Which RFN fits you?
RFN sizes its bikes by rider height. The compact Warrior bikes are first bikes for small riders. The Warrior SX-E8 and Warrior Pro SX-E15 are race-style dirt bikes, and the Ares bikes are built for long trail rides.
How to choose: Measure the rider first: each card gives the height RFN sizes that bike for. Then pick by riding: a Warrior for dirt and tracks, an Ares for distance.
