Designed for the Urban Jungle

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.

VAAST full carbon disk fork with fender
and rack mounts

Built for uptown, downtown, out of town, and back again


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.


Our exclusive use of Allite Super Magnesium results in a bike that is lighter, stronger, and profoundly better than those made with other conventional materials.


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 feel like no other.

  • Efficient power transfer makes for easier climbing
  • Shock absorption properties neutralize much of the road buzz
  • Frame weight rivaled only by Carbon Fiber


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.

The Model U/1 650b has been designed for what most people who venture out on a bike need. It is the unsung hero of the bike world: Fast, light, and nimble on all surfaces. Quick around your local bike trail, cool around the block, and rugged and durable on your gravel roads, fire roads and trail adventures. Its sporty geometry, vibration dampening materials, and wide, comfortable tires will eat up the miles wherever you take it. It is perfect for riders who want a comfortable do-it-all bike, packed with performance and multi-functionality.
