The K9 cargo bike for dogs left view

Ride with your dogs

The K9 was designed with pets in mind! Great for senior dogs and younger dogs alike. Keep muddy paws out of the back seat of your SUV and get some exercise while pedaling out to the dog park.

 

The roomy interior can hold up to two big lab-sized pups, with a weight limit of 220 pounds. And with a swing-open door on the front, your dogs will be able to hop in the bike by themselves.

Unbelievable Stopping Power

With an electric cargo bike, it's crucial to have brakes that can handle a heavy bike traveling at fast speeds. This year, we took things up a notch and added ultra-powerful front and rear hydraulic disc brakes. A small squeeze on the levers will bring you to a stop almost instantly. and you can rest assured that your precious cargo will be super secure.

 

One unique challenge with cargo bikes, is that the front two brakes must be perfectly balanced at all times in order to be safe to ride. With mechanical brakes, this means you'd have to find the time for frequent service and inconvenient tune-ups. Hydraulic brakes overcome this, by requiring much less on-going maintenance. So you can spend less time in the shop, and more time out riding with the fam!

The 500W DAPU M155 is our tried and true geared hub motor. With 45 Nm of torque, the motor makes riding a bike full of kids easy and FUN, even in hilly areas.

 

Electric battery for dog cargo bike in rear rack

48v 13.6Ah Samsung Battery

Our batteries use only genuine Samsung 35E cells, which lead the e-bike industry in charge capacity and reliability. Has a range of 25-35 miles and takes 4-6 hours to charge from empty. Extremely high quality construction, using internal spray foam to keep battery cells waterproof and immovable, and featuring internal heat sensor cut offs, for years of durable and safe battery use.

 

Thumb throttle for electric dog cargo bike

Side-pull Comfort Thumb Throttle

Allows for full manual control of the motor, and can be used with, or independently of, pedal assist. The side-pull motion of the throttle fits the natural inward motion of your thumb, for maximum comfort and ease of use.

 

Spanninga Axendo 60 headlight for e-cargo dog bike

Spanninga Axendo 60 Headlight

Dutch company Spanninga has been innovating high-performance bicycle lights for nearly 100 years. The 60 lux output from 2 high-power REBEL© LEDs has amazing visibility from both front and lateral sides, lighting your way, and keeping you seen.

 

Spannigna Lineo taillight for electric dog trike

Built-In Spanninga Lineo Tail Light

2 bright and distinctive LED "Light Lines" provide extremely high performance, with rear and side visibility up to nearly 2000 feet. The light is built into the battery pack, and can be turned on from the handlebars, just like the headlight.

 

DAPU control panel display for electric bike

Control Panel with USB Charger

Charge your phone while blasting Disney hits from your bluetooth speaker, using the built-in USB charger. Also features an odometer, speedometer, pedal assist level, and battery life indicator.

 

Torque sensor pedal assist for e-bike

Torque Sensor Pedal Assist

Unlike magnet sensors, which can feel unnatural and can react slowly to changes in riding conditions, our torque sensor intuitively senses your pressure changes on the pedals, and adjusts the motor output exactly to your needs in real time!

 

electric cargo bike charger

UL Certified Smart Charger

Our Smart Charger automatically stops charging when your battery is full (and lets you know with the red/green LED indicator), protecting the life of your battery. The UL certification means it meets the strictest guidelines for electrical and fire safety, as well as longevity, resistance, and durability.

 

Waterproof wiring harness for electric cargo bike

Waterproof Quick-Connectors

In the rare event that one of our high-quality electrical components fail, part replacement is a cinch, with waterproof quick-connectors right underneath the handlebars. No need to run wires through the frame or call a mechanic for most repairs!

 

The Cargo Box

Removable Locking Storage Bench

Bring up to 2 kids along with one bench and seat belts. They install and remove without tools, so it's easy to re-configure your bike as needed. No kids? Use the bench as a locking storage box for dog treats and toys!

 

The K9 dog cargo bike interior view with dog bed and leash

Optional Add-On: Folding Dog Bed & Double-Clip Leash

The optional dog bed lays flat, to make a comfortable ride for puppy. With the storage bench installed, the front of the bed can fold, making a raised step so little dogs can see out of the box. The optional double-clip leash clips onto both the included mount and your dog's collar.

