Comparing Specifications: BBS02 vs. M600
Here is a table that summarizes the main specifications of the BBS02 and the M600 motors:
| Specification | BBS02 | M600 |
| Rated Power | 750W | 500W |
| Max Torque | 160Nm | 120Nm |
| Weight | 4.2kg | 3.9kg |
| Voltage | 36V/48V | 48V |
| Max Speed | 25km/h (EU), 32km/h (US) | 25km/h (EU), 45km/h (US) |
| Communication | UART | CAN bus |
| Sensor | Cadence/Speed/Torque (optional) | Triple Sensor (Torque/Speed/Rotor Position) |
You can see, BBS02 has a higher power and torque output than the M600, but also weighs more and has a lower speed limit.
The M600 has more advanced communication system and sensor system than the BBS02, however also requires a special frame mount and has a higher price tag.
Riding Experience: BBS02 vs. M600
The riding experience of the BBS02 and the M600 motors depends largely on the type of bike, battery, controller, display, firmware, settings, and terrain that you use them on.
Normally, you can expect the following differences:
Power and Performance
The BBS02 offers more power and speed than the M600, but also consumes more battery and generates more noise and heat. It is ideal for those who want to cruise on flat roads or tackle moderate hills with ease.
Torque and Agility
The M600 offers more torque and responsiveness than the BBS02. It also requires more pedaling effort and skill.
The M600 is ideal for those who want to challenge themselves on steep climbs or technical trails with agility.
Sensor System and Design
Both motors have a smooth and natural pedaling feel, but the M600 has a more refined and accurate sensor system that adapts better to your riding style and conditions. The M600 more integrated and sleek design that blends well with the bike frame, where the BBS02 has a more bulky and noticeable appearance that may attract attention.

Battery Compatibility and Range
The battery compatibility and range of the BBS02 and the M600 motors depend on the voltage, capacity, quality, and configuration of the battery that you use.
You can expect the following differences:
Battery Compatibility
The BBS02 is compatible with both 36V and 48V batteries, while the M600 is only compatible with 48V batteries.
The BBS02 has more options and flexibility when choosing a battery, but also more complexity and risk when wiring and connecting it.
Power Consumption
The BBS02 consumes more power than the M600, which means that it drains the battery faster and reduces the range. This also depends on the level of assist, speed, terrain, and other factors that affect the power consumption.
The BBS02 can achieve a range of 40-80km on average, depending on the battery size and usage.
Power Efficiency
The M600 consumes less power than the BBS02; it preserves the battery longer and extends the range. It can achieve a range of 60-100km on average, depending on the battery size and usage.
Installation and Maintenance
Different level of skills is required for installing and maintaining the BBSO2 and the M600 motors.The following differences are expected:
Installation Complexity: BBS02 vs. M600
The BBS02 is easier to install than the M600, as it only requires removing the original bottom bracket and replacing it with the motor unit. It is compatible with most standard bike frames and can be installed with minimal tools and skills. The installation process takes about 1-2 hours on average.
The M600 is harder to install than the BBS02. It requires a special frame mount that may not fit all bikes. It is designed for eMTB frames and may require cutting, welding, or modifying the frame to fit. The installation process takes about 3-4 hours on average.
Maintenance: BBS02 vs. M600
