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.
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 STACYC, 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 pit bike. If your kid isn’t ready for a gas bike yet but needs more than a … 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. And unlike Orion, RFN actually supplies dealers with full parts support and a 1-year warranty on the motor, controller, and battery.
