1. Bafang BBSHD 1000W Mid Drive Motor Kit: Top Pick
The Bafang BBSHD is the most popular mid drive kit for demanding riders. In our research, it consistently receives high marks for its robust power delivery and durability. The 1000W continuous rating and 160 Nm torque make it ideal for steep hills and heavy loads. Owner feedback highlights its reliability over thousands of miles, though some note the added weight affects handling on lighter bikes.
However, the BBSHD may not suit casual riders or those on a tight budget. Its higher power can be overkill for flat terrain commuting. We recommend skipping this if you prioritize lightweight builds or have a bike with a non-standard bottom bracket that requires additional adapters.
- Robust 1000W continuous power with peak 1500W for steep climbs.
- High torque output (160 Nm) for off-road and cargo applications.
- Integrated controller with programmable settings via USB cable.
Pros: Excellent hill climbing ability.; Durable build with metal gears.; Wide compatibility with bottom brackets.
Cons: Heavier than other models at about 10 lbs.
2. Bafang BBS02 750W Mid Drive Motor Kit: Best Value
The BBS02 is a well-rounded mid drive motor that offers excellent value. We compared its specs to the BBSHD and found it delivers sufficient power for most riders, including moderate hills and commuting. Owner feedback praises its reliability and ease of installation. The 120 Nm torque is ample for city riding and light trail use.
That said, if you plan to tackle steep, technical climbs or carry heavy cargo, the BBSHD is a better choice. Some users report that the BBS02 can overheat under sustained high load. We suggest skipping this if you need maximum torque or intend to use it on a heavy tandem bike.
- 750W continuous power with 120 Nm torque for most riding conditions.
- Lighter than BBSHD at 8.4 lbs, easier to handle.
- Programmable controller for tuning power delivery.
Pros: Good balance of power and weight.; Affordable compared to BBSHD.; Smooth pedal assist response.
Cons: Less torque for extreme off-road use.
3. Bafang M600 500W Mid Drive Motor: Best for Torque Sensing
The M600 is Bafang’s torque-sensing mid drive motor, designed for a more intuitive riding experience. Our evaluation shows it excels in providing smooth, proportional assistance based on pedal effort. Owner feedback often highlights how natural it feels compared to cadence-sensing motors. It is a favorite among mountain bikers who want a lightweight setup.
However, the 500W nominal power means it is less suited for high-speed commuting or steep, long climbs. Some riders find the torque sensor calibration finicky. We recommend skipping this if you need raw power for heavy loads or if your bike has a non-standard bottom bracket that may require additional parts.
- Integrated torque sensor for natural pedal assist feel.
- Compact and lightweight design (7.5 lbs).
- Suitable for mountain bikes with standard bottom brackets.
Pros: Natural riding feel with torque sensing.; Lightweight and compact.; Quiet operation.
Cons: Lower power output limits top speed and hill climbing.
4. Bafang M400 250W Mid Drive Motor: Best for Legal Compliance
The M400 is a legal-compliant mid drive motor for those in regions with strict power limits. We researched its performance and found it adequate for flat terrain and gentle slopes. Owner feedback indicates it is reliable and straightforward to install, making it a good choice for first-time converters.
On the downside, the 250W power and 80 Nm torque are insufficient for steep hills or off-road use. Riders over 200 lbs may find the assist lacking. We suggest skipping this if you need significant climbing ability or plan to use it on a heavy bike.
- 250W nominal power compliant with EU/UK regulations.
- Cadence sensor for simple on/off assistance.
- Affordable entry-level option.
Pros: Street legal in many regions.; Easy to install and maintain.; Cost effective.
Cons: Limited power for hills and heavy riders.
5. Bafang BBS01 350W Mid Drive Motor Kit: Best for Commuting
The BBS01 is a solid choice for commuters who need a reliable, efficient motor. Our research shows it offers a good balance of power and range. Owner feedback frequently mentions its ease of installation and smooth operation. The programmable controller allows fine-tuning of assist levels.
However, its 350W power and 80 Nm torque limit its hill-climbing ability. If your commute includes steep grades, consider the BBS02 or BBSHD. We recommend skipping this if you frequently tackle hills or weigh over 250 lbs.
- 350W power suitable for daily commuting.
- Compatible with 36V and 48V batteries.
- Programmable controller for custom settings.
Pros: Reliable and efficient for commuting.; Quieter than some higher power motors.; Good battery range due to lower power draw.
Cons: Not powerful enough for steep hills.
6. Bafang M500 500W Mid Drive Motor: Compact Power
The M500 is a newer torque-sensing motor that offers a good balance of power and size. We compared its specs to the M600 and found it slightly more powerful but with similar natural feel. Owner feedback appreciates its compact design that fits most frames easily.
However, its 95 Nm torque is less than the BBSHD’s 160 Nm, so it may struggle on very steep climbs. Some users report compatibility issues with certain bottom brackets. We suggest skipping this if you need maximum torque for heavy cargo or extreme off-road conditions.
- Torque sensor for natural assist.
- Compact size fits many frames.
- Good power for trail riding.
Pros: Smooth torque sensing.; Compact and lightweight.; Good mid-range power.
Cons: Less torque than BBSHD.
7. Bafang M510 500W Mid Drive Motor: Latest Tech
The M510 is Bafang’s newest mid drive motor, featuring a refined design and integrated cables. Our research indicates it offers similar performance to the M500 but with better aesthetics. Early owner feedback is positive, noting smooth assist and quiet operation.
However, because it is relatively new, long-term durability data is scarce. Some users have reported issues with the CAN bus interface and compatibility with older battery systems. We recommend skipping this if you prefer a proven, widely supported motor like the BBSHD or BBS02.
- Latest generation torque sensor motor.
- Sleek design with integrated cables.
- Compatible with Bafang's CAN bus system.
Pros: Modern aesthetics and cable management.; Smooth torque sensing.; Good power for trail riding.
Cons: Limited owner feedback due to newness.; Potential reliability concerns.
