A multi-use lifestyle backpack that mounts to a bike rack as a pannier or trunk bag. Perfect for commuting, travel and school!





Our entire goal at BiKASE is to design and produce the best bicycling products on the market. We have designed products from phone holders, to seat bags, frame bags and pet carriers. But now we’ve taken on a new and very tricky task…creating a backpack that functions in 3 different way: Backpack, pannier and trunk bag.

This new bag from BiKASE is unique and causes people to turn their heads!

Bike Backpack specifications:

1. The backpack features a separate padded computer compartment with duel zippers to keep your computer well protected and away from the main storage compartment to maximize storage space. Fits up to a 17″ computer.
2. Small front zipper pocket for items such as an energy bar, multi-tool, flat kit, road bike tubes, cell phone, etc.
3. Larger front duel zipper pocket with divider fits such items as pens/pencils, note book, Co2 cartridges, etc.!
4. The reflective webbing on the outside of the large front zipper pocket will hold a ULOCK.
5. The front sock cords with metal hooks will hold a helmet once your ride is completed!
6. There are 2 mesh side pockets for easy access to small items or a water bottle.
7. Tab on the bottom of bag will fit any size or style rear light.
8. A yellow rain cover is in a hidden pocket on the bottom side of bag for better viability and features the stylish BiKASE logo!
9. Top handle for good grip when carrying the bag or installing it as a pannier bag!

Dimensions: 1200 cubic inches
15″ x 8″ x 10″
381 x 203.2 x 254 mm

Mounting System:

Backpack straps are connected using d-rings and can be easily disconnected and stuffed into the back pocket when not in use. Chest strap adds additional comfort and fit.

Disconnect backpack straps from D-rings and hide in back pocket, connecting the pannier clip to the back of the bag keeps the pannier clips secure while riding. Simply pull out the hook from the middle of the back pouch to hook on the bottom of rack when installing pannier.

Trunk Bag:
There are 3 Velcro straps used for the Trunk bag. Simply pull the straps out of the back pouch, wrap them around the underside of the rear rack and tighten as needed. * Note: it is best to install the straps around the braces on rack for most secure fit.

    My husband just got a new bag in the mail from you off Kickstarter, I’m sure he bought this for cycling, but before he could use the bag, I grabbed it from him because I thought it looked cool. I am a mother of 2 little kids and thought this might be to use as a diaper bag while I travel for the holidays. It was great! I was able to keep my large tablet in the computer compartment and all the essentials for the kids in the main pocket and a sippy cup in the side pocket. It made for easy navigation going thru airport security and I loved the look…the red is pretty neat. I’m sure my husband will like this bag too, when I decide to give it back.

    Got the orange bag. Looks great. Nice construction. That was my biggest concern, but this thing is put together very well. Very professional. Kind of a gadget bag, but I like that. A whole lot of options for all kinds of stuff. I’m going to try my best to wear it out, but I expect that will take a long time. Thanks guys.

    I bought this for my boyfriend who commutes to work with two laptops. He loves it because of all the additional pockets which seem to be very thoughtfully placed. Wish I had bought two!

    I have been using for about a month, love the flexibility of mounting on top of rack or as a pannier. Don’t know which way I like best.

    Not just a great pannier, probably the best traveling backpack I’ve ever used. @bentrider (via twitter)

    I’ve had one for about a year. I use it almost every day for my commute and I love it. A pannier on the bike, a backpack on the train. (I have not had cause to use it as a trunk bag yet, but see no reason to doubt it would work just fine in that application.) The flexibility is unbeatable. It isn’t the pannier I’d want for loaded touring, and it isn’t the backpack I’d want for a day hike, but those tasks aren’t what it is meant for. It is meant to be a flexible day-in/day-out commute or run-around bag. For that, it is perfect.
