BAFANG 3.5in DPC18 eBike Display for BBS01B, BBS02B and BBSHD, UART Protocol, 0–9 Assist, Auto Backlight

BAFANG 3.5in DPC18 is a dedicated e-bike computer that displays ride data, manages 0–9 pedal assist levels, and connects directly to BBS01B, BBS02B and BBSHD mid-drive motors.

This compact 3.5-inch display replaces or upgrades the original Bafang interface to give clear ride metrics, automatic screen brightness, and a USB charging port while communicating using the UART protocol. It’s designed specifically for the Bafang BBS series mid-drive motors; compatibility with other motor systems is not guaranteed. The screen is IPX5-rated for protection against rain and splashes and provides an intuitive control surface for changing assist levels and viewing speed, distance and battery information.

How does the DPC18 improve visibility and usability while riding?

The 3.5-inch HD LCD gives a larger, clearer readout than many stock displays so you can check speed, assist level and trip data at a glance. An automatic backlight adjusts to ambient light, reducing glare in bright sun and improving readability at dusk. Controls are positioned for quick thumb operation so adjustments are safe and easy on the move.

• 3.5" HD screen for easy data reading from the handlebar
• Auto-dimming backlight adapts to changing light conditions
• Thumb-friendly controls for safe in-ride adjustments
• Displays speed, odometer, trip distance, assist level and battery status

Will this display work with my Bafang mid-drive motor?

The display is built to interface with BAFANG BBS01B, BBS02B and BBSHD mid-drive motors via UART protocol. It is not universally compatible with all e-bike motors or third-party controllers, so verify your motor model before ordering. Refer to photos and wiring diagrams to confirm connector and pin layout match your bike.

• Compatible: BBS01B, BBS02B, BBSHD mid motors
• Communication: UART protocol for reliable control and telemetry
• Not compatible: many hub motors and non-Bafang controllers
• Check product wiring image to confirm connector match

What extra features does the display include for longer rides?

In addition to ride data, the DPC18 includes a USB output so you can charge a phone or device on the go. The unit’s IPX5 rating protects it from splashes and light rain, letting you ride through changing weather without immediate worry. The range of 0–9 pedal assist levels provides fine control over how much motor support you use.

• USB charging port to power devices while riding
• IPX5 splash resistance for wet-weather protection
• 0–9 pedal assist levels for granular power control
• Shows battery level to manage energy during long trips

How easy is installation and daily operation?

Installation is straightforward for bikes already using Bafang BBS series systems: the connector and protocol are the same, so it commonly plugs into the existing harness. Basic operation uses a few buttons to cycle modes and adjust assist levels, letting you focus on the ride. For first-time installers, double-check wiring diagrams and consider a qualified installer if you’re unsure about electrical connections.

• Plugs into existing BBS wiring harness on compatible bikes
• Simple button layout for quick mode and assist changes
• Refer to included images for connector and mounting orientation
• Professional installation recommended if you’re not comfortable with e-bike wiring

Who is this display for? The BAFANG 3.5in DPC18 is for riders using Bafang BBS01B, BBS02B or BBSHD mid-drive motors who want a clearer, smarter handlebar display. It suits commuters and recreational riders who value readable data, adjustable assist granularity and on-the-road device charging. If you have a compatible BBS motor and want an upgrade that balances visibility, weather resistance and convenience, this display is a practical choice.
