If you want to upgrade your bike with an electric motor system, you might have come across two popular options: the TSDZ2 and the BBS02. Both of these are mid-drive systems, which means they replace your bike’s bottom bracket and crankset and drive the chain directly. This has some advantages over hub motors, such as better weight distribution, more efficient use of battery power, and better performance on hills.
But how do these two systems compare with each other? Which one is better suited to your needs and preferences? In this post, I will answer these questions by comparing the TSDZ2 and the BBS02 on four main aspects: performance, installation and maintenance, compatibility, and price. This will help you decide between these two e-bike motor systems.
Compare TSDZ2 and BBS02 by Specs
One of the most important factors to consider when choosing an e-bike motor system is how well it performs on the road. Here are some key aspects of performance that you should pay attention to:
Power output
The power output of a motor system is measured in watts (W) and determines how fast and far you can go with your e-bike. The TSDZ2 comes in three versions: 250W, 350W, and 500W. The BBS02 comes in two versions: 500W and 750W. As you can see, the BBS02 has a higher power output than the TSDZ2, which means it can provide more speed and acceleration. However, this also means that it consumes more battery power and may not be legal in some countries or regions where there are limits on e-bike power output.
Torque
The torque of a motor system is measured in Newton meters (Nm) and determines how much force it can apply to the chain. The higher the torque, the better the motor system can handle steep hills and heavy loads. The TSDZ2 has a torque of 80Nm, while the BBS02 has a torque of 120Nm. This means the BBS02 has a clear advantage over the TSDZ2 when climbing hills and carrying cargo. However, this also means that the BBS02 stresses the chain and drivetrain components, which may cause more wear and tear.
Noise level
The noise level of a motor system is measured in decibels (dB) and determines how loud it is when operating. The lower the noise level, the more discreet and pleasant the motor system is. The TSDZ2 has a noise level of about 50dB, while the BBS02 has a noise level of about 65 dB. This means the TSDZ2 is much quieter than the BBS02, which can be noisy and annoying for some riders and bystanders.
Pedal assist levels
The pedal assist levels of a motor system determine how much assistance it provides when you pedal your e-bike. The more levels there are, the more control you have over your riding experience. The TSDZ2 has four-pedal assist levels: eco, tour, sport, and turbo. The BBS02 has nine pedal assist levels: 0-8. This means that the BBS02 offers more customization than the TSDZ2 when it comes to adjusting the level of assistance according to your preference and terrain.
Throttle mode
The throttle mode of a motor system allows you to control the speed of your e-bike without pedaling at all. This can be useful when you need a boost or want to rest your legs. The TSDZ2 does not have a throttle mode, while the BBS02 does have a throttle mode. This means the BBS02 offers more versatility than the TSDZ2 when riding your e-bike without pedaling.

Installation and Maintenance
One of the factors to consider when choosing an e-bike motor system is how easy it is to install and maintain. The TSDZ2 and the BBS02 are mid-drive motors that replace your bike’s bottom bracket. However, there are some differences in how they are installed and maintained.
The TSDZ2 is generally easier to install than the BBS02, requiring no special tools or skills. You must remove your existing bottom bracket, fit the motor unit into the frame, tighten the lock ring, and connect the wires. The BBS02, on the other hand, requires a special tool to tighten the lock ring, which can be hard to find or expensive to buy. You must also be careful not to damage the wires or the controller when installing the motor.
The maintenance requirements for both motors are similar, as they need regular cleaning and lubrication. However, the TSDZ2 has a more modular design, making replacing or repairing individual components easier. For example, if they fail, you can easily swap out the torque sensor or the controller. The BBS02 has a more integrated design that makes it harder to access or replace some parts. For example, you must open the motor casing to access the controller or the gears.
The availability of spare parts is another factor to consider. The TSDZ2 is a relatively new motor system not widely distributed or supported by many vendors. Finding spare parts or getting technical support can be challenging if you encounter any issues. The BBS02 is a more established and popular motor system with a larger distributor and supplier network. This means finding spare parts or getting technical support if needed is easier.

Compatibility
Another factor to consider when choosing an e-bike motor system is its compatibility with your existing bike and accessories. The TSDZ2 and the BBS02 are compatible with most standard bike frames with a 68mm or 73mm bottom bracket shell. However, there are some differences in how they work with other components.
The TSDZ2 is more compatible with different types of batteries than the BBS02. The TSDZ2 can work with any 36V or 48V battery with a standard XT60 connector. The BBS02 can only work with 48V batteries with a specific connector matching the controller. This means you have more options and flexibility when choosing a battery for the TSDZ2 than the BBS02.
The TSDZ2 is also more compatible with different types of displays than the BBS02. The TSDZ2 can work with any UART protocol display, such as VLCD5, VLCD6, XH18, or SW102. The BBS02 can only work with CAN protocol displays, such as C965, C961, DPC18, or 850C. This means you have more options and flexibility when choosing a display for the TSDZ2 than for the BBS02.
The TSDZ2 is less compatible with different types of controllers than the BBS02. The TSDZ2 has a built-in controller that cannot be replaced or upgraded. The BBS02 has an external controller that can be replaced or upgraded with different models with different features and performances. This means you have more options and flexibility when choosing a controller for the BBS02 than the TSDZ2.
Compare the Price
The price is one of the most important factors to consider when choosing an e-bike motor system. How much does it cost to buy, install and maintain a TSDZ2 or a BBS02? And which one offers more value for money? Let’s compare them.
Comparison of retail prices
The retail prices of both motor systems vary depending on the seller, the model, and the accessories. However, a general range can be given based on some online sources. The TSDZ2 usually costs between $300 and $400, while the BBS02 costs between $400 and $500. This means the TSDZ2 is average cheaper than the BBS02 by about $100.
Cost of installation and maintenance
Both motor systems are relatively easy to install and maintain, as they are designed to fit most standard bike frames and components. However, some differences may affect the cost of installation and maintenance.
The TSDZ2 is a mid-drive motor that replaces the bottom bracket and crankset of the bike. It has a built-in torque sensor measures the pedaling force and adjusts the power output accordingly. This makes it more efficient and natural to ride but also more complex and sensitive to damage. The TSDZ2 requires a special tool to remove and install, which may not be available at every bike shop. It also needs regular firmware updates to ensure optimal performance and compatibility with different displays and batteries.
The BBS02 is also a mid-drive motor that replaces the bottom bracket and crankset of the bike. However, it does not have a torque but a cadence sensor that measures the pedaling speed and provides a constant power output regardless of the pedaling force. This makes it simpler and more reliable but also less efficient and responsive. The BBS02 does not require a special tool to remove and install, as it uses standard bolts and washers. It also does not need firmware updates; it works without issues with most displays and batteries.
Based on these differences, the TSDZ2 has a higher installation and maintenance cost than the BBS02, as it requires more specialized tools and services.
