The TSDZ2B is an updated version of the TSDZ2. This new model includes an innovative design that uses two clutches on the main gear. During regular biking, the primary gear disengages from the chain, making it feel almost as natural and easy to ride as a manual bicycle. Aside from this, the new version improves waterproof performance and increases the engine’s lifespan by incorporating integrated parts.

Power and RPM Specifications
Engine Performance
The motor operates at an impressive 4500rpm, paired with 750W of power. This isn’t just jargon; these specifications translate to a thrilling and smooth riding experience. Whether you’re tackling steep inclines or accelerating on flat terrain, this motor delivers reliable, consistent power.
Compatibility Details
Importantly, this kit fits most standard bikes with a 68-73mm bottom bracket. If you need it to fit a 100mm or 120mm bottom bracket frame, make sure to shoot a message before ordering. Compatibility is key to ensuring that installation is smooth and the bike functions properly after the conversion.
Ride Quality: Torque Sensor and Control System
Sensitivity and Stability
The torque sensor technology used in this kit is nothing short of remarkable. It uses resister strain technology for checking torque signals, coupled with digital wireless data transfer. What this means for you is high sensitivity and incredibly stable output. The torque sensor ensures that the motor’s force always changes linearly with human power, making for a smooth, seamless ride.
Real-Time Reactions
One of the standout aspects is how the torque sensor’s detection accuracy pairs with the control system’s reaction speed. The torque output waveform almost perfectly matches the torque waveform produced by your human power. It feels natural and intuitive, almost like the motor is an extension of your own legs.
Independent Controller: Design and Utility
Modular and Compact
The controller is a compact modular design which makes it incredibly convenient. You won’t have to deal with a bulky control unit cluttering your bike. The synthetic step frequency sensor, outward shell, and waterproofing glue add to the controller’s robustness.
No Intermediate Connectors
Another thing I love about this controller is its high reliability due to the lack of intermediate connectors. Fewer connectors translate to fewer points of failure, ensuring your system remains reliable over the long haul.
Safety First: Intelligent Power Cutoff
Synchronized Power Output
One of my main concerns when converting a bike into an e-bike is safety. Rest assured, the Tongsheng TSDZ2B addresses this well. The power output is synchronized with the pedal action. As soon as you release the pedal, the power cuts off immediately. This feature eliminates the need for brake levers and makes the system as safe to use as a manual bicycle.
Idle Crank Protection
When the crank is idle, the motor doesn’t rotate. This feature ensures you’re not surprised by unexpected bursts of power, adding another layer of safety.
Installation and Setup
DIY Friendly
Despite its complexity, the Tongsheng TSDZ2B is relatively DIY-friendly. With clear instructions and online resources, even those who aren’t mechanically inclined can manage to get it set up correctly. The kit includes all necessary components, making the conversion process less daunting.
Essential Tools
While the kit is comprehensive, having a few standard tools on hand will be helpful. These include a bottom bracket tool, pedal wrench, and a hex key set. Having these basics will make the installation process smoother and quicker.
Connection Points
One area to check carefully during setup is the various connection points between components. Ensuring these connections are tight and secure is crucial for both performance and safety.
Real-World Performance
City Commuting
In urban environments, this kit shines. The motor’s power is ample for navigating city streets, and the torque sensor ensures smooth transitions from stoplights. Plus, its compact design means you won’t feel burdened by extra weight.
Mountain Biking
For mountain biking, the 750W motor and excellent torque response provide the added boost needed for inclines and rugged terrain. The waterproof design is particularly valuable for off-road adventures where mud and water are common.
Tricycles
If you’re thinking about converting a tricycle, the TSDZ2B proves equally effective. Stable and smooth, this kit ensures you have the power and control required for heavier loads and different terrains.
Durability and Longevity
Enhanced Waterproofing
Thanks to the improved waterproof performance, this kit holds up well in various weather conditions. You won’t have to worry about rain or puddles damaging your motor or controller.
Engine Lifespan
The updated, integrated parts result in a longer engine life, reducing the need for frequent replacements or repairs.
