The new version of the TSDZ2B 36V 250W motor updates the TSDZ2 with two couplings on the large sprocket to ensure smoother, more efficient operation and a longer lifespan. Compatibility & Installation: This motor is designed for bicycles made of aluminum alloy with bottom bracket of 68-73 mm in length and 33.5-36 mm inner diameter, adhering to the JIS standard and suitable only for bicycle models with chain drive and disc or V-brakes. Refined Description : Centralized Safety & Balance – The mid mounted motor design evenly distributes weight for a stable ride. Its compact modular build includes an integrated cadence sensor, sealed with waterproofing for enhanced reliability, skipping intermediate connectors. The motor’s output aligns with pedal movement, instantly ceasing upon pedal release. During crank idling, the motor remains stationary, mirroring a standard bicycle’s safety. Elevated Cycling Adventure : Explore diverse terrains effortlessly with three adaptable riding modes: Throttle, Pedal Assist, and Bike Mode. Our intelligent torque-sensing motor responds intuitively to your pedaling effort, ensuring a seamless personal experience. Introducing the upgraded EKD01 display, featuring Blue/tooth connectivity, built-in navigation, Type-C charging, 4-level adjustable brightness control, and multilingual support – all enhancements over the old VLCD-5 model. Fits 95% of standard bike frames with 68-73mm bottom bracket and 34-36mm inside diameter. 30% lighter than a Bafang motor for almost the same power output. Built in torque and cadence sensor – this results in much smoother acceleration than any cadence sensored mid motor. Kit includes all installation hardware and tools. The motor has an extra support mount – resulting in a much more reliable install than a Bafang BBS motor. 80Nm of torque is almost twice as much as a hub motor and can help you climb up any hill in your way.
