This mountain bike was fully designed and developed at the B'Twin Village (Lille, France) and is the brainchild of an expert team of all-mountain bike enthusiasts.
The Rockrider team designed and tested this Rockrider AM 100 S All-Mountain bike together with their MTB testers in the Vosges and the Alps.

The AM 100 S is assembled at our own factory in Lille, just steps away from the bike design team.
