Get it done.
The Class 3 Union 1 gets things done. Built on a sleek aluminum frame with internal cable routing, this e-bike is powered by a Bosch Performance Line Speed motor and a Powertube integrated 400Wh battery. The Bosch Purion on-board computer lets you focus on the important things with a minimalist design and with all the data you need at the touch of a button. A 10-speed Shimano drivetrain fine-tunes your pedaling, while Tektro hydraulic disc brakes keep your speed under control. Wide tires on 27.5-inch wheels take the sting out of rough pavement. With an integrated rack and fenders, the Union 1 lets you cut through city traffic with ease and confidence.
