warm Tip: When assembling the handlebars, the letters and numbers of the handlebars should be in court, and the left and right sides should not be reversed. Pay attention to the difference between the left and right (L is left, R is right). Turn clockwise on the left and clockwise on the right. Remember that the pedal must be tight! Remember! Remember! Remember! Otherwise, when riding for a period of time, the thread will slide, and even the pedal will fall off (this situation is not within the scope of warranty). First connect the seat and seat tube, then insert them into the frame. Nuts on both sides of the seat need to be locked, don’t just tighten one side, the seat is horizontal, and the front end is slightly lower than the back end, which is the best angle. And after the car is installed, the front and rear disc brake must be on the left side of the car!!! Remember, otherwise it will cause brake disc sliding wire!!! Note: When the car is in use, be sure to dial the transmission while riding. Do not dial the transmission when the car is still, or the transmission will be easily damaged.
