Buy It!
This is the BEST bike saddle bag Iâve ever purchased. Velcro is strong. No worries about it coming undone. Stitching and material is high-quality. No worries about it ripping. Zipper is a sturdy and strong fastener. Size of bag is just right. Fits perfectly and snuggly under the seat and is big enough to hold what every cyclist needs. No need to cram things in it, or worse yet, feel like youâre hauling a suitcase along for your ride. They thought of everything. Whether youâre a serious cyclist or a casual one, this is the saddle bag for you. Buy it!

Very nice bag ⦠not perfect
Letâs all agree nothing is perfect. The under saddle bag is very nice. Material seems quality, the zippers are decent, Velcro straps seem well sewn and quality. Overall a super nice bag ! Roomy and easy to fill

One Wasn’t Enough…good enough for one on each bike
Just ordered 2 more. Good size for carry on tools, etc. Stable attachment under saddle…no wobble.

Works great
Looks great and functions well. Has plenty of room for multitool, patch kit, and protein bars. Easy to install and remove.

Compact with easy Access
This bag sits up against the seat really close. and since it is a bit stiff you can fit critical items in it. I like bags that have straps while this has Velcro strips. I guess you can snug it up quicker but getting through the rail is not as easy but not a deal breaker. it has an attachment for a light which is nice even though I am sure the light sways since it is not a solid attachment. might not work so well for rear camera or radar. I do not know. has a few inner pockets so you can sperate things and I like the net in the opening part so I can have easy access to keys or money or any small item that you might want to have easy access to during a ride. A wallet is not going to fit if you have tools and bars and CO2 inflater. Maybe if wallet is small. mine is not.

Gets the job done
It’s hard to really write an in-depth review of an under-seat bike bag. But I’ll hit the high points. I haven’t tested the theory, but it seems waterproof, or at least very water resistant. The zippers move freely, and it has room for two tubes, 2 CO2 canisters, tire tools, and a dollar bill. IYKYK. The straps are long enough to mount securely without feeling like you’re putting tension on them just trying to get the bag mounted. And I like that it has a spot for a rear reflector or light to mount on the rear. I may review again after I’ve used it for a while, but so far so good.

Its cool but it does not work for the heybike mars 2.0
Does exactly as specified. It didn’t fit my bike but it fits most other bikes so I gave it to a friend since I was outside the return policy.

Quality is good and the material is good. Its small also and only fits 1pc of 29″ tube on it.

Very good quality. Perfect for a small pump, wallet, tube and keys.
