Kids have a knack for growing up fast, and it’s just a fact of life. Vida unveils Acro electric dirt bike, designed with this exact problem in mind. They outgrow their shoes, their clothes, and, of course, their expensive toys.
With the huge rise in popularity of electric motorcycles and dirt bikes, the industry finally started making proper scaled-down versions for children. But here’s the thing: buying a motorized bike for a kid has a major flaw. Those little ones will outgrow whatever vehicle you get them in no time.
You end up spending a fair amount of money on a ride that only lasts a year or two before it’s too small. Fortunately, a team called Vida has found a brilliant way to solve this costly problem.
Meet the Vida Acro (Also Known as the K3)
Vida calls this machine the Acro, but you might also hear it referred to as the K3. Regardless of the name, it’s a remarkable piece of engineering.
What makes this e-dirt bike so special is its ability to physically grow with your child. In fact, it could even work for some smaller adults looking to have a bit of fun.
This growth feature is achieved through a clever mechanical design. At the heart of the Acro is a frame that can actually extend and contract to fit the rider who’s taking it for a spin.
While a lot of people noticed this bike at a recent CES show, Vida has been showcasing this design since around 2024. It even went on to win the prestigious Red Dot Award in 2025. Honestly, I completely agree with the judges, and this bike definitely deserves the recognition it’s been getting.

The Magic of the Extending Frame
So, how do you actually make a dirt bike grow? The frame and fork are built around a clever three-point adjustment system. This system impacts everything from the wheelbase to the stand-over height, but interestingly, it doesn’t change how far you reach to the handlebars.
The body panels, fairings, seat, and handlebars don’t shift at all. Instead, it’s the front fork and rear swingarm that do all the adjusting.
If you focus on the swingarm where it connects to the foot pegs, you’ll see a silver-like arm with an orange knob on top. There’s also a shock right behind it. This is where the real magic of adjustability takes place.

How the Adjustment Actually Works
Start the adjustment process by turning that orange knob with a tool. You’ll also need to adjust the rear shock, which is accessible through a tiny orange window just behind the fairing.
With these adjustments, you can effortlessly raise the main body of the bike. The rear wheel and the weight at the back help keep the bike grounded while the front lifts up.
You’ll definitely want to loosen the front fork before you start the raising process. The front and rear work together to stretch the bike out. But I can’t help but think… there’s no way you could just lift the front and ride it like a chopper. Seriously, don’t try that at home!
There’s a useful video out there that shows the shock rotating as the bike goes up and down through its three settings. The lowest setting gives you a 751 mm wheelbase, and the middle stretches it to 834 mm. The final position maxes out at 912 mm, which also provides the highest stand-over height.
This extensive range of adjustments allows the bike to comfortably accommodate kids from ages 3 all the way up to 9 years old.

Performance and Tech Specs
So, why would a manufacturer decide to include such a cool feature in their product? Well, it’s pretty straightforward. Parents can invest in just one ride that will keep their child engaged for much longer than a couple of years. That’s bound to attract a lot of adventurous families!
Now, let’s get into the tech that makes this all possible.
It’s important to keep in mind that this is designed to be your child’s very first e-dirt bike. It’s essentially a training bike, which means it has a top speed limited to 25 kph (15.5 mph), and you can only hit that speed in the third and final setting.
At first, that speed might not impress you much. But remember, this is meant to be an introductory machine. It provides just the right amount of power to enjoy the thrill without going overboard.
This also means we can’t really expect top-tier, adult-level equipment. Curiously, Vida’s global website doesn’t say anything about the continuous power the motor can produce. What we do know is that it has a hub-mounted motor, so there are no chains or belts to maintain.
Thankfully, I found out that depending on where you are in the world, the system can offer up to 500 watts of peak power.
In terms of range, Vida highlights a 360 Wh battery pack as the source of power. However, they don’t provide any details on how long that battery will last. I can confidently say it’s likely less than an hour of continuous riding.
But for a toddler, that’s probably more than enough to hold their attention.

Weight, Brakes, and Parental Control
Throw on a rear disc brake and a simple thumb throttle, and the Acro really starts to feel like a complete package. One of the best parts? The app control. Parents can connect to the bike through a smartphone app, allowing them to keep tabs on settings and even limit speeds if needed.
All this tech adds up to an electric vehicle that weighs just 22 kg (48.5 lbs). According to Vida, that’s lighter than some electric mountain bikes from those big-name brands.
It’s a pretty decent weight for teaching your little thrill-seeker how a powered bike feels. And if they drop it, you won’t have to worry about hurting your back trying to lift it back up.

Why Riding Camps Will Love This Bike
Not only do parents finally have a ride that adapts to their child’s growing abilities, but there’s also a significant advantage for businesses.
Picture a dirt bike riding camp or a rental facility. Typically, you’d need a whole fleet of various-sized dirt bikes to accommodate all the kids that show up. But with the Acro, one bike can be adjusted to fit different sizes. This drastically reduces the number of dirt bikes cluttering your track.
Plus, the removable battery packs mean you can charge them in your office, which helps clear up space in your business and keeps your warehouse neat and tidy.
Price, Availability, and the Catch
So, how much should you expect to pay for this impressive machine? According to Vida’s global website, the Acro comes in at 69,999 INR, which is about $775 (€665 with the current exchange rates).
When you factor in that it’s a bike designed to last six years, that’s a pretty enticing reason to look at the K3.
Also, consider the strong support behind the brand. Vida emerged from Hero MotoCorp, meaning they have a distribution network that spans 48 countries. They’re well-equipped to deliver these bikes to riders everywhere.
However, there seems to be a bit of a snag. I actually tried to go through the process of buying a K3 to see how it all worked. It didn’t take long for me to realize that I could only place an order if I was living in a handful of select cities in India or in certain countries in Europe.
If you’re in the United States, you can’t just click and buy one right now. You might need to reach out to Vida directly to inquire about importing it. Alternatively, you could look for a third-party distributor who’s willing to bring a K3 into the States. Just be prepared to pay a bit extra to get it shipped across the ocean.
Who knows, maybe in the future, Vida will officially launch the Acro in North America. Until then, it’s a fantastic idea that’s just a bit out of reach for some.
