallet and a little room to spare. let's me still have two water bottles attached below easy to strap on.On my 2025 Specialized Diverge E5

The slim size fits my larger, 1000 ml water bottles on my XL frame. I dyed it black to match the rest of my bike - something Rock Bros should have standard, but probably compromised since they're sharing the product with Gorix.The left pocket is too narrow too be useful and I'm going to cut it out to create one, big space. Also, the piece of plastic for bottom structure should have Velcro to stick properly to the bottom of the bag, otherwise it doesn't sit flat. I'll have to fix this myself, as with so many other things we buy today. It's like buying a car online, only to find out they didn't attach the tires in order to make the price look cheaper. Some things are just standard. So much time wasted online trying to find all the flaws these companies hide.

Posting these early in case they can help someone else.Both bags from Rockbros. Both come with 5 hook and loop fasteners, (1 front, 1 rear, 3 on top) with some flexibility on exact placement. Both have a zip opening on each side - right hand side to the main compartment; left hand side to a slim pocket. Right hand side is full height, left hand side (because of how it’s bonded) is about 1/2” shorter than the bag.Both well made, look to be shower proof and both have there attachment points bonded to the main bag (not stitched).This bag (the smaller one) is sufficient for tube, basic tools, small pump and basic first aid kit. Slim side may be good for band aids, very slim lights, wipes, bandana etc. - that side is not large enough for a smart phone. The large side is large enough for a smaller iPhone height wise - may want some sort of separation from tools.

I like a top bar bike bag. It must be fairly narrow and not wobble to much while riding. This is long enough to firmly attach front and back and keep it stabilized. Though narrow, I get all my tire repair tools and a battery powered bike pump, and a full set of bike tools.I still use a small seat back pack for the overflow. All at a reasonable price. I have not experienced a significant rain shower, so can't rate waterproof. The included straps are a bit stiff. I replaced one that I loosen to store my bike for easier use. It's probably too narrow to hold spare cycle clothing and anything else. I highly recommend this bike bag.

good size, well made, looks okay and works well enough. Large enought ot hold my very large cell phone.It has absolutely NO water resistance at all. In fact it seems to collect and hold water, but on top of that somehow the inside is waterproof so water cannot drain out... yes you read that right.As long as you do not need a water proof frame bag this is a very good bag and I would totally recommend it because it offers good value.

I looked at many frame bags to fit my small bike. I decided to try this one to carry the essentials instead of a full frame bag so I can access my water bottles. It has a large compartment on one side which fits everything you see in the photo. And a smaller slim compartment on the opposite side. The bag stays in place using all the straps. They seem substantial but haven't tested it in bad weather. And doesn't rub against my legs. I like that it can be fastened in various places. If there is a negative, I would say the straps are a bit long but better long than too short.

It’s clean looking, the zippers are hidden, 2 sides, main storage and a slim pocket. Fits on both of my bikes (only two? I’m working on that.) The Velcro straps get a little challenging to tuck in completely, but better with use. Only real complaint, I can’t fit my cell phone in the slim pocket.

Product is good quality (material, zippers, and velcro straps) and fits my road bike frame well. Can store a small pump and tools even light jacket etc. Great to use when you can avoid a backpack.

The bag hits all the marks: ample storage for wallet, keys, extra tube and more on one side of bag then other side has thinner side for tire levers or thin items. Bag fits under bar fine on size “large” (size 56-ish) Kona cross bike and does not impede access to water bottles. Bag is sturdy, is held in place firmly by the included Velcro straps and bag does not hit legs while pedaling. Tested it on long rail trail and the bag does not move around when loaded with items. Have not tested it in rain yet but it appears very water resistant and even then in any bike bag I would place wallet, etc. in plastic bag or small dry-bag. Price is right and gray color is fine even though my other bags on the bike are black. Will update review after more miles are on this bag. All around appears to be a great purchase and addition for bike travel.

I bought this kind of last minute after being talked into a crazy sunset to sun rise ride. The size has it's pros and cons. The pro is it stays in place and gives plenty of access to your bottle cages. I have a larger bag which hinders access. The con is it doesn't fit a ton. The left side pocket is very shallow and does not allow you to fit much. Maybe some gels or stash of cash. The main pocket is good for maybe a cell phone, emergency wind breaker and a little food. A full size 24oz bottle will fit in there but will not leave room for my else. It's a compromise. If you're doing bike packing, this is going to be too small. For other, less demanding uses, this could be the ticket.Bag itself looks nice, straps are simple Velcro. A nice small addition would be some little divider pockets inside so you can put cash, keys, or a credit card in there vs just putting it in the main area and hoping for the best.

Due to my frame, I wasn't sure if this frame bag would fit. I tried above the top tube first,and it was annoying as it moved around. Under the top tube is the best.I was surprised it fit so well given the tight space. Went out for a ride,and the Rockbros frame bag worked well carrying: mobile,keys,with a leatherman squirt,coin wallet,sunblock stick,hand sanitizer. The bag appears well made,and I am confident it'll handle being caught in rain whether I am riding,or it's on the bike carrier.
