3. Setup
3.1 Head Size Measurement and Helmet Fitting
Proper helmet fit is crucial for safety and comfort. Follow these steps to ensure your helmet fits correctly:
- Use a flexible measuring tape to measure the circumference of your head over your hair.
- Position the tape about 1 inch (2.5 cm) above your eyebrows and above the top of your ears.
- Repeat the measurement a few times to ensure accuracy and use the largest number as your head size.
- Refer to the size chart below to choose the appropriate helmet size.
| Suggest Size | Head Circumference |
|---|---|
| M | 20.4-22.1 inches (52-56 cm) |
| L | 22.4-23.6 inches (57-60 cm) |
Once you have selected the correct size, place the helmet on your head. Use the adjustable dial at the back of the helmet to tighten or loosen the fit until it is snug but comfortable, without causing pressure points. The helmet should not move excessively when you shake your head.

5. Maintenance
5.1 Cleaning the Helmet Shell
To clean the helmet's exterior, use a soft cloth dampened with mild soap and water. Avoid harsh chemicals, abrasive cleaners, or solvents, as these can damage the helmet's finish and materials. Rinse with clean water and air dry.
5.2 Cleaning and Replacing Inner Pads
The helmet includes two sets of interchangeable soft inner pads for easy replacement and washing. To clean the pads:
- Gently detach the inner pads from the helmet.
- Hand wash the pads with mild soap and cool water.
- Rinse thoroughly and allow them to air dry completely before reattaching.
- To reattach, align the hook-and-loop fasteners on the pads with the corresponding areas inside the helmet.

6.1 Rear LED Light Not Functioning
- Check Battery: Ensure the tail light is fully charged. Connect it to the USB charging cable and allow it to charge for 0.5 hours.

6.2 Helmet Feels Uncomfortable or Loose
- Adjust Dial: Use the adjustable dial at the back of the helmet to tighten the fit. It should be snug but not overly tight.
- Strap Adjustment: Ensure the chin straps are properly adjusted and buckled. The straps should form a 'V' shape below your ears.
