Common questions
How much does the RFN Warrior Youth SX-E5 cost in Australia?
The RFN Warrior Youth SX-E5 is listed at $4,990 (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-E5 road legal in Australia?
Not as a bicycle. The RFN Warrior Youth SX-E5 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-E5?
The RFN Warrior Youth SX-E5 has a claimed range of about 40 km from its 1200Wh 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-E5 have?
The RFN Warrior Youth SX-E5 uses a RFN motor, 5kW peak motor, in a mid-drive position, producing 145Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the RFN Warrior Youth SX-E5 weigh?
The RFN Warrior Youth SX-E5 weighs about 47 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-E5 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.
