A RIDE FEEL LIKE NO OTHER
VAAST Bikes is the first to use ALLITE? SUPER MAGNESIUM?, a true innovation in material science. This high-strength alloy features excellent shock absorption properties, weighs 33% less than Aluminum and 50% less than Titanium by volume, and is significantly stronger than both. Through the exclusive use of this eco-friendly metal, we have achieved a ride that feels like no other.

COMMITTED TO A VIBRANT CYCLING ECOLOGY
From the beginning we¡¦ve been inspired to promote the responsible use of materials and responsible riding in all its forms.
Our frames are more sustainably made and they¡¦re 100% recyclable. We were also the first bike brand to use 100% fiber-based, plastic-free packaging.
