- Attach the Wheels: Insert the quick-attach wheels into the designated slots on the trailer frame. Ensure they click securely into place.
- Install Padded Base: Place the removable padded base inside the trailer for your pet's comfort.
- Connect Trailer Arm: Attach the trailer arm to the front of the carriage.
- Attach Hitch to Bicycle: Secure the quick-attach hitch mechanism to the rear axle of your bicycle. Ensure it is firmly tightened and does not interfere with bicycle operation.
- Install Signal Flag: Insert the signal flag into its designated holder on the trailer for increased visibility.

5. Operating Instructions
Using your TRIXIE Dog Bike Trailer effectively and safely:
- Pet Entry and Exit: The trailer features zippered front and rear doors for easy access. Guide your dog into the trailer gently.
- Secure Your Pet: Once your dog is inside, attach their harness to the integrated safety leash. This prevents them from moving unexpectedly or exiting the trailer during a ride.
- Ventilation and Protection: The durable mesh front panel provides ventilation. For weather protection, use the closable cover and rain shield as needed.
- Storage: Two side pockets are available for carrying small essentials like treats, waste bags, or a water bottle.

6. Maintenance
Proper maintenance ensures the longevity and safe operation of your trailer:
- Cleaning: The fabric can be spot cleaned with a damp cloth and mild detergent. Allow to air dry completely. The padded base is removable for easier cleaning.
- Wheel Care: Regularly check the wheels for debris and ensure they spin freely. Maintain proper tire pressure as indicated on the tires.
- Storage: When not in use, the trailer folds down easily for space-saving storage. Store in a dry place away from direct sunlight to prevent material degradation.
- Inspections: Periodically inspect all moving parts, fasteners, and fabric for wear, damage, or loose connections. Replace any damaged parts immediately.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty assembling crossbar/frame | New fabric is very tight and needs to stretch. | Apply firm pressure to secure the crossbar. Once assembled, leave it for a couple of days to allow the fabric to stretch. Subsequent assemblies will be easier. |
| Trailer feels unstable during use | Loose wheel attachment or improper hitch connection. | Ensure wheels are fully engaged and locked. Verify the hitch is securely fastened to the bicycle's rear axle. Check tire pressure. |
| Pet reluctant to enter trailer | Unfamiliarity or anxiety. | Introduce the trailer gradually. Allow your pet to explore it while stationary. Use treats and positive reinforcement. Practice short, slow rides before longer journeys. |
