  The RFN Warrior Pro SX-E8 is built for serious young riders who are ready to step beyond traditional youth electric bikes.

  With a powerful 6kW electric motor delivering up to 13.5kW peak output, a large 2100Wh lithium battery and race-inspired chassis geometry, the SX-E8 offers the performance, control and durability needed for advanced off-road riding and motocross progression.

  Designed as a genuine alternative to a 65cc petrol motocross bike, the SX-E8 combines impressive speed and torque with the quiet operation, instant throttle response and low maintenance benefits of electric power.

  My Take as a British MX Rider

  The SX-E8 is where RFN starts entering proper motocross territory.

  At 13.5kW peak output and 85km/h capability, this is no longer a stepping-stone bike. It has enough performance to genuinely challenge small-capacity petrol motocross bikes while remaining easier to ride thanks to its smooth electric power delivery.

  The combination of long wheelbase geometry, adjustable suspension and strong battery capacity gives riders a platform that can be ridden aggressively while still remaining predictable and confidence inspiring.

  If your rider has outgrown bikes like the SX-E5 and wants a serious motocross-style electric bike, the SX-E8 makes a huge amount of sense.
