  The RFN Warrior Pro SX-E15 is RFN's flagship motocross-focused electric dirt bike.

  Designed for riders progressing beyond traditional youth bikes, the SX-E15 combines a massive 21kW peak output motor, 650Nm of torque and a lightweight race-focused chassis to deliver explosive acceleration and serious off-road capability. RFN positions the bike directly against traditional 85cc motocross machines while offering the smooth power delivery, reduced maintenance and instant throttle response that electric riders love.

  Powered by a 74V 40Ah Samsung lithium battery, the SX-E15 offers impressive range, fast charging and a hot-swappable battery system, making it equally at home on motocross tracks, practice facilities and private off-road land.

  My Take as a British MX Rider

  The SX-E15 is where RFN stops competing with youth electric bikes and starts competing with proper motocross bikes.

  At over 20 horsepower, 650Nm torque and 60mph capability, this thing is seriously quick. What impressed me most is how light it remains compared to many petrol alternatives. That gives riders better cornering, less fatigue and a bike that feels much easier to throw around.

  If you're looking for a genuine alternative to an 85cc motocross bike, the SX-E15 deserves to be on your shortlist.