 

Swing Open Front Door

Save your back... no need to lift your 80 pound lab into the bike. The door allows dogs to hop up into the bike by themselves (and kids like it too!)

 

Step for child on side of the K9 dog cargo bike

Dual EZ-Step System

Two anti-slip textured child steps are located on either side of the box, for dog owners who want to bring along the kids!

 

Rubber liner on top of The K9 cargo box

Protective Rubber Liner

After years of selling cargo bikes, we've learned that 90% of cargo box wear-and-tear occurs along the top edge. In our case, from hanging kids' bikes over the top! The protective rubber liner will prevent all top-edge damage, and prevent rain and moisture from penetrating the wood, giving you years of use, while providing a nice aesthetic trim.

 

Piece of marine grade plywood with nice finish

Durable Marine-Grade Plywood

Designed for prolonged exposure in humid, wet, and coastal conditions, our coated marine plywood is assembled with waterproof glue and is resistant to delamination. With proper care, you'll enjoy years of outdoor use.

 

Key Components

Schwalbe Big Apple tire closeup

Schwalbe Big Apple Tires

These tires are a dream! Schwalbe's "Balloonbike" air-suspension technology makes a huge difference for the riding comfort of both rider and children.

 

Bumps and vibrations in the road are absorbed for a smooth, comfortable ride. While at the same time, the double-nylon Raceguard layer provides incredible durability and flat-tire protection... because no parent should have to change a flat on the side of the road while juggling toddlers!

 

Tektro hydraulic brake lever with parkin brake

Front and Rear Hydraulic Brakes

Your precious cargo will be super-safe thanks to the unbelievable stopping power provided by the hydraulic brakes on both front and rear wheels. Each brake lever is equipped with a parking brake switch, so that the bike stays still while you load up the kids.

 

Shimano acera 8-speed shifter

8-Speed Shimano Gears

Combined with the motor, the 8-seed Shimano Acera shifter and gears will allow you to easily get started from a stop, as well as conquer any hill in your path.

 

Anti-Tip Smart Frame Technology

A cargo bike with 3 wheels handles differently than a regular bicycle. Turns have to be taken slower, especially when turning onto an incline. Our anti-tip smart frame technology helps counteract these forces by automatically leaning your weight into the direction of the turn, so that all wheels stay firmly planted.

 

Side view of K9 cargo bike for dogs

Extended Handlebars for Upright Seating

Designed to provide comfortable upright posture, like riding a beach cruiser. The handlebars extend back to be within easy reach of riders of all sizes.

 

Steering damper underneath The K9

Steering Damper

The gas-spring steering damper underneath the cargo box is beefier than our last model and minimizes side-to-side steering wobble. And at higher speeds, the bike tracks straighter as is safer to ride than a damper-less trike.

 

Rear view of the K9 dog trike turning

Improved Turning Radius

We adjusted the location of the steering bumpers to improve the turning radius of the bike over previous models. Turning the hassle of 3-point turns into easy 180s!

 

Selle Royal Freeway City saddle

Easy-Adjust Selle Royal Saddle

The comfortable, Italian-designed Freeway City saddle is made by Selle Royal, the world's leading brand of bicycle saddles. Made for sitting upright, the Slow Fit Foam technology is a slow-moving memory foam that adapts to the body and guarantees uniform weight distribution.

Strong Square Frame with ED Coating

Frame design features durable square tubing, and is ED coated for long-lasting rust protection. The outside is CNC painted, not powder coated, for a beautiful, even finish.

 

Rear rack with electric cargo bike battery inside

Versatile Rear Rack

Load up your saddle bags or strap down the boogie board and cooler. Our rear rack will support up to 66 pounds of gear. Or add the Yepp child seat to bring along an extra kid!

 

Glossy black full coverage bicycle fender

Wide, Full Coverage Fenders

A must for any cargo bike, the full coverage front and rear fenders prevent water and mud from spraying up on you or the kids.

Absolutely amazing Bike! So much joy!!

Thanks Chris, glad you and the dog are enjoying the bike!

Rich and Charlie Cruising!

My husband cannot drive anymore but the bunch bike is giving many hours of enjoyment for him and our dog, Charlie! The whole neighborhood loves to watch Rich and Charlie cruise down in the street in the red bike. Thank you!

