degrees, the depth should surpass the highest safety line, and then lock the
quick release handle on the folding handle.

move inside, at the same time, move the chain from the small part of the rear
flywheel to the large part. These steps will reduce the riding speed while riding,
also will reduce the pedaling strength of riding. When the handle bar at the
maximum position(as shown in picture 3 below), press the accelerator button
on the right derailleur handle, the back derailleur will move outward, at the
same time, move the chain from the large part of the rear flywheel to the small
