Flex vs Standard Mount
Which mount should I get?
Standard Rigid Mount
This is the original mount that has come with the BuddyRider® since its inception. It features a simple, fixed-position design and works well with most medium to large bike frames, offering a straightforward and proven setup.
Flex Mount (Flex-Arm® Upgrade)
An upgrade to replace the existing support arm, the Flex-Arm® dramatically improves the BuddyRider® position through enhanced adjustability—forward and backward, upward and downward—and can even be angled to tilt over the handlebars if needed. It’s especially beneficial for small frame bikes and helps smaller riders avoid knee interference while pedaling, while also allowing riders of all sizes (XS to XXL) to fine-tune and optimize their setup for a more comfortable riding experience.
Bottom line:
If you’re riding a smaller bike or want more adjustability to dial in your fit, the Flex Mount is the better choice. If you prefer the original, fixed-position design that has been trusted since the beginning, the Standard Rigid Mount is a reliable option.
Will the Buddyrider fit my bike?
The BuddyRider® bicycle pet seat is suitable for most bicycle styles, however there are some fitting requirements.
Receiver Height
At least 4.45cm (1 3/4”) of seat post must be revealed to attach the BuddyRider®
Have a suspension seat post?
You’ll need to replace your suspension seat post with a rigid seat post so that the BuddyRider® is mounted high enough both for fit and your comfort. They are available at most bike stores.
Have a carbon fibre or titanium seat post?
To prevent damage, you’ll need to replace your carbon fibre or titanium seat posts with an aluminum or steel seat post.
Flex Mount (Flex-Arm®): A Game Changer
The Flex-Arm® is designed to dramatically expand bike compatibility and improve fit. With multi-directional adjustability (forward/backward, up/down, and tilt), it allows you to position the BuddyRider® exactly where you need it.
- Fits small frame bikes more easily
Reduces knee interference for riders with longer legs - Makes mounting easier for shorter riders
- Adds clearance between the seat, rider, and handlebars
- Compatible with a wider range of bikes, including many e-bikes
Bottom line:
If you’re unsure whether the BuddyRider® will fit your bike, the Flex Mount gives you the flexibility to make it work—across more bike styles and rider sizes (XS–XXL).

- Ideal for dogs up to 6 kg (13 lbs)

Will my dog fit in the Buddyrider™?
The Buddyrider™ was originally designed for the inventor's 23 pound Parsons Russell Terrier and made with as much flexibility in mind as possible. Obviously some dogs fit better than others, but the dog bicycle seat should fit dogs from 5 to 25 lbs. The following guide goes into a little more detail and discusses different breeds. The information in the guide is by no means 100% accurate in every case, but will hopefully make your decision a little easier when considering size.
Buddyrider Series 2 Description
The Buddyrider™ dog bicycle seat is a fun way to safely take your dog along with you on bike rides. Unlike other bicycle dog carriers and front or rear mounted dog bike baskets, the Buddyrider™ is mounted over the center of the bike so the extra weight has virtually no effect on handling. This is the sturdiest and most stable dog bike seat we have tested. For larger breeds a dog bike trailer or dog bike leash is ideal, but for smaller dogs weighing up to 25 pounds, there is no better alternative than the Buddyrider™. We even offer a 100% Satisfaction Guarantee & Warranty

Buddyrider Safety and Installation Instructions
Read instructions carefully before placing a pet the Buddyrider dog bike seat. Failure to follow these instructions could result in serious injury. By attaching the Buddyrider pet seat to a bicycle you are acknowledging that you have read and understand the warnings and instructions, and understand the inherent dangers that may be associated with transporting a pet on a bicycle. Only experienced adult cyclists, who are very confident in their abilities as a rider should transport a pet using this seat.
Buddyrider Installation Instructions
1. Assemble the Buddyrider dog bike seat by raising the front platform and securing the center support arm with one of the supplied screws and a washer. (See Fig 1. above)
2. Attach the metal bar to your bicycle seat post. There must be at least 1.9 - 2.5 cm of post exposed below the seat to make this connection. Keep this connection as high up the seat post as possible. This will give the rider more legroom when peddling.
3. Position the Buddyrider pet seat on the metal bar as far forward as possible without causing any interference with the steering post or handle bars of the bicycle.
4. Make a small pencil mark on the metal bar right behind the dog bike seat.
5. Remove the pet seat and also the metal bar using the quick release pin.
6. Position the Buddyrider seat on the metal bar in the same position as it was while on the bicycle and turn both of them upside down. Slide the pet seat along the metal bar as if to cover the pencil mark until four of the drill holes simultaneously line up with the screw sockets on the bottom of the pet seat.
7. Using four of the screws and washers provided, mount the pet seat to the metal bar. Make sure all four screws are in position before tightening. Steps 1 through 7 should never need to be re-done unless the pet seat is mounted on a different size bicycle, in which case the four screws may have to be re-located in different holes to adjust the length.
8. Install the assembled pet seat to the bicycle using the quick release pin and be sure to secure that with the cotter pin provided or a small pad lock.
Safety Harness - Install and connect as shown
Your dog must be secured in the seat at all times using the safety harness provided.
Buddyrider™ Harness Adjustment

