Here is some info on the Empulse RR:
The battery is load-bearing structural part of the frame, which is made of aluminum. It was made by Sapa in Portland, Oregon, and the welds are gorgeous. This bike appears solidly built. It rides on forks taken from a Triumph and reworked by Traxxion Dynamics. The rest of the hardware is equally nice: Brembo brakes, Carrozzeria forged aluminum wheels, Attack Racing adjustable triple clamps and a Works Performance shock.
