QNUT EC150 Brake

Yes. At QNUT, rider safety is engineered into every detail. From power management to system diagnostics, QNUT e-bikes are built with smart protections to ensure a secure and intuitive riding experience for all riders, including beginners.

All QNUT e-bikes include a Level 0 pedal-only mode, which fully disables motor assistance.

• No motor assistance is activated
• The bike operates like a traditional bicycle
• Motor assistance only engages when the rider intentionally increases the pedal assist level

This ensures riders always maintain full control from the first pedal stroke.

QNUT e-bikes are equipped with an integrated brake sensor cutoff system.

When the brake lever is applied:

• Motor power is immediately disengaged
• Pedal assistance stops instantly
• Braking becomes smoother and more responsive

This helps improve safety during sudden stops or emergency braking situations.

Yes. QNUT e-bikes feature smart thermal protection to help protect the motor and drivetrain.

The system continuously monitors internal temperatures. If temperatures exceed safe operating levels, the motor power will automatically reduce or disengage to help prevent overheating and long-term component damage.

Yes. QNUT e-bikes include throttle protection designed to prevent excessive stress on the drive system.

If the throttle is continuously activated for an extended period, the system may temporarily limit output to reduce strain on the motor and drivetrain, helping maintain long-term performance and reliability.

QNUT e-bikes use an advanced Battery Management System (BMS) with over-current protection.

The BMS provides:

• Continuous battery health monitoring
• Over-current protection
• Automatic sleep mode during extended periods of inactivity

These protections help improve battery safety, extend battery lifespan, and maintain long-term reliability.

Yes. QNUT e-bikes feature real-time smart diagnostics.

The controller continuously performs system checks and displays error codes when issues are detected.

This helps riders quickly identify and troubleshoot operational problems with clear and actionable information.
