Nice hunt @azwarrangkuti. Top speed of 52 mph practically makes it as fast as a 150cc petrol scooter. Now that is really good. I dont know the usual top speed for ebikes, but i doubt its usually this high. At 1500 dollars, it a great alternative for office goers who ride a bike or scooter but want some exercise on the way. I see how useful and practical this bike can be.
