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.


The Urban Model U/1 was designed for what most people who venture out on a bike need. The U/1 is fast, light, and nimble on all surfaces.


The U/1 exists to get you anywhere a paved route will allow you to go on a daily basis in a surprisingly comfortable way. When equipped with 650b wheels and tires it’s also a capable bike on gravel roads, fire roads, and suitable for other light trail adventures.
