Union 1
The Class 3 Union 1 electric bike gets 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 integrated 400Wh battery. The Bosch Purion on-board computer lets you focus on the important things with a minimalist design but 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.

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.

There was a time when every guitar was an acoustic and it was good. Musicians got what they needed out of their instruments, and with the right group, it even rocked a bit. But then the guitar got electrified and, just like that, everything changed. Jimi. Eddie. Slash. The world would never be the same. And now, yet again, thanks to the ebike, riding will never be the same. Because what was a world of acoustic riding is about to become a world of nothing but high-fives, smiles, and maybe a few horns \m/.
