Why We Like The Union 1 e-Bike

Whether we're zipping through a long work commute, or enjoying a peaceful cruise on scenic backroads, we opt for the Diamondback Union 1 because it's both fun and practical. This class 3 e-bike offers powerful pedal assistance at speeds up to 28mph, allowing you to cover some serious ground in a matter of minutes. Voluminous tires make for a comfortable and stable ride, while the hydraulic disc brakes ensure you can keep your speed safely in check. Not to mention, the bike comes pre-equipped with fenders, a cargo rack, and a kickstand, meaning you're equally ready for long tours as you are for quick trips to the store.

Best Cruiser Bike

Familiarity:
I've used it several times
Size Bought:
M
Height:
5' 6"
Weight:
130

I am a mom of two small kiddos (F, 5?6?, 130lbs). I got a size M to pull my 70lb Burley bike trailer with our kids and baggage that goes with small kids. It pulls like a DREAM. We live in a hilly area and I can easily adjust the bike assist to go up and down each hill. It?s been the best purchase so far of 2021!
