Full iOS & Android integration via Bluetooth 5.0. Wirelessly configure smart assist modes, track live speed, calibrate gyroscope sensor angles, and perform over-the-air (OTA) firmware updates.

✅ Included

Modular Upgrades & Expansions

Premium handlebar computer system. Depending on your selected kit edition, it features a crystal-clear display (including high-contrast LCD, vibrant TFT color, or minimalist OLED screens).

Important Notes

Disc Brake Rotor Compatibility

For: S100, S110, P100, P110 front hub motors & S100, P100 rear hub motors

Use a standard 6-bolt disc brake rotor.
Minimum diameter: 160mm — center hole diameter: 44mm.

For: S110, P110 rear hub motors & thru-axle rear hub motors

Use the Keyde customized disc brake rotor (160mm diameter).

Using a Third-Party Battery

Battery voltage must match the motor voltage.

Minimum output current: ≥ 20A (P110 motor requires ≥ 30A).

Observe correct polarity as shown in the diagram.

Disc Brake Installation

Always use the disc brake screws included with the motor to secure the rotor. Using other screws may damage the motor.

(Skip this step if your motor uses V-brake.)
