Speed selection: select several speeds when the flywheel has several layers. Pay attention to the maximum number of teeth on the original car. The maximum number of teeth should not differ too much, otherwise the upper and lower chains of the bicycle are easy to rub together. For example, the 9S 32T bicycle can use 36T, but it\\'s better not to use 42T flywheel;2. Distinguish between snap flywheel and rotary flywheel: snap flywheel has flywheel cover, rotary flywheel does not.Note:If the chain is used for a long time, it needs to be replaced together with the chain, because the chain will also be worn when the flywheel is worn. Otherwise the service life of the flywheel will be greatly reduced.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
