The Effect of Reducing the Number of Transmission Mechanisms in Electric Motorcycle Conversion on Energy Consumption.

Abstract

This study examines the effect of reducing the number of transmission mechanisms on electric motorcycles on
energy consumption by using a transmission ratio of 0.8 on flat roads. In the study, conventional motorcycles
(CE) have been converted to operate on batteries. With the transmission mechanism still connected to the chain
then transmitted to the flywheel and transmitted to the primary sheave. Of these three mechanisms, there is a
drawback, namely quite large vibrations. This study reduced the number of transmission mechanisms. This test
was carried out on a flat road with a distance of 5 km and a speed of 30 km / h (kept constant), with variations
in speed settings, and two variations of loads (70 kg and 140 kg) at a distance of 5 km. The results showed that
the lowest power consumption was achieved with speed setting I and a load of 70 kg at 0.027 kWh / km. This
study shows that reducing the number of transmission mechanisms can reduce energy consumption and improve
the speed performance of electric motorcycles that are converted to increase.
