My latest ride, an A2B Metro that I call White Lightning. A large, powerful hub motor in the rear wheel accelerates this bike quickly to its governed speed of 20mph, with or without pedaling. Notable features include dual disc brakes and front/rear suspension. This is one swift, smooth riding bike. Cruising range on the hidden-in-frame battery is approximately 20 miles at full power. A second, optional battery fits under the rear rack, doubling the range.
