Dog Bike Trailers

Running a dog alongside a bike works fine for a young, fit kelpie on a quiet street. It falls apart pretty fast on a hot day, a busy road, or with a dog who's getting a bit older in the legs. A dog bike trailer solves all three problems at once: your dog rides in a shaded, ventilated cabin, tracking behind the bike on its own wheels, and you barely notice it's there.

We've been fitting Melbourne riders and their pets out with the right gear for nearly 40 years. Ivanhoe Cycles is still a family-owned Australian bike shop, and our team can talk you through hitch types, sizing and everything else on this page in store if you'd rather chat it through than read on.

Medium or XL: Sizing the Trailer to Your Dog

We stock the Pacific Pet Trailer in two sizes, and the difference comes down to more than just the outer dimensions.

The Medium and XL both have a 30kg carrying capacity, with the main difference being the amount of space and the trailer size. The Medium has a 670 × 420 × 500mm carrying area, 16" quick-release steel wheels and weighs 11.5kg, making it a practical option for smaller dogs. The XL provides a larger 840 × 570 × 560mm carrying area, 20" quick-release steel wheels and a 14.6kg trailer weight, giving larger or older dogs more room to stretch out comfortably on longer rides.

As a rough guide, if your dog is a cavoodle, a beagle or similar, the Medium will do the job nicely. Labradors, larger kelpies and older dogs who appreciate more space tend to do better in the XL. If you're at all unsure, our team can help you match the trailer to your dog's actual weight and build rather than just guessing off breed alone.

How the Hitch Actually Attaches to Your Bike

The trailer connects using a universal hitch that fits most standard 24 to 28 inch bikes, clamping onto the rear axle or dropout rather than the frame itself. A safety strap runs as a backup between the hitch and the trailer. That means if anything ever worked loose, the trailer stays connected to the bike rather than becoming a hazard behind you.

If you've got more than one bike in the household, it's worth knowing that additional hitches can be bought separately. Fit a spare hitch to a second bike and the trailer itself swaps across in a couple of minutes. There’s no need to buy a whole second trailer.

Both sizes fold down flat for storage or to fit in the back of a car, and the quick-release wheels make that even quicker if you're regularly packing the trailer away between rides.

Making Sure Your Dog is Secure and Comfortable 

Every Pacific Pet Trailer comes with an internal safety strap that clips to your dog's harness. Think of it like a seatbelt, so they can't jump out mid ride or shift around too much on corners. The base is a solid, anti-slip polyethylene floor rather than a soft or sagging fabric bottom, which matters more than people might expect. A stable, flat base stops a dog's legs sliding out from under them on tighter turns, particularly if your dog is a bit older.

The cabin itself is enclosed in PVC coated fabric with front weather and insect screens, so your dog gets airflow without being exposed to wind, sun or bugs. Reflectors are fitted front and rear, and a tall safety flag is included as standard, which genuinely does make a difference getting noticed by drivers on shared paths.

Choosing a Trailer for the Way You Actually Ride

A dog trailer built for the bike paths around Yarra Bend is not necessarily the same trailer you'd want for gravel fire trails. If most of your riding stays on paved bike paths and footpaths, either Pacific model will handle that easily, and the standard steel wheels roll smoothly without much fuss.

Heading onto rougher surfaces changes things slightly. Keep an eye on tyre pressure and check the side storage pockets aren't rattling loose gear around on corrugated gravel. The trailer will cope with the occasional dirt path, but it's built first and foremost as a comfortable, stable pet carrier rather than an off-road cargo trailer, so treat smoother routes as its natural home ground.

Looking After Your Trailer Long Term

A dog trailer takes a fair bit of wear over a few years of regular use. That’s why a bit of basic maintenance goes a long way toward keeping it running smoothly.

  • Check tyre pressure roughly monthly, since underinflated tyres make the trailer noticeably harder to tow and wear unevenly over time. 
  • Give the zipper tracks on the mesh screens a wipe down after muddy or sandy rides, as grit works its way in and can jam a zip surprisingly quickly. 
  • It's worth giving the hitch coupling a once over every few months too, checking the pin isn't showing signs of wear.
  • Confirm the axle hub is still locking securely before every ride. 

Complete Your Setup at Ivanhoe Cycles

If you're pairing your new trailer with other gear for longer rides, our hybrid bikes handle the extra towing weight comfortably, and a set of bike panniers covers whatever won't fit in the trailer itself. Riding with a dog also tends to mean quieter, more considered rides, so it's worth checking your bike lights are up to scratch if you're likely to be out later than planned. For the full range including child and cargo trailers, our bike trailers collection covers everything else we stock.

Frequently Asked Questions

How does a universal trailer coupler hitch attach to a standard adult bicycle axle?

The hitch clamps onto your rear axle or dropout rather than the bike frame, using a quick-release mechanism. A safety strap then runs from the hitch to the trailer as a backup connection.

What is the maximum weight capacity for a medium versus an extra-large pet trailer model?

The Pacific Pet Trailer Medium carries up to 30kg, and the XL carries up to 40kg. Choose based on your dog's actual weight rather than breed alone, since there's plenty of size variation within any breed.

Does the trailer base sag or bend when a heavier dog sits inside the cabin?

No. Both sizes use a rigid, anti-slip polyethylene base rather than a soft fabric floor, so it holds its shape under load and gives your dog stable footing even on corners.

Can I purchase an additional axle hitch to swap the trailer between two different bikes easily?

Yes, additional hitches are sold separately. Fit one to each bike and the trailer itself swaps across in a couple of minutes.

Are the mesh panels and vinyl covers waterproof enough to handle sudden downpours?

The PVC coated fabric and weather screens handle light rain and wind well, though we'd still recommend getting your dog out of a sudden heavy downpour where you can, the same as you would with any pet.

Can a pet trailer be safely used behind high-torque electric commuter or mountain bikes?

Yes, provided the hitch is rated for the combined weight of the trailer and your dog, which both Pacific models are. The extra torque from an e-bike isn't an issue for the hitch itself, though we'd suggest easing off acceleration a little more gently than you might solo, for your dog's comfort as much as anything.
