There is a lot of power on tap with the 1,000-watt hub motor. Super73 will point out that the hub-motor's 1,000-watt rating is what's known as nominal, which means that is the continuous power it can deliver. It is also capable of delivering 1,500 watts peak, so it is quite quick. Using the LCD control screen, pedal assist level can be set to Eco, Mid, or High modes. Eco provides the lowest power and longest range. Mid delivers about 50-percent output (so roughly 500 watts) from the hub-motor while pedaling, and High gives full motor power while pedaling. The thumb throttle is always ready to go, and if you apply it while pedal assist is helping you, the throttle overrides pedaling. This throttle feature keeps the OG from being a Class 3 bicycle.
