Catalog of Bafang mid-drive motors
This catalog covers the Bafang mid-drive motors you can buy on their own and fit to an existing bicycle: the BBS series. Three models, one shared architecture, three controller amperages. Every row carries the model's reference price and links to its full review.

How to read this catalog
The price shown is the reference price of the model: the entry-level version, motor only, without a battery. It is also the value repeated in the spec sheet and the comparison table, so that no page on the site can quote a different figure. In the review pages you will read a range instead: these motors pass through many retailers, and the price depends on the axle version, the controller and the display included. What drives that variation is detailed in Bafang motor prices.
Every review shows the same seven specifications, in the same order: rated power, maximum torque, supply voltage, sensor type, controller maximum current, bottom bracket compatibility, and motor weight. This identical grid is what makes two models genuinely comparable — a sheet that picks its own fields always flatters the product it describes.
The three models in one line
| Model | Torque | Controller | Bottom bracket | Best for |
|---|---|---|---|---|
| BBS01B | 80 Nm | 15 A | 68–73 mm | City riding, gentle terrain, legal status preserved at 250 W |
| BBS02B | 120 Nm | 25 A | 68–73 mm | Loaded touring, moderate to sustained relief |
| BBSHD | 160 Nm | 30 A | 68–100 mm | Cargo, mountain, fat bike |
All three share the same cadence sensor and the same fitting principle. The choice therefore comes down to just three variables: what you carry, the terrain you face, and what your frame will accept. Which Bafang motor to choose for your use walks through these questions in order.
What this catalog does not cover
Hub motors, mounted inside the wheel, are not listed here: this site covers mid-drive motors, whose effort passes through the bike's drivetrain rather than through the wheel. Motors supplied directly to bicycle manufacturers and built into the frame at the factory are also absent — they cannot be bought separately, and they cannot be retrofitted.
Two measurements before buying any kit
Measure your bottom bracket width, face to face, and the clear space between the shell and the right chainstay. These two numbers alone eliminate half of all ordering mistakes — the full procedure is in the Bafang kit installation guide.
