The drivetrain—we’re happy to report—has little drive lash. As electric-powered vehicles deliver 100 percent torque at zero rpm, e-bikes often wrench on their final drive, causing jerky power delivery. The Vectrix exhibits little of this, thanks to a couple of steps. First, the motor is actually attached to the rear hub itself, thus reducing the number of moving parts; second, the Vectrix’s software applies a progressive power curve to the torque delivery. It’s not as quick off the line as it might otherwise be, but definitely smooth.
