Standout strength
8kW peak and 270Nm with a 60V 35Ah Samsung battery and long-travel suspension at 58kg.
The main compromise
Range is a claimed 60km at 35 km/h, and it is still an off-road motorbike.

Check before you buy
Confirm where you can legally ride it (private land or a registered off-road park), and who handles warranty and parts in your state.

Common questions
How much does the RFN Warrior Youth SX-E8 cost in Australia?
The RFN Warrior Youth SX-E8 is listed at $5,990 (RFN Bike Australia price.). eBikeFinder checks pricing against manufacturer and distributor information, and prices can change with sales and stock. This price was last checked on 9 Oct 2026.
Is the RFN Warrior Youth SX-E8 road legal in Australia?
Not as a bicycle. The RFN Warrior Youth SX-E8 sits outside the 250W pedal-assist standard (through higher power or a throttle that drives it beyond walking pace), so in Australia it is treated as a motor vehicle. That means it is for private property or off-road use, not public roads or shared paths, unless registered.
What is the range of the RFN Warrior Youth SX-E8?
The RFN Warrior Youth SX-E8 has a claimed range of about 60 km from its 2100Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the RFN Warrior Youth SX-E8 have?
The RFN Warrior Youth SX-E8 uses a RFN motor, 8kW peak motor, in a mid-drive position, producing 270Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the RFN Warrior Youth SX-E8 weigh?
The RFN Warrior Youth SX-E8 weighs about 58 kg. That matters if you need to lift it onto a car rack, carry it up stairs, or store it, since e-bikes are heavier than regular bikes because of the motor and battery.
Who sells and backs the RFN Warrior Youth SX-E8 in Australia?
The RFN range is distributed in Australia by RFN Bike Australia. Buying from a brand with real Australian support matters most when something needs a warranty claim or a service.
