Arctic Leopard Z Kids Electric Dirt Bike Lineup: Full Specs, Sizing Guide, and Which Model Fits Your Young Rider

If your kid has been begging for an electric dirt bike, you have probably noticed that the market is full of toy-grade machines that fall apart after a few weekends. The Arctic Leopard Z line is built differently. These are real electric off-road bikes designed by a manufacturer that also builds the EXE 880, one of the fastest electric dirt bikes on the planet. That engineering DNA trickles down into the kids lineup, and it shows.

The Z series currently includes four models: the E·20 Z, E·20 PRO, E·Z PRO, and E·16Z. Each one is sized and tuned for a different stage of a young rider's progression. Below, we break down the real factory specs, explain the key differences, and help you figure out which Z model is the right fit.

Arctic Leopard E·20 Z Specs: The Entry Point

The E·20 Z is where most families will start. It is the most accessible bike in the Z lineup, built around a 48V 13Ah battery pack using 3C-rated cells. That battery feeds a hub-direct-drive motor producing 1,000 watts of peak power and 50 Nm of torque. For a kids bike, those are serious numbers.

Three speed modes let parents dial in the right level of performance as confidence grows. Low mode caps the bike at 20 km/h (about 12 mph), medium opens it up to 30 km/h (19 mph), and sport mode tops out at 40 km/h (roughly 25 mph). That kind of adjustability means a cautious 8-year-old and a confident 12-year-old can ride the same bike at very different levels.

E·20 Z Key Numbers

• Weight: 28 kg (62 lbs) including battery
• Peak Power: 1,000 W
• Torque: 50 Nm
• Top Speed: 40 km/h (25 mph) in sport mode
• Battery: 48V 13Ah, 3C cells
• Charge Time: 60 to 90 minutes
• Range: Approximately 20 km (12 miles)
• Tires: 20 x 2.8 inch on spoke wheels
• Suspension Travel: 100 mm
• Seat Height: 72 cm (28.3 inches)
• Wheelbase: 98.5 cm (38.8 inches)
• Dimensions: 1450 x 780 x 950 mm
• Colors: Blue/white, black/yellow

A 60-to-90-minute charge time is a standout feature. Most competing kids bikes take three to five hours to recharge. With the E·20 Z, your kid can ride a full session, plug in over lunch, and be back out in the afternoon.

Stepping Up: The E·Z PRO

For riders who have outgrown the E·20 Z or want something closer to a real motocross feel, the E·Z PRO moves to a chain-driven drivetrain. That shift from hub drive to chain gives the bike a more traditional power delivery, with better torque transfer to the rear wheel during hard acceleration and climbs.

The E·Z PRO bumps the battery to a 48V 20Ah pack, a significant increase over the E·20 Z's 13Ah unit. More capacity means longer ride sessions and more consistent power output as the battery drains. The speed modes also shift upward: training mode runs at 25 km/h (16 mph), advanced mode at 35 km/h (22 mph), and sport mode reaches 45 km/h (28 mph).

E·Z PRO Key Numbers

• Weight: 46 kg (101 lbs) with battery
• Top Speed: 45 km/h (28 mph) in sport mode
• Battery: 48V 20Ah
• Drive: Chain
• Dimensions: 1470 x 650 x 910 mm

At 46 kg, the E·Z PRO is a more substantial machine. It feels closer to a scaled-down adult bike than a kids toy. That extra weight also comes with a sturdier frame built to handle drops, jumps, and rougher terrain as your young rider progresses.

The Full Z Lineup at a Glance

Between the E·20 Z and E·Z PRO sit two more models. The E·16Z uses 16-inch wheels for smaller or younger riders who are not quite ready for a 20-inch platform. The E·20 PRO splits the difference between the base E·20 Z and the full E·Z PRO, offering upgraded components on the same 20-inch wheel size. Together, the four bikes cover a wide range of ages, sizes, and skill levels.

How to Pick the Right Z Model for Your Kid

Start with seat height and wheel size. If your child can flat-foot the ground (or close to it) on a 72 cm seat, the 20-inch models are a good fit. That typically means riders around 4'2" to 5'2" tall. Younger or shorter kids should look at the E·16Z with its smaller wheels and lower standover height.

Next, think about experience. A first-time rider benefits from the E·20 Z's hub-drive simplicity. There is no chain to maintain, the low-speed mode keeps things manageable, and the 28 kg weight is light enough for a child to pick up after a tip-over. Once they are clearing small jumps and asking for more speed, the chain-driven E·Z PRO gives them room to grow without needing a completely different bike.

Finally, consider ride time. The E·20 Z's 13Ah battery with its fast 60-to-90-minute recharge is ideal for backyard and neighborhood sessions. If your kid is spending full days at a track or trail, the E·Z PRO's larger 20Ah pack will keep them riding longer between charges.

Why the Z Line Stands Out in a Crowded Market

The kids electric dirt bike space is growing fast, but most of what is out there falls into two categories: cheap toys that break and overpriced machines that are too powerful for young riders. The Arctic Leopard Z line occupies the middle ground that actually makes sense. Real off-road components, meaningful speed progression through ride modes, and the same factory behind the adult Arctic Leopard bikes that serious riders trust.

Every Z model uses a 48V electrical platform. That matters because it means genuine performance, not the watered-down output you get from 24V or 36V kids bikes. And with 1,000 watts of peak power available, these bikes have the headroom to handle hills, soft terrain, and the kind of riding that actually teaches kids how to ride.
