The effect of weight, speed, and mileage on the use of electric bicycle batteries

The use of electricity as a energy source for transportation media is developing. An electric bicycle is a simple transportation media that uses electric propulsion energy. The weakness of electric bikes is that the battery tends to damage due to use or age. In the market, many battery manufacturers provide alternative battery replacement products for electric bicycles. This study compares the performance between standard batteries obtained from electric bikes and aftermarket batteries sold widely. This research method is a field test with treatment on load and speed variations. The results obtained are the working voltage of aftermarket batteries is 4.4-4.6% smaller at speeds of 10 and 20 km/h, while at speeds of 30km/h, the voltage is relatively the same. For the current at 10km/h, aftermarket batteries have a smaller current of up to 2.6A, but at a speed of 30km/h, the current increases to more than 14A. While the average mileage of an electric bicycle battery is 10-32Km, on an aftermarket battery, it is between 9-35km.
