Quick Summary
The KEMIMOTO Rear Bike Rack Bag is an 8L bicycle rear rack bag made from water-resistant PVC. It is a soft-shell bag with straps for rack attachment and a strap for taillight installation, and it can also be carried as a crossbody bag or handbag.
Key buying points include the stated 8L capacity, the rack fit range, and the note that the seams are not water-resistant. If you need a rear bag that can be moved from the bike to hand carry, those details matter before you choose a version.

What to Compare Before Buying
- Rack size: Compare the stated fit range with your rear rack dimensions, especially width and length.
- Storage needs: Check whether 8L is enough for the items you want to carry.
- Weather exposure: The bag is water-resistant, but the seams are not, so compare it with the conditions you expect.
- Carry style: Consider whether you want a bag that can also be used as a crossbody bag or handbag when off the bike.
- Lighting setup: If you plan to mount a taillight, confirm that your light and mounting setup work with the included strap.
Compatibility, Size and Fit
This bag is intended for rear racks that fall within the stated size range. The fit note also says it is not for extremely short or narrow rear frames, so rack shape matters as much as width and length.
Because the bag is soft-shell, it is worth checking how much shape your rack gives it once installed. A quick measurement of the rack before buying is the most useful way to avoid a mismatch.
Before You Decide
Confirm your rear rack fits within the stated width and length range. Check whether 8L matches the amount of space you need, and keep in mind that the seams are not water-resistant. If you want off-bike carrying, the hand straps and shoulder strap add flexibility.
