Why We Love It
The Union is Diamondback's speedy city slicker. This Class 3 (pedal-assist up to 28mph) e-bike will light-up the city streets with the powerful Bosch Performance Line Speed motor and 500Wh battery that keeps the party going for miles and miles. 27.5" wheels provide a comfortable and smooth ride and disc brakes ensure you're confident cornering and stopping even if the weather turns. Speaking of wet weather, Diamondback has your back with front and rear fenders to keep you clean as well as head/tail lights that light up your path and keep you seen from vehicles on the road. Bring all your essentials along for the ride with the rear rack capable of carrying panniers or simply bungee your backpack to the top to minimize unfortunate back sweat.
