Flytraks K2 Hoverboard Go-Kart Kit: The Easiest Way to Make a Hoverboard Family-Friendly
April 1, 2022
There’s a special kind of EV joy that comes from taking something you already own and turning it into a totally different ride. That’s exactly the vibe with the Flytraks K2 Hoverboard Go-Kart Kit.
I strapped it onto my hoverboard, tightened everything down, and took it out for a proper first ride. The end result feels like a “sit-down hoverboard” with way more confidence than standing—especially if you’re someone who’s always been a little uneasy on a balance board.
What you’re really buying
The Flytraks K2 is a frame, seat, and control setup that lets you drive a hoverboard like a low go-kart. Your hoverboard becomes the drivetrain. The kit clamps on using straps and textured pads, and you steer/brake using two hand levers.
It also comes with a little safety flag, which is a nice touch considering how low you sit to the ground.
Unboxing vibes: surprisingly beefy
Right out of the box, the first thing I noticed was how sturdy the main wheel and frame felt. It has that “heavy duty” feel you want from something that’s going to take repeated curb hops, driveway bumps, and kid-level chaos.
You get the seat, hardware, straps, footrest pieces, the steering handles, and the suspension parts.
Assembly: doable, but the manual didn’t help much
I’ll be honest: the user manual wasn’t very clear. I was still able to figure it out, but it took more common sense than instructions.
A few install notes from my build:
Tools: It includes tools, but I used my own Allen keys plus socket wrenches (13mm and 17mm) to make it easier.
Keep bolts loose at first: I left everything a bit loose until the full frame was together, then tightened it down.
The shock install is the fiddliest part: Getting the suspension lined up can feel awkward. If the shock angle is fighting you, loosening the center section gives you enough play to get the holes aligned.
Seat and straps are straightforward: The seat bolts on with washers against the plastic. The hoverboard straps are Velcro and you’ll want them very tight.
Once it was assembled, attaching the hoverboard itself was simple. I made sure the hoverboard was oriented correctly (front side with the power/charging side positioned properly), centered it on the pads, then cinched both straps down hard.
Dialing in fit: it actually adjusts
The front bar length is adjustable, which matters more than I expected. You can set it longer or shorter depending on height and comfort. That adjustment changes how natural the steering handles feel in your arms.
The suspension also has an adjustment you can twist to compress the spring more or less depending on rider weight, which is helpful if you’re swapping between a kid and an adult.
First ride: faster than it looks
The first time I powered up the hoverboard, it immediately started self-balancing like normal—which feels a little wild when it’s strapped under a kart frame.
Then I started rolling… and yeah, it’s definitely a lot faster than it looks sitting still.
Steering and braking feel
This style of kart control takes about five minutes to “get.”
Braking: You need to pull both handles for a full brake.
Turning: You can do sharp turns by pulling one handle relative to the other.
Reverse: Yes, you can go backward, but it takes a little practice to do it smoothly.
Once it clicks, it’s ridiculously fun. It’s the kind of ride that makes you keep looping the block just because.
Where it rides best
On smooth roads and clean pavement, it feels great—stable, playful, and easy to control.
If you head off smoother surfaces, the dual shocks are there to help take the edge off vibrations. You still feel bumps (you’re low to the ground), but it’s less harsh than a totally rigid setup.
Who this is for
This kit makes a hoverboard easier to enjoy for more people.
If standing on a hoverboard feels sketchy, sitting down makes it way more approachable.
Kids are going to love it, but speed is the big watch-out. It can get moving quickly, and younger riders may not be ready for how fast it accelerates.
It’s also a solid “throw it in the trunk” EV toy—easy to bring to a park, a cul-de-sac meetup, or a family hang.
What We Like
Turns a hoverboard into a more confidence-inspiring sit-down ride
Feels sturdy and heavy duty once assembled
Adjustable length helps fit different riders
Dual shocks help take the sting out of rougher surfaces
Genuinely fun, and surprisingly quick
Easy to toss in a trunk for family use
Things To Consider
The assembly manual isn’t very clear (expect to improvise)
Suspension alignment can be a little finicky during installation
It’s faster than many people expect—especially kids—so supervision and a safe riding area matter
Best experience is on smooth pavement; rough ground is still rough, just more manageable
Final Thoughts
After building and riding the Flytraks K2, I get why these hoverboard kart kits are so popular. It’s an affordable way to stretch the fun out of a hoverboard you already own, and it lowers the learning curve for anyone who’s hesitant to balance while standing.
If you want something compact you can share with the family—and you’re okay with a slightly DIY assembly experience—the Flytraks K2 is a really satisfying upgrade.
