A Bosch Performance Line Speed motor powers the Diamondback Union 1, a Class 3 drive e-bike that offers pedal assistance up to 28 mph. A Bosch PowerTube 400 battery is hidden in the downtube of the aluminum frame, which also has internal cable routing, discrete branding, and a matte finish.
The Union 1 is a solid performer. This is made possible in part by the 27.5-inch wheels and wide 2.4-inch tires, which offer stability and traction on a variety of surfaces. Additionally, the through-axles on the front and rear wheels make for stable, quick handling.
The rear derailleur and 10-speed Shimano Deore cassette handle the shifting. The set is completed by Tektro hydraulic disc brakes, fenders, a kickstand, and a supportive but sporty saddle. The battery range claimed by Diamondback is 35 to 55 miles, which is more than enough for the majority of daily commutes and rides.


If you’re looking for a commuter-friendly e-bike, take a look at the Union 1. In this article, we’ve analyzed reviews to help you make a decision!

Diamondback Union 1

The Union 1 is a great addition to the Diamondback line with its stellar performance and some amazing commuter-friendly features. However, for someone who is new to e-biking, it might be a bit difficult to get into muscle memory because of its heavy weight and some budget-minded components.

Minor glitches aside, the more I rode the Union 1, the more I appreciated its appeal as an alternative to my car.
