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.
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!
Our new state-of-the-art 48v 13.6Ah battery features genuine Samsung 35E cells, the best and most reliable cells available in the e-bike market today. Get up to 35 miles per charge and enjoy years of use on your bike.
Our high-power 500w motor delivers 45 Nm of torque and allows you to conquer hills and grocery runs like a boss. You'll feel like your legs just got an upgrade!
Expand below for a more detailed look at The K9
500W Hub Motor
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.
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.
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
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.
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.
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
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!
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 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!
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!
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!)
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!
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.
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.
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!
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.
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.
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
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.
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!
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.
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!
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.
