Upgraded 48V 500W TSDZ2B Mid Drive Ebike Conversion Kit for 68-73MM Bottom Bracket Bikes

🚵 [Upgraded TSDZ2B Mid Motor] The upgraded TSDZ2B motor boasts a one-piece reduction gear kit, replacing the one-way bearing and enabling it to withstand higher torques. It now utilizes a bidirectional free-wheeling clutch, replacing the traditional one-way version. This reduces motor resistance and ensures effortless pedaling even when the motor is turned off. Complemented by an enhanced motor control program, the TSDZ2B is compatible with a wider range of digital displays, catering to diverse user preferences and requirements.

🚵 [Ease of Installation & Compatibility] The TSDZ2B 48V 500W mid-drive kit comes equipped with a full accessory kit, designed for simple installation. It fits a broad range of bottom bracket sizes, from 68-73mm, allowing you to transform your city bikes, mountain bikes, trikes, or cargo bikes effortlessly. The kit includes a default brake lever, but if your brakes are hydraulic or integrated with the shift, please let us know, and we will send you the replaced brake sensor.

🚵 [Great Power & Torque Sensor Motor] Harness the raw power of our TSDZ2B mid-motor, delivering an impressive 100N.m of torque for effortless acceleration and hill-climbing prowess. Reach a maximum speed of 45KM/H on flat ground. The motor boasts a high-precision torque sensor and a dual-closed dynamic energy controller. In conjunction with the Pedal Boost, it can achieve a virtually instantaneous response. This not only accurately collects your stepping power but also provides a smooth power output, making your riding experience more comfortable and safe.

🚵 [Lightweight & Safe Design] Weighing just 3.6KG, this motor adds minimal weight to your bike, ensuring agility without compromising on performance. Strategically placed at the center of the bike, the motor's position helps to distribute the e-bike's weight more uniformly. It is 30% lighter than a BBS02B motor, while offering similar power output. The motor's output aligns seamlessly with your pedal movement, instantly ceasing upon pedal release. During crank idling, the motor remains stationary, mirroring the safety of a standard bicycle.

🚵 [Optimized Riding Experience] This torque-sensing motor offers three adaptable riding modes (Throttle mode, Pedal Assist mode, and Bike mode) tailored to various terrains, intuitively adjusting to your pedaling force and delivering a seamless and personalized cycling adventure. We also provide the new colorful display EKD01, which offers more features than the old VLCD-5, such as Bluetooth connectivity, navigation, Type-C charging, 4-level brightness adjustments, and support for multiple languages.
