Skuter listrik adalah solusi untuk mengurangi konsumsi bahan bakar akibat meningkatnya jumlah pengguna sepeda motor dan terbatasnya pasokan bahan bakar fosil. Desain skuter listrik harus mempertimbangkan kinerja, kenyamanan, dan keamanan, dengan sistem pengereman menjadi penting untuk stabilitas dan keselamatan. Analisis termal dan struktural pada berbagai desain cakram rem menggunakan ANSYS menunjukkan bahwa model 3 adalah yang optimal dengan total fluks panas sebesar 1,0576 W/mm², suhu maksimum 126,79°C, tegangan von-Mises maksimum 62,269 MPa, dan deformasi total 0,018962 mm. Analisis kelelahan mengindikasikan bahwa model 3 memiliki kinerja terbaik dengan masa pakai kelelahan 1×10^7 siklus, kerusakan kelelahan sebesar 100, dan faktor keamanan 1,1788. Simulasi dinamis dengan ABAQUS menunjukkan bahwa model 3 mempertahankan suhu dan distribusi tegangan terendah dan paling stabil selama pengereman pada berbagai kecepatan. Analisis MATLAB SIMULINK menunjukkan bahwa meskipun desain cakram rem baru mempengaruhi jarak dan waktu pengereman, dampaknya tidak signifikan. Pada pengereman LBS, koefisien gesek yang lebih tinggi menghasilkan jarak dan waktu pengereman yang lebih panjang, sedangkan pada pengereman ABS, koefisien gesek yang lebih tinggi menghasilkan jarak dan waktu pengereman yang lebih pendek.
