New Upgraded Motor (S110 & P110)
1. Enhanced Heat Dissipation — Keyde’s customized disc brake rotor design allows the rotor and motor housing to work together for more effective cooling.
2. Improved Waterproofing — Redesigned sealing for stronger protection against rain and splashes.
3. Greater Stability — The flywheel assembly has been upgraded from a 3-claw to a 6-claw structure, with click count increased from 36 to 78 — delivering significantly improved reliability and smoothness.
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
|
 |
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.) |
