ROCKBROS Bike Saddle Bag Small Seat Bag Bicycle Bag Under Seat Bike Accessories Storage Pouch Ultralight Cycling Wedge Pack for Road Mountain MTB Foldable Bike

Not a huge bag to ride along with you but perfect for the keys to your vehicle that you drove in, a bit of money for a stop to buy a drink along your ride and room for an extra power or protein bar you may want to bring.

I bought this to store my tire tools and it worked perfectly. Plenty of room for patches, tools, etc.

This bag is the perfect size for packing a spare tube, CO2, and tire wrenches. But, as one of the previous reviewers noted, the bag unzips itself during a ride. I've taped it shut, but that seems like a serious design flaw.As an update, ROCKBROS got in touch with me and offered a full refund, which was really nice. So, I'll upgrade my review by a star.

Good bag. Sleek but fits tire and tools.

Some would say this is a small saddle bag. But I was able to fit my very average-sized set of keys in it whenever I went biking. My keys feel very snug and comfortable in this "small" saddle bag. I'm sure both parties are satisfied by the size.

The bag is the perfect size for a mountain bike tire repair kit (tire levers, puncture kit (if tubless), a few cannisters and room leftover. I love the size - BUT - the straps won't hold on the MTB ride. You have to use another velcro strap that's long enough or zip ties. So the extra work to keep it on the bike is worth it.Now, I have another Rockbros bag for my gravel bike that's larger and those straps haven't moved in two years. This is just a smaller bag, smaller straps, not enough grip. Its ok, just get a long zip tie and you'll be fine.

Super small. Like fits an extra tube that is taken out of the box. If you need uber small, this is for you!

I have been using this as a bike saddle bag for only 3 weeks, and it is clearly low quality. I am in the process of returning it as it does not function properly as a saddlebag. I have two major complaints:1. The zipper is defective. It does not stay zipped shut, rendering the bag useless. It's as if the zipper is too loose, so any bumps will slowly unzip it on its own. This is clearly problematic for your stuff inside. Nearly every ride would end with the zipper as it appears in the attached photo.2. Overall material quality is very low. After only 3 weeks of use, there are multiple points of material failure. with cracks, rips, and tears. I expect this after years given the tough conditions saddle bags go through, not weeks.Overall the small size and looks are nice, but given the fundamental issues this product is useless.
