JUNIOR

What's more lovely than the childhood memories? Ouch! Perhaps the one that crosses your mind right now is that first scar that you got while riding on a bike! But hey, it was also a lovely family time, the first taste of courage to learn how to get back on after falling off, and go on adventure with new friends. So, go get bikes for your kids, and see those beautiful things also happen to them.

EXCEED YOUR EXPECTATIONS

Unbelievably capable for any XC trails
Big thanks to modern geometry; a slacker head angle and longer reach and steeper seat, makes the Polygon Siskiu D series series unbelievably capable for riders looking to tackle XC riding with some aggression. The anti-squat has been optimized for pedaling performance and the suspension is more progressive for when the trail gets rowdy. We improved support under power, enabling Siksiu D platform climbs like a hardtail without substituting comfort or traction. The downs are even better when you enjoy the climb up.
CROSS COUNTRY ?
CROSS COUNTRY ?
We understand how mesmerizing mountains are and everything in it; the scents through the wind, the rocky climbs and descents, and the singletracks. So we built you bikes that keep you rolling on cross country to technical tracks. Faster to feel the wind and smoother to beat trails. Are you ready to be mesmerized more? See more...
