It’s been almost two years since my last Bikase review when the company’s owner contacted me with a few new products to test. Like the Beetle X phone case, these seat pack samples were well made, durable, functional, and affordably priced.

The Momentum seat pack comes in four sizes, and I received the medium and large versions to test. Installation is quick, with two side buckle straps attaching to the seat rails and a single Velcro strap going around the seat post. It fits snugly, with no movement or swaying when riding.
For added visibility in low light conditions, there are side reflective strips and a strap to hang a rear light. Internally there’s a mesh pocket to store small items and an elastic band to secure CO2 canisters or other items.
I unintentionally tested the water-repellant 840 Denier nylon on my very first ride. After installing the bag on my gravel bike, I ventured onto a local limestone trail which ended up being a mucky mess. The bag became encrusted in wet limestone, but the inside of the case stayed perfectly dry.

Upon returning home, I hosed down the bike and bag. The bag easily came clean, and the zipper functioned just fine. I’ve had issues with other brands of seat bags where the zipper no longer works after a muddy ride. The Bikase seat bag is definitely a winner!
Tube & Tool Caddie

Bikase’s Tube and Tool Caddie is an excellent option for the minimalistic rider. It holds everything you need to fix/change a flat from a road to a fat tire. With separate compartments for tools and CO2 canisters, everything is secure and won’t fall out. Just pack it up and install it on the seat rails. It’s durable and functional.

Ideal for all your bikes from road to fat

I enjoyed this review. I generally use bags made by Topeak but this one looks like a viable option for the future. Thanks!
I’m sorry, but that bag looks like, and is made like, millions of other bags out there, nothing special just a seat bag that, well, darn it, isn’t water proof like millions of others! Nothing like a nice ride in the rain and opening up your bag to find everything inside soaking wet. So, a while back when Topeak first came out with their Wedge Drybag I bought one, and no more wet contents while riding in the rain, in fact, not even remotely damp inside, and the bag lasts a long time. I now own 3 of those bags and won’t buy any other.
The connected zipper handle on the large size (as seen on company website) looks like a nicer feature. Some bags are a bear to get zipped & unzipped.
