Vaast U/1 Street 650B Urban Bike

The U/1 650b model is designed for most biking adventures. It's the unsung hero of the cycling world: fast on all surfaces, light and agile handling. Speed on bike paths, catch the eye of passersby, and be tough on gravel, off-road, and country trails.

Its sporty geometry, shock-absorbing materials and wide, comfortable tires make it easy to ride wherever you go. For the cyclist who wants a comfortable ride, great performance and versatility.

LIGHTER, STIFFER, PROFOUNDLY BETTER.

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.

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.

COMFORTABLE AND SPORTY

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.
