Supported Models: For 1S, Pro, Pro 2. Installation on M365 scooters requires replacement of the Bluetooth board with our version and upgrading the motor to a higher specification. Attention A. Verify your scooter model is 1S/Pro/Pro 2 and confirm it is an original unit. Compatible models must be genuine; cloned units may not support installation. To use this governor on non-compatible models, replace the Bluetooth board and controller. B. This product modifies the scooter's software settings to adjust speed limits. If the original motor is 250W, maximum speed may be limited due to motor constraints. The motor may not support speeds up to 38km/h. For higher performance, upgrade to a 350W or higher motor. C.
