Dual Assist Modes: Torque & Speed

* First-time torque mode users must complete a one-time horizontal calibration. Both modes can be switched freely at any time.

Torque Mode

Assistance scales with how hard you pedal — push harder, get more power. Ideal for climbing hills and variable terrain.

Speed Mode

Assistance scales with your pedaling cadence — the faster you spin, the more support you get. Perfect for flat roads and commuting.

Automatic Slope Detection

One-Time Horizontal Calibration

Before your first ride in torque mode, complete a quick horizontal calibration:

• Place your fully assembled ebike upright on level ground.
• Open the display or app settings and tap "H Adjust".
• When "OK" appears, calibration is complete — you're ready to ride.

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.)
