BUSATIA Bike Seat Bag,Bike Seat Bag with Water Bottle Holder, Bicycle Saddle Bag Under Seat Waterproof Cycling Seat Pack for Mountain Road Bikes, Black

Nice size. Quality seems to be real good. I probably should have ordered 4 more because i have 5 bikes. only thing is it would have been nice to some way to quickly release it from the bike. I don't want to leave it on bike when i'm not around

This bag is well made and has large access. Due to length, the seat must be extended very high. Most people of average height will not be able to mount it as shown.

I "like" the good quality for the relatively low price! It is much bigger/more internal volume than another one that I have. I "like" having the extra small "bottle holder," and that the flashing rear light that I've mounted on the post, . . can now be mounted on the back of the post saddle bag.

When I saw this seat post bag, I wanted it. I got it today and Wow... I'm glad I bought it! It has lots of space inside for tools, a rag, snacks and misc. items. The bottle holder holds my tall 33.8oz water bottle. I like the material. The zippers are nice and zip smoothly. Tucked behind me seat it out of the way. It's like a trunk that you can stash your stuff. It's part of my bike cargo carriers. This bag should fit most any bike. I plan to use it on my other bikes when I ride them. It will be my go to bag. Happy Smiling bike rides for you.

Great truly recommend for all bikers, the bag comes in handy, way better than your average water bottle holders.

My bike is size Small and I cant use the bottle holder so I cut it off. I don't notice the carry bag when riding and it holds everything I need.

I just got my bag!! I decided to get this instead of just a water bottle holder! It is a good size bag! My keys and a few other things will fit easily!!

Amazing bag! It fits perfectly on my bike seat pole. The water bottle holder is clutch.

Nice value, quick shipping!

works perfectly as described
