This video presents a comprehensive review and installation guide for the TONGSHENG TSDZ16 1000W mid-drive motor conversion kit, a rising Chinese electric bike motor brand that aims to compete with established European manufacturers. The video demonstrates the complete installation process on a 1×9 gear, 27.5-inch wheel bicycle, detailing each step from removing pedals and the crankset to mounting the motor, installing the speed sensor, and securing all cables and components. The kit includes the motor unit, crankset studs, display screen, speed sensor, hand throttle, hub wrench, and necessary hardware. The reviewer emphasizes proper speed sensor alignment and magnet distance calibration for optimal performance. The standout feature is the torque sensor’s exceptional responsiveness—the motor engages almost instantaneously upon initial pedal movement, even before completing a quarter turn, providing immediate power delivery. The hand throttle includes a slight delay mechanism as a safety feature to prevent accidents given the motor’s substantial power output. Off-road performance testing reveals impressive hill-climbing capabilities, with the 44T crankset and 42T rear sprocket configuration enabling the bike to overcome steep inclines of 50-70% with ease. On asphalt surfaces, the motor accelerates rapidly up to 50 km/h and features a 60 km/h speed limiter that can be adjusted through display settings, though the reviewers recommend keeping this safety feature enabled. Urban hill performance is excellent, easily handling 40-45% inclines in third or fourth gear without requiring first gear. The reviewers conclude that the TONGSHENG TSDZ16 1000W offers versatile performance suitable for both off-road and asphalt riding, whether for cardiovascular exercise or adrenaline-seeking adventures, delivering impressive power and responsiveness that exceeded their expectations.
