The NgebUTS electric bike is one of the vehicles developed by the Sumbawa University of Technology that makes this bike one of the innovations in providing environmentally friendly transportation facilities. Riding the NgebUTS NTB 1 electric bike for an extended period can cause health problems such as Low Back Pain. This study aims to obtain a good evaluation and recommendation for riding an electric bike NTB 1 and a design for an NTB 1 racing electric bike that is more comfortable and safe. The NgebUTS NTB 1 electric bike development uses a Universal Design approach, an analysis of riding posture using the REBA method, and a strength test on the frame using a simulation finite element method. As for the results of cycling posture analysis, lower cycling postures are better in the form of an angle body recommendation for the neck, torso, upper arm, forearm, and foot are 0°, 0°, 20°, 94 °, and 70°. These are obtained from changes in a bike frame by shortening the size of the bike and modifications to the handlebars by increasing that size. The test results on a bike frame with finite element analysis obtained a displacement value of 0.087 mm and a safety factor value of 4.157 ul, which means the mainframe prototype design is solid and safe to use. With the development of the NgebUTS NTB 1 electric bike, it is hoped that bike users can feel comfortable and secure, reducing the injury risk.
