Nice, sturdy bag for your biking essentials.
Iâm happy with the quality of this rack bag. It has sturdy, semi-rigid sides and 4 strong, well placed Velcro tie downs to make sure it stays put on your bike rack. It does not have any side pockets or hidden panniers to store and transport large items. It opens smoothly from the top with 2 zippers. It will easily hold your everyday biking essentials. Emergency tool set, bicycle locks, patch kit, inner tube, gloves, an extra shirt, a novel, a small tire pump, snacks, phones, wallets, and a change purse can all fit rather easily into this handy 9 liter enclosure. It will not hold larger items such as a pair of shoes, or a full size purse. My e-bike rack is approximately 5 inches wide by 15 inches long and this bag fits well and isnât to tall to step over when mounting the bike. This bag is a good choice for anyone who doesnât need to transport large items.

Protection and convenience
This is a really nice bike bag. The hard sides make it keep its shape, yet the bag is very light. The velcro loops are well designed , the straps go through super easy, this bag comes on and off my bike in seconds. Zippers are beefy, product feels well made all around. Plenty of room for all my biking essentials like pump, tube, repair tools, water bottles and a rolled up raincoat.

Great bag
Ordered 4 different bags at the same time to compare. This bag was the hands down winner. Love the hard outer case so the sides or top doesnât collapse in. Zippers are easy to open/close. Plenty of straps to secure it to the rack. Plenty of room inside. Very stylish looking also. So far, love everything about it. Hope it stands the test of time.

Overall, one of the best bags on the market
Nicely constructed bike bag with ample room, grab handle, reasonable rain cover with reflective material, a loop to fasten a clip-on reflector, & sturdy shoulder strap. Also, has two built-in mesh pockets with a wide opening for storage and easy access. Downside is Amazon delivered in a new, oversized box with a used and/or damaged bike bag, & frayed material. Bag was deliberately folded & crushed. Had to do a lengthy exchange process, since Amazon frequently misplace Prime packages while en route to delivery. Also, it wonât fit all bike racks as advertised. My rack is just the right bag length, but cannot strap down the back end without twisting the strap. The lengthy straps are positioned on the extreme ends of the bag, which make it difficult to securely fasten the back end (side furthest from the bike seat). Additionally, the high end of the bag sits level to the back of my bike seat and prevents combined use of a mini saddle bag. Ideal if the ROCKBROS bag placed in reverse direction, but then you have no place to tie down the end straps. I made it work, because overall this bag meets almost all my expectations. Love the wide opening, aerodynamics, and apparent durability.

Lots of capacity.
The hard shell makes these cases more useful and good looking.

Great bag
I like the size, which is large enough to take my essentials. I also like the way the bag straps on to my rack very securely. Be careful about putting a bottled drink in the top bungee as it will work its way out. Recommend using the bungee on top for things that will compress, such a a rain jacket or shirt.
