XTRADA 20: Adventure Starts Here
Junior | 80mm Suspension | ALX Alloy | 20" Wheels
The Polygon XTRADA 20 is the perfect platform for building confidence and heading on off-road adventures.
The design is specifically for the ergonomics and power of younger riders, and we've added youth-specific components that prioritize ease of use and total riding comfort. By matching the bike’s proportions to a developing rider’s reach and weight, the XTRADA 20 removes the struggle of handling a heavy machine and replaces it with how a bike should feel.
