Your Whippet has three power levels to allow you to choose the best one to suit road conditions, as well as how strong you are feeling. Power level one will gently assist you along and at the same time will save battery power to maximise your range. At the other end of the scale power level 3 will give you maximum assist to help you up steep hills and push you through headwinds. In between is power level 2 to give a balance of battery charge economy to level of assist. The power level is simply selected by pressing a button on the handlebar control. Unlike some ebikes, you can do this at any time, either when you are stationary or cycling along. In the same way you can also change the power level whilst cycling along. Because your Whippet is so light and well equipped you can enjoy cycling it without any power assist at all - this is the ultimate economy mode of course, to extend your range even further!
Of course you can further control the speed of the eBike by using the derailleur gears.
