The power backbone of Leoguar electric bike is its professional permanent magnet synchronous motor system, up to 1200W in maximum power and a steady continuous output power of 750W, 50% higher than the industry standard (500W). Approved by the German TUV Rheinland laboratory, this motor produces 120N·m torque when it is loaded to 120kg and maintains a climbing speed of 18km/h at 15° slope, 28% higher than the Performance of the same category of Bosch Performance Line CX motor. Its IPM (Inbuilt permanent magnet) technology increases the power density to 4.2kW/kg. The motor efficiency curve shows that the energy efficiency is always ≥92% over the speed range 20-50km/h, far superior to the 82% efficiency threshold of traditional hub motors. In the 2023 Alpine Cycling Challenge, the Leoguar electric bike with this motor rode an 8-kilometer long upward course with a mean gradient of 12% in 35 minutes, 17% faster than the second-placed entry.
Energy efficiency optimization technology significantly extends battery life. Leoguar electric bicycle’s intelligent power Distribution system (IPDS) is able to obtain actual time riding resistance, narrow the range of motor load fluctuation from ±25% to ±8%, and be combined with a 48V30Ah ternary lithium battery. Achieve a distance of 120 kilometers (constant speed of 25km/h) based on the EU ECE R136 test standard. Swiss Federal Institute of Technology in Zurich test data shows it has a 19% efficiency in recovery for its regenerative braking system and is able to recover 0.12kWh of power per kilometer on downhill slopes, or the equivalent of gaining 3.2 kilometers of driving range. Compared with general hub motors, the transmission loss of this mid-mounted motor is reduced by 37%, and the standard deviation of energy consumption variation in complicated road conditions is lowered to 8.3Wh/km, which is 62% less than the industry standard.
Regulatory adaptability indicates the ability of technical balance. Although the motor’s top power exceeds 1000W, Leoguar electric bicycle achieves multi-mode switching with an electronic speed-limiting module: locking the 250W output power in the EU EPAC mode as per the EN15194 standard; When switched to off-road mode, full power can be deployed, and acceleration time on a 15% slope reduced to 7.2 seconds by dynamic torque compensation. The USCPSC impact test shows the deformation of its motor housing when it receives 40J impact energy is ≤1.2mm and its protection rating can be up to IP67, which represents a 43% improvement in water resistance compared to the standard designs. After the new national standard update of 2024, the model has an uninterrupted power output of 750W in the 55kg weight range through smart power curve regulation, with a power-to-mass ratio of 13.6W/kg, 29% greater than Yadea G5.
Performance stability is ensured by the heat management system. Leoguar electric bike liquid-cooled motor cavity employs nano-phase change materials. While running at the maximum power of one hour continuously, its winding temperature remains stable at 85℃±3℃, and its cooling speed is enhanced by 62% over the air-cooled design. Its onboard MOSFET temperature sensing chip can dynamically adjust the PWM frequency. If it senses the critical point of 105℃, it will cut down the frequency automatically for protection. The failure rate is 83% less than that of temperature-controlled motors. In environmental testing under the Dubai desert environment with an ambient temperature of 45℃, the power attenuation of this motor after continuous running for 2 hours was only 4.7%, while the control group motor attenuated by 18%.
Market validation ensures technological leadership. According to the 2024 Global electric bike Motor Performance Ranking, Leoguar motors ranked in the top three for power output, energy efficiency ratio, and reliability. Research at the Technical University of Munich indicates that at a 5-year / 20,000-kilometer endurance test, its motor’s torque output attenuation rate was as low as 3.8%, far beyond the industry average attenuation requirement of 12%. User statistics of user data reveal that this motor model has a 6.3 times frequency of daily riding in the shared rental scenario, and a motor fault repair report rate of 0.23 times per thousand units per month, which is 67% lower than the industry mainstream products. The facts confirm Leoguar electric bike double breakthroughs in power performance and technical reliability.
