Installation Steps:
- Prepare Handlebar: Remove any existing grip or throttle from the left side of your e-bike handlebar. Clean the handlebar surface.
- Install Throttle Grip: Slide the half twist throttle unit onto the left handlebar. Position it comfortably for your hand.
- Install Right Grip: Slide the remaining grip sleeve onto the right handlebar.
- Secure Components: If your throttle or grips include clamps or screws, tighten them securely to prevent rotation during use. Do not overtighten.
- Connect Wiring: Locate the throttle input on your e-bike controller. Carefully align the 3-pin SM plug from the throttle with the corresponding port on the controller and push firmly until it clicks into place. Ensure the connection is secure.

Post-Installation Check:
After installation, reconnect the e-bike battery. Turn on the e-bike and test the throttle's function in a safe, open area. Ensure smooth acceleration and deceleration, and that the throttle returns to zero when released.
Operating Instructions
The half twist throttle provides variable speed control for your electric bicycle.
- Activation: Once your e-bike is powered on, gently twist the throttle grip towards you to engage the motor.
- Speed Control: The further you twist the grip, the more power is delivered to the motor, resulting in increased speed.
- Deceleration/Stopping: Release the throttle grip to return it to its neutral position, which will reduce power to the motor. Apply brakes as needed to stop.
- Smooth Operation: For optimal performance and to avoid sudden jerks or motor skipping, apply and release the throttle smoothly and gradually.
Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your throttle.
- Cleaning: Wipe the throttle and grips with a damp cloth to remove dirt and grime. Avoid using harsh chemicals or abrasive cleaners.
- Connection Check: Periodically inspect the SM plug connection to ensure it remains secure and free from corrosion.
- Cable Inspection: Check the throttle cable for any signs of wear, fraying, or damage. Replace if necessary.
- Smooth Movement: Ensure the twist mechanism moves freely without sticking. If it feels stiff, a small amount of silicone-based lubricant can be applied to the rotating parts, avoiding electrical contacts.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Throttle not responding | Loose or disconnected SM plug; E-bike power off; Faulty throttle or controller. | Check SM plug connection; Ensure e-bike is powered on; Test with a known good throttle (if available) or consult a technician. |
| Unstable or jerky speed control | Twisting throttle too quickly; Loose connection; Internal throttle issue. | Apply throttle more smoothly and gradually; Check SM plug connection; If problem persists, consider throttle replacement. |
| Throttle stuck or stiff | Dirt or debris; Mechanical obstruction. | Clean around the twist mechanism; Apply a small amount of silicone lubricant; Ensure no cables are interfering with movement. |
