Steps to Attach Trunk Bag onto the Rear Rack

Step 1: Identify the Front of the Trunk Bag

Look at the overall shape of the bag.
The front of the bag is the narrower, tapered end.
The back of the bag is wider and more squared-off.

Step 2: Align the Trunk Bag with the Rear Rack

Hold the trunk bag base above the rear rack.
Line up the front and rear pins with the slots on the rack’s top plate.
Make sure the front of the trunk bag is facing the seat.

Step 3: Snap the Trunk Bag into Place

Push the trunk bag straight down and back until you hear a “click.”
This sound confirms the trunk bag is securely locked onto the rack.

Step 4: Check Trunk Bag is Secured

You shouldn’t see any gap between the trunk bag and the rack.

Step 5: To Remove the Trunk Bag

To remove the trunk bag, pull the locking pin downward to release.
Then push the trunk bag forward toward the seat to disengage it from the rack.

Keep Your Trunk Bag Secure

Add an extra layer of protection with the MOD Snap-On Lock, designed to help secure your trunk bag and compatible accessories.