1. Place your dog in the Buddyrider seat in a sitting position as far back in the seat as possible.
2. Connect and position the rear buckle over your pet's shoulders and adjust the rear straps equally.
3. Position the collar strap around your pet's neck so it is just below your dog's own collar. Connect the front buckle and adjust the collar strap to size.
4. When your dog is in the sitting position with their front legs along the upper platform or straight down, adjust the front straps equally so your pet is restrained from standing. Just like a seat belt on a child car seat, the Buddyrider harness is designed to limit unnecessary movement so your pet remains in a safe position to enjoy the ride.
- Prior to using, check that the dog bike seat is secure to the bicycle and no parts are cracked, loose, missing, or broken.
- Due to the size and weight associated with transporting a dog on a bicycle, extreme care must be taken at all times. The rider may be required to make quick corrective action when the pet moves its weight.
- Care should be taken when placing your dog into the seat, and also when removing them. This should be done in a safe place away from distractions such as other pets and traffic.
- Initial rides should be brief, over smooth ground, in a safe location and away from all distractions.
- Increase the duration only when both rider and dog become accustomed and confidant using the Buddyrider.
- Never leave a dog unattended in this bicycle seat. Due to the higher center of gravity, a bicycle may fall over if parked on its stand or without proper support.
- Do not allow your dog to become a distraction when riding. Keep your focus on the safe operation of your bicycle, the rules of the road, the environment around you and other cyclists, pedestrians and vehicular traffic.

What makes the Buddyrider ideal for riding with my dog?
With a Buddyrider, your dog sits in a comfortable secured position in front of the rider and between the seat and the handlebars. This optimizes the riding experience for both rider and buddy alike by allowing both a full field of view while at the same time keeping both essentially snuggled together. Riders and dogs love this! The Buddyrider is centrally mounted between the rider and the handlebar. This gives the rider better balance and control because the additional weight is more evenly distributed at the center of the bike – not on the handlebars or rear wheel. Buddyrider’s central positioning also allows the rider to interact with their buddy – so you’re always in tune with how your dog is reacting to the bike and the surrounding environment.
How does my dog not jump out of the Buddyrider?
Your dog is secured in the Buddyrider using a four-point system, including a collar and four tie-down straps. Two tie-down straps are attached to the front of the seat of the Buddyrider. Two are positioned at the back. Each tie-down is threaded through the collars so you can adjust the fit for your dog.
Will my dog be comfortable in the Buddyrider?
The Buddyrider is designed to let your dog adjust its position to whatever’s most comfortable. Your buddy can sit upright or rest its front paws on the paw deck. You can optionally add a thick foam and fleece lined booster seat cushion for added comfort (ideal for dogs 12 lbs or less).
How do I get my dog used to the Buddyrider?
To get your buddy ready for their first ride, we recommend getting them comfortable in the seat while it is on the ground. Have a few treats ready to help encourage them if they’re hesitant. Once you and your dog are ready, attach the Buddyrider to your bike. Put your dog in and walk your bike to get them used to the idea, praising them along the way. When your dog is comfortable, start with short rides to see how they do and then slowly increase the distance. Many of our riders report that their buddies are fully adjusted to their Buddyriders after a few short rides.
Will my dog fit the Buddyrider?
The Buddyrider is designed for dogs between 2.75kg (6lbs) and 11.34kg (25lbs) with as much flexibility as possible. . Dogs, like humans, come in all different shapes and sizes! Reference this page to help you determine if your dog will fit your Buddyrider. If it doesn’t fit, not to worry - return it within 30 days.
Will the Buddyrider fit my bike?
The Buddyrider has been designed to fit the vast majority of bike styles. Check out our Bike Guide to confirm. If it doesn’t fit, not to worry - return it within 30 days.
I have a carbon fiber/titanium bike frame. Can I use the Buddyrider?
Because the Buddyrider receiver is made out of aluminum, it could potentially damage the carbon fiber or titanium seat posts. If you have a carbon fiber/titanium seat post, you should replace it with an aluminum or steel seat post before attaching your Buddyrider. Replacement seat posts are easy to come by at any bicycle shop.
How easy is it to take the Buddyrider on and off the bike?
A quick-release pin-and-clip makes it easy to remove your Buddyrider from your bike. A discreet, 10.16cm (4") receiver stays on the seat post – so you’re always ready to re-attach and go for a ride with your buddy! Optionally, purchase a second receiver to make it a breeze to switch between bikes.
How much is shipping?
Shipping is FREE. The price of the Buddyrider includes free priority shipping from our US warehouse, ensuring that you receive your Buddyrider as fast as possible. Typically the Buddyrider will arrive within 3 business days from the time of purchase.
Can I return the Buddyrider?
We want you to love your Buddyrider as much as we do. If you don’t – if your dog doesn’t fit your Buddyrider or if it doesn’t fit your bike – you have 30 days from receipt of your order to return it with all its original packaging. Please ensure all the parts are wrapped carefully to prevent any damage or pieces from going missing.