Hi Susan,

Thanks for sharing Rich and Charlie's experience! We have many customers sum up their experience with the bike with one word: Freedom.

Whether that's a stay at home mom wanting to get outside and be active (while keeping the kids entertained), or people who for one reason another aren't able to drive, the Bunch Bike makes new experiences possible for families!

Happy to hear it's a hit in the neighborhood! Take care,

Aaron @ Bunch

Love this bike!!

I’ve had a 7-speed cargo bike for many years and finally pulled the trigger on an electric one. Bunch Bikes had it delivered very quickly, completely ready to ride. My kids and dogs love it and it’s an amazing way to get around for short trips to the park or grocery store. The customer service department was very responsive and helpful for a few issues we had with the bike and I’m very glad we chose Bunch Bikes to make this purchase. The bike works like a dream and people do stop and stare when you ride by. A true feat of engineering! Highly recommend Bunch Bikes if you are considering an electric bike for the whole family (dogs included of course!). Absolutely love mine!

Hey Christopher,

Congrats on riding an 'acoustic' cargo bike for years, I'm impressed! Once you go electric, you never go back though... most people end up riding further and more often than they would otherwise.

I am very happy to hear that our customer service team took care of you so well too. You'll find that that will always be the case whenever you reach out to us needing help.

And I have to know... what are these dog goggles and where do I get some for my pups???

Such a fun addition to the family!

I got this for my wife for her birthday, to bike around with our dog. Our dog loves it, my wife loves it, and we use it multiple times a weekend to bike to the farmer’s market or to different parks. I use it to pick up groceries. We love it, and we weren’t big car users to begin with but our one car sits even more unused now that we have this super fun ride. Highly recommend!

Hey Lars,

So happy to hear that our bike is helping to facilitate a more entrenched bike lifestyle for your family. The car sitting unused is music to my ears!

Keep it up!

Pablo's test run..

So far I love this bike. My canine companion loves going for spins.

Hey Pablo,

I am so thrilled to have an esteemed dog psychologist such as yourself enjoying our bike. It's great that you have a companion like William to ride you to school. Looks like you're having a blast!

Great Bike

Great bike. Love how it came fully assembled and ready to go, Willow loves it!

Hey Ric,

We like to make it easy for our customers to get out and riding! A good customer experience is what we do!

Glad Willow loves his new ride!

Amazing ride!

The K-9 Bunch bike is just amazing. Our dog is getting a little older so her range is limited. There’s enough room in front for both my wife and our golden retriever. Boy, do we get some looks! Easy to drive, terrific electric set up, just a solid bicycle.

Hey James,

Love this, those are some happy dogs! One of my favorite wraps that we've done on a bike. I hope all of those 'looks' turn into visits to your website!

Fantastic K9 Bunch Bike

I love ❤️ this bike and my two English Bulldogs love it also. I can get some exercise while my pups enjoy time on the road also. The pedal assist is an awesome feature when going up hills and the Bunch Bike display is very user friendly.

Hey Eric,

Mia and Romeo are the cutest and are 2 lucky dogs! So thoughtful of you to get the shade for them

Glad you guys are loving the bike!

Excellent and easy

We love our Bunch bike. Our grand kids ask to travel to school, summer camp, errands and to run the dog in the Bunch bike.
It took 3 days for our dog to become comfortable and now he jumps in without being asked.

I tried alternative 2 wheel electric cargo bikes that could carry two children in front but was unable to control or steer at low speeds.
My adult children use the bike regularly to carry our grandchildren and groceries.
Now I commute to work in it.
I go for days without getting into the car.
Excellent choice and maybe too easy to learn to use. I should walk more- Bunch bike less.
Chris

Hey Chris,

One of my favorite things about the Bunch Bike is how easy it is to load up and get going. No need to worry about keeping the bike balanced at low speeds or when coming to a stop.

Replacing car trips and getting active while having fun with the family is what we're all about! Glad to hear the whole family is getting to enjoy using your bike!

Dog, kids and wheelchair, we can still go biking.

I love to bike and it used to feel like I should just take the car if we were taking the dog or a wheelchair. I love how easy it is to still take a bike now!

Not being forced to take the car = freedom!

I'm so happy to see how you guys are able to get your life done on the bike.

-Aaron @ Bunch
