Designed for enjoyment and comfort, the Young Electric Hybrid/Crossover Torque Sensor E-Bike is perfect for a joyful casual ride. The powerful integrated driving system-the combination of motor, top-tier torque sensor and controller-automatically recognizes your pedaling power and tells the motor how hard it should work. This powerful E-bike helps you tackle hills and inclines with ease then takes a break on flatter terrain to conserve the battery life and thus to extend your journey. If you want to enjoy smoother, longer and relaxing rides, this is the bike for you!
