2.5 Quick Start
Before use, install all components according to the installation guide and check for looseness. Ensure sufficient power. Take protective measures while riding.
Step 1: Adjust Handlebar and Saddle
Adjust the handlebar and saddle to suit the rider's height. Ensure the quick releases for the saddle post and handlebar stem are securely tightened. It is recommended to adjust the handlebar to a comfortable height based on your riding habits. The saddle is best adjusted to the height of your hip bone, but not higher than the safety line. ?

Step 3: Adjust Gears
Select the riding mode according to road conditions and personal needs. The bicycle is equipped with 5 gears. Press the gear buttons "+" or "-" to change gears. ⚙️ Gear 1 is suitable for relatively flat road conditions. The steeper the incline, the higher the gear you should use.
ATTENTION: When the bicycle is in PAS mode, it has no power but can be ridden like a normal bicycle.
Begin riding after setting the 1st gear. Increase or decrease the gear as needed.
Step 4: Riding on the Road
For your safety, we recommend wearing a helmet while riding. ⛑️
Step 5: Braking Instructions
The left brake lever controls the front brake, and the right lever controls the rear brake. Apply the rear brake first, then the front brake to stop the bicycle. ?
WARNING: Do not apply only the front brake, as this can destabilize the bicycle's center of gravity and lead to falls. ⚠️
