When they are about to stop, the wheels should swing briskly back and forth and should not stop rotating suddenly. The handlebar should be able to rotate left and right flexibly, and the pedal shaft and crank should be tight, not loose from each other, and rotate flexibly.

3. The transmission vehicle should have correct gears within the transmission range, the transmission position should be clear, and there should be no gaps in the middle.

4. The chain should be appropriately tight and flexible in operation. Shake the crank sprocket repeatedly in forward and reverse directions by hand. The chain will run flexibly and there should be no chain skipping or falling off.
