2. Attaching the Handlebar
- Insert the handlebar stem into the front fork tube.
- Align the handlebar with the front wheel.
- Tighten the stem bolts securely using the provided Allen key. Ensure the handlebar is firm and does not rotate independently of the front wheel.
3. Installing the Front Wheel
- Carefully place the front wheel into the front fork dropouts.
- Ensure the brake pads are clear of the wheel rim.
- Secure the wheel using the quick-release lever or axle nuts. If using a quick-release, ensure it is fully closed and tight.
- Check that the wheel spins freely and is centered.

4. Adjusting Brakes
The scooter is equipped with high-quality V-brakes. Ensure they are properly adjusted for optimal stopping power.
- Squeeze the brake levers to check for proper engagement. The brake pads should contact the rim evenly.
- Adjust cable tension if the brakes feel too loose or too tight.
- Ensure brake levers are easily accessible and provide firm, responsive braking.
5. Kickstand Installation (if applicable)
If your kickstand is not pre-installed, attach it to the designated mounting point near the rear wheel using the provided bolts. Ensure it is secure and allows the scooter to stand stably.

Operating Instructions
1. Riding Position
- Place one foot firmly on the anti-slip footboard.
- Use your other foot to push off the ground, propelling the scooter forward.
- Maintain a balanced posture, keeping your body weight centered over the footboard.
- Periodically switch the pushing foot to reduce fatigue and improve balance.
2. Braking
- To slow down or stop, gently and evenly squeeze both brake levers.
- Avoid sudden, hard braking, especially with the front brake, as this can lead to loss of control.
- Practice braking in a safe, open area to get accustomed to the scooter's stopping distance.
3. Adjusting Footboard Height (Two-level rear fork)
The YEDOO Mula Y40 features a two-level rear fork, allowing you to adjust the footboard height for different terrains.
- Lower Position: Ideal for road use, providing a lower center of gravity and easier pushing.
- Higher Position: Suitable for rougher terrain, increasing ground clearance to prevent scraping.
- Consult the scooter's frame near the rear wheel for instructions on how to adjust the fork position. This typically involves repositioning the rear wheel axle in different slots.
Maintenance
Regular maintenance ensures the longevity and safe operation of your YEDOO Mula Y40 scooter.
1. Tire Pressure
- Check tire pressure before each ride. The recommended pressure is usually indicated on the tire sidewall.
- Proper tire pressure improves ride comfort, efficiency, and reduces the risk of punctures.
2. Brakes
- Inspect brake pads for wear regularly. Replace them if they are worn down.
- Ensure brake cables are not frayed and move freely. Lubricate if necessary.
- Keep brake surfaces (rims) clean and free of grease or dirt for effective braking.
3. Cleaning and Storage
- Clean the scooter with a damp cloth and mild soap. Avoid using high-pressure washers directly on bearings.
- Dry the scooter thoroughly after cleaning to prevent rust.
- Store the scooter in a dry, cool place, away from direct sunlight and extreme temperatures.
4. Fasteners
- Periodically check all bolts, nuts, and quick-release mechanisms for tightness.
- Loose fasteners can lead to instability and potential accidents.
Troubleshooting
