COMMENCAL CLASH 20 PURE WHITE 2026
A proper full-suspension mountain bike for young riders
The COMMENCAL CLASH 20 is built for kids who already have a solid riding base and want a bike that feels much closer to a real enduro bike than a basic kids MTB. With 20 inch wheels, 120mm of front travel and 125mm of rear travel, it is designed to give younger riders more confidence, more comfort and more grip on proper trails.
This is the kind of bike that makes sense for kids who are progressing quickly and starting to ride steeper, rougher ground. COMMENCAL has built the CLASH 20 around lightweight-rider-specific kinematics, so the suspension stays active and supportive without feeling harsh or overdamped for smaller riders.

Why It Stands Out
The CLASH 20 stands out because it is not just a small mountain bike with rear suspension added on. COMMENCAL has put proper thought into how the bike works for lightweight riders, from the suspension tune through to the geometry and crank length.
The result is a kids full-suspension bike that should feel far more controlled and confidence inspiring on demanding trails than most bikes in this category. It is aimed at young riders who want to ride harder, faster and with more control as their skills improve.
