WE CHECK THE FIT
We help check rider fit, experience level and intended use if you need guidance choosing the right kids bike.
PERFORMANCE
POWER, CONTROL AND CONFIDENCE
900W peak power, 50 Nm published torque and three selectable speed settings up to 21.5 mph on a larger 16-inch chassis.
The right kids bike should feel manageable, confidence-building and appropriate for the rider.
RIDER FIT CHECK
BEST FOR
Progressing young riders around 120–140 cm tall, age 6+, who have outgrown the smaller RFN Warrior Kids models.
CHECK FIRST
Very small beginners who need the lower SX-E400/SX-E500, or taller riders ready for the Warrior Youth range.
NEXT STEP
Ask MotoEbikes about sizing if you are unsure which kids bike is the better fit.

CHECK FIRST
Rider weight, terrain, speed mode, temperature and harder riding can all reduce the real-world range.

Think about how long a normal riding session will be and how easily the bike can be recharged before the next one.
