Install Your Bafang BBS01B 250/350W e-bike kit in 6 Simple Steps

Preparation

Before diving into the installation, ensure you have the following:

• Bafang BBS01B 250W or 350W mid-drive motor kit (including battery, display, and all necessary components)
• Compatible bike frame (check for standard 68-73mm bottom bracket width)
• Essential tools:
  • Wrenches (various sizes)
  • Allen keys (hex wrenches)
  • Crank puller
  • Bottom bracket tool
  • Optional: Bafang-specific tool kit
• Clean, well-lit workspace

Step 1: Disassemble Existing Components

1. Pedals: Use a pedal wrench to remove both pedals from the crank arms.
2. Crank Arms: Carefully remove the crank arms using a crank puller. Refer to the tool’s instructions or online tutorials if needed.
3. Bottom Bracket: Utilize a bottom bracket tool to remove the existing bottom bracket from the bike frame.

Step 2: Install the Bafang BBS01B Motor

1. Insert the Motor: Gently slide the BBS01B motor into the vacant bottom bracket shell. Ensure proper alignment and a snug fit. Utilize spacers if necessary to bridge any gaps between the motor and frame.
2. Secure the Motor: Employ the provided fixing plate, lock washer, and bolts to firmly secure the motor to the frame. Tighten the bolts to the specified torque using a torque wrench to prevent damage.

Step 3: Connect Battery and Wiring

1. Mount the Battery: Securely attach the battery to the bike frame, typically on the downtube or in a dedicated bag, using the included brackets. Prioritize weight distribution and battery protection when choosing a location.
2. Connect the Wiring: Route the motor cable along the downtube, securing it with zip ties. Carefully connect the wiring harnesses from the motor to the battery, display, brake levers (if applicable for e-brake cut-offs), and throttle (if included). The BBS01B’s color-coded connectors simplify this process. Double-check each connection against the provided wiring diagram.

Step 4: Install Display and Controls

1. Mount the Display: Securely attach the display to your handlebars in a position that is easily visible while riding.
2. Connect Cables: Route the display cable along the handlebar and connect it to the corresponding port on the motor wiring harness. Ensure all cables are neatly organized and secured with zip ties to prevent any interference or damage.

Step 5: Reinstall Crank Arms and Pedals

1. Install Crank Arms: Slide the crank arms back onto the BBS01B’s spindle, ensuring they are correctly aligned. Tighten them securely using a crank arm tool or wrench.
2. Reattach Pedals: Screw the pedals back onto the crank arms, tightening them to the manufacturer’s recommended torque.

Step 6: Test and Fine-Tune

1. Adjust Shifting: After installing the BBS01B, your derailleur might require minor adjustments to ensure smooth and precise gear changes.
2. Configure Display Settings: Refer to the display manual to personalize settings such as power levels and other features to suit your preferences.
3. Test Ride and Troubleshooting: Take your newly electrified bike for a short, controlled test ride. Verify that everything functions as expected and address any issues like unusual noises, shifting problems, or motor cut-outs. Consult the troubleshooting guide in the manual or seek online resources for assistance.
