There’s a certain charm in watching a child ride their first two-wheeler that mix of fear, focus, and freedom rolled into one grin under the helmet. Vida seems to have captured that exact emotion with its latest play in the electric mobility space: the DIRT.E K3. But this isn’t just another kids’ e-bike. It’s a cleverly engineered machine that grows quite literally with its rider.
A Bike That Grows with the Rider
At first glance, the DIRT.E K3 looks like a scaled-down dirt bike — compact, sturdy, and neatly balanced. But what makes it special is its adjustable sizing system. Vida has built the K3 around a modular frame that can expand as your kid does. In its smallest setup, it measures 1181 mm in length with a saddle height of 454 mm, perfect for a four-year-old who’s just learning to balance.
As they grow, the same bike stretches into Medium (1264 mm) and Large (1342 mm) configurations, with seat heights rising to 544 mm and 631 mm respectively. Even the wheelbase increases — from 751 mm to 834 mm to 912 mm — keeping the ergonomics consistent. In other words, no awkward riding position, no “outgrowing” the bike too soon. Smart move by Vida, especially for parents looking to justify the spend.
| Configuration | Length (mm) | Saddle Height (mm) | Wheelbase (mm) |
|---|---|---|---|
| Small | 1181 | 454 | 751 |
| Medium | 1264 | 544 | 834 |
| Large | 1342 | 631 | 912 |
Built to Handle Dirt, Literally
Underneath the friendly proportions lies some serious engineering. Vida’s Modular PDC frame, paired with 16×2.4-inch tyres at both ends, gives the K3 a stable stance. It’s been developed jointly by Hero’s German Tech Centre and the company’s Jaipur-based innovation hub — an interesting cross-continent collaboration that shows in the bike’s refined ride dynamics.
Power comes from a hub-mounted motor rated at 10A continuous and 20A peak, churning out about 0.68 hp and a punchy 39.1 Nm of torque. That’s more than enough to handle off-road trails, small jumps, and backyard adventures — all without intimidating the young rider. The torque delivery is linear, avoiding jerky acceleration. Think of it as training wheels for throttle control.
Cooling is handled via air, keeping things simple and reliable, while throttle response is electronically managed. Parents can breathe easy too — Vida’s companion app allows you to limit power and speed depending on your kid’s experience level.
Learning Through Modes
Here’s where the K3 gets practical. Vida’s split the performance into three riding modes — Beginner, Amateur, and Pro. Each mode corresponds to different top speeds:
| Mode | Approx. Top Speed |
|---|---|
| Beginner | 7–8 kmph |
| Amateur | 16–17 kmph |
| Pro | 23–25 kmph |
That means your child can start slow, build confidence, and move up at their own pace. And if things go wrong? There’s a magnetic lanyard kill switch — the moment it detaches (say, if the kid falls or steps off suddenly), power cuts instantly. A small but crucial safety feature.
Battery, Charging, and Everyday Practicality
The DIRT.E K3 uses a removable 48V NMC Li-ion 21700 battery pack with a 360 Wh capacity. Parents can pop it out easily and charge it at home. Vida includes a portable charger that tops up the battery from 20% to 80% in about two hours — fast enough for a post-lunch refill before the evening ride.
Full charge times vary depending on temperature, but the system is designed for convenience: standard 230V input, 4A output at 42V DC, and the usual 50 Hz frequency. Vida’s choice to skip a fast charger here is deliberate — slower charging means longer battery life, and for a product meant to last several years, that’s a wise call.
On braking, the K3 gets a 160 mm rear flat disc as standard, with the front brake available as an optional accessory. The lever’s size and reach are kid-friendly, and the system offers enough bite without being too aggressive. Tyres run at around 7 PSI, with flexibility for minor adjustments based on terrain.
Designed Like a Real Dirt Bike
Despite being built for kids, the DIRT.E K3 looks every bit the part. The silhouette echoes full-size off-road machines — short overhangs, raised seat, purposeful stance. The proportions remain consistent across all three size configurations, so even as the bike “grows,” it retains that proper motorcycle look.
Small design touches like the over-moulded wiring harness, soft-touch panels, and impact-absorbing side components make it feel premium. Vida’s colour palette — Red, Purple, and White — adds some flair without crossing into toy territory. It still feels like a “real” bike, which kids will love.
Pricing and Availability
Vida’s rolled out an introductory price tag of ₹69,990 for the first 300 units. Bookings are already open, and deliveries will begin January 15, 2026. Initially, availability will be limited to select dealerships across Delhi, Bengaluru, Pune, Jaipur, and Calicut — with a gradual rollout expected later in 2026.
Given that Hero MotoCorp backs the brand, after-sales support and spare availability should be a non-issue. Parents investing in the K3 are essentially buying into a few years of progressive learning and fun, wrapped in a well-engineered package.
Final Word
Vida’s DIRT.E K3 isn’t just another entry into the electric toy segment. It’s a carefully designed product that blends engineering finesse with emotional insight — acknowledging that kids don’t just want “safe” bikes, they want real bikes.
With its adjustable sizing, safety-focused design, and solid battery tech, the K3 could very well become the electric equivalent of the old Hero Ranger — a childhood classic in the making.
