Abstract

Electric bicycles with mid-drive systems provide better weight balance and performance, particularly on uphill terrain. However, their production cost is generally higher than hub-drive systems, limiting accessibility for wider users. This study aims to develop a cost-effective mid-drive conversion system by modifying a hub-drive e-bike using a custom steel bracket and an integrated gearbox, and to evaluate its power performance and energy efficiency. The prototype was powered by a 60V 15Ah LiFePO₄ battery and tested under laboratory and road conditions, including no-load, flat-road, and uphill tracks (5°–15° slopes). Data were collected using a tachometer, GPS, and PZEM-015 module to record speed, voltage, current, and power consumption. The motor required 659 W during acceleration from 0–10 km/h, decreased to 183 W at 19 km/h, and increased to 867 W at 39 km/h. Under a 15° incline, the e-bike maintained 15 km/h with 1120 W of power. Distance-based tests (2.08–4.07 km) showed stable energy consumption between 21–26 Wh/km, increasing proportionally with rider weight. The gearbox-assisted mid-drive conversion improved torque distribution, transmission efficiency, and energy performance, providing a practical and affordable alternative for developing efficient electric bicycles.

Abstract

Desa Gedog Wetan memiliki karakteristik masyarakat yang mayoritas berwirausaha, seperti di bidang produksi tahu dan tempe, pandai besi, pembuatan sangkar burung, serta sektor pertanian. Meskipun sebagian warga telah menekuni usaha pembuatan sangkar burung, terdapat minat dari kalangan pemuda untuk mengembangkan usaha di bidang pengecatan sangkar yang masih minim pelaku. Namun, keterbatasan kompetensi dan keterampilan teknis menjadi kendala utama dalam mewujudkan peluang tersebut. Menanggapi permasalahan ini, tim pengabdian kepada masyarakat menyelenggarakan program pelatihan yang bertujuan untuk meningkatkan keterampilan pemuda dalam pengecatan sangkar burung. Pelatihan meliputi pengenalan alat dan bahan, pemilihan sangkar, teknik pendempulan, pengamplasan, hingga proses pengecatan dasar dan finishing. Hasil kegiatan menunjukkan bahwa peserta mampu menghasilkan kualitas pengecatan yang rapi dan halus, serta memiliki standar yang kompetitif dibandingkan dengan pelaku usaha yang telah ada. Program ini diharapkan dapat mendorong munculnya wirausaha baru di kalangan pemuda, meningkatkan daya saing produk lokal, serta memberikan dampak positif bagi pengembangan ekonomi masyarakat setempat.
