Meet the RFN Warrior SX-500W — the perfect step-up bike for Little Rippers who’ve outgrown their Electric Balance Bike and want something that actually feels like a mini dirt bike. This thing delivers real suspension, real brakes, and real moto control, all while staying lightweight enough for younger riders to handle.

We’ve tested a ton of kids’ electric bikes in the shop, and the SX-500W hits a sweet spot: fast enough to make the kids grin, controlled enough to keep parents comfortable, and durable enough to take the beatings that come with learning to ride, all without breaking the bank.

500W Brushless Power (That Kids Can Actually Control)

The Warrior uses a strong 500W brushless gearbox motor paired with a 36V 7.5Ah lithium battery. It hits hard, but RFN gives you three speed modes so you can dial it in:

Mode 1: 15 km/h (9 mph)
Mode 2: 25 km/h (15 mph)
Mode 3: 35 km/h (21.7 mph)

It’s quick, responsive, and super smooth thanks to the sine-wave controller. And yes — the battery is swappable, so you can grab a spare and double the ride time.

14” Alloy Wheels + Real Suspension = Real Stability

The SX-500W isn’t a balance bike frame pretending to be a moto. It’s a legit mini-moto chassis with:

Front & rear suspension
14x2.4" all-terrain tires
Lightweight alloy wheels
Low center of gravity

Kids get better confidence, better cornering, and a way easier time riding on dirt, grass, or hardpack.

Hydraulic Disc Brakes (Front & Rear)

This is immediately where it destroys Superbolt, Super73, and half the budget Amazon bikes:

Front hydraulic brake
Rear hydraulic brake
Bigger, moto-style rotors

Your Little Ripper actually gets stopping power — not a squeaky drum or a barely-there cable brake.

Sized Perfect for Ages 4–7

Seat height comes in at 490mm (19.3"), which sits right between a typical 16 balance bike and a true 50cc bike. If your kid isn’t ready for a gas bike yet, this is exactly the gap this bike fills.

Ride Time & Battery System

Expect 45–75 minutes depending on the speed mode and terrain.
The battery slides out with a simple release tab, making swaps fast and kid-friendly.

Charging time: 2.5 hours with included 3A charger.

Durability Built In

The Warrior uses a tough steel frame, reinforced swingarm, and a simple wiring layout that makes it easy for parents to maintain. RFN actually supplies dealers with full parts support and a 1-year warranty on the motor, controller, and battery.
