Union 2
The Class 3 Union 2 electric bike is fully loaded to get things done. Built on a sleek aluminum frame with internal cable routing, this eBike is powered by a Bosch Performance Line Speed motor and a Powertube 500Wh battery. The Bosch Kiox on-board computer provides ride data at your fingertips via a handlebar remote and easy-to-read color display. The Kiox is compatible with Bluetooth heart-rate monitors for the ultimate smart eBike experience. A 10-speed Shimano drivetrain fine-tunes your pedaling, while Shimano hydraulic disc brakes keep your speed under control. Wide tires on 27.5-inch wheels take the sting out of rough pavement. With built-in lights, an integrated rack, and fenders, the Union 2 lets you cut through city traffic with ease and confidence.

There are so many factors that determine your eBike’s range: the size of your battery, the level of motor assist you select, and how much weight you are carrying. Going uphill uses more battery than a flat trail.
To help you figure out the most accurate range estimate for your eBike, please try using Bosch’s range finder tool.
