The Urban Model U/1 exists to get you anywhere a paved route will allow you to go on a daily basis in a surprisingly comfortable way. Everything has been intelligently considered: weight reduction, more durable componentry, variable wheel size compliance, corrosion-proof inner and outer tube coating, and, most importantly, redefined superior fit and feel. These advantages have been carefully engineered into one bike to provide for a ride feel that will inspire you to skip the ride-share app and go it on two wheels, all day, every day.

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-damping 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.
