🛑 Brake Cutoff (E-Brake) Sensor Install
Brake cutoff sensors kill motor power the instant you squeeze a lever, the safety net that makes Bafang's cadence PAS feel predictable. Here is how to fit and test them on every build.
🛠️ Classic Pain Points (Read This If You Get Stuck)
The handful of snags that stall most Bafang installs, distilled from ten years of support calls, with the field-tested fix for each so you can get unstuck fast.
🛠️ Front-Hub Kit Install — Step by Step
The front-hub kit is the easiest Bafang install: no bottom-bracket work, you keep your cranks and shifting, and most riders are done in one to two hours. Just don't skip the torque arm.
🔦 Front LED Headlight (Optional Accessory)
The optional Bafang front LED headlight wires off the display's low-voltage output and mounts to your fork crown or handlebar. Here is how to route the lead and mount it cleanly.
⚙️ Gear Shift Sensor Install
The gear shift sensor briefly cuts motor power each time you shift so the chain moves under no load, sparing your drivetrain. Optional on the BBS02 and strongly recommended on the BBSHD.
🛠️ Mid-Drive (BBS02 / BBSHD) Install — Step by Step
The complete walkthrough for installing a Bafang mid-drive, from bottom-bracket removal to the first power-on test. Work through it in order and take your time on the bottom bracket.
🛠️ Mid-Drive on a 73mm Bottom Bracket — the Spacer Setup
Fitting a Bafang mid-drive on a 73mm shell takes two small changes: the longer fixing-plate bolts and a spacer stack. Here is the setup that clamps the motor securely.
