（一）单车怎么调整
1.FOOT POSITION | 脚怎么放
• If toe cages and straps are used, be sure to align the ball of your foot over the center of the pedal.This is the firmest, widest part of your foot and therefore the most efficient and comfortable foot position.
•如果你用的脚套+束带的话，一定要把你的脚掌最宽处（大脚趾根部）放在踏板轴即脚踏中心。因为这个位置你的脚最结实，最宽，踩踏起最舒服与最高效。
• If clipless pedals are used, make sure that your cleats are aligned properly on yourshoes so that the ball of your foot is positioned on the center of the pedal.
•如果你使用锁鞋，确保锁扣安装在鞋上正确的位置，使得你的脚掌最宽处才在脚踏中心
2.SADDLE HEIGHT | 车座高度
Adjusting your bike’s saddle height is a simple way to improve the comfort and safety of your ride. It’s easy to determine the right height—simply place your feet in the toe cages or clip into the pedals and rotate the pedals until one leg reaches the bottom of the pedal stroke. That leg should have a 25–35 degree bend in the knee.
调整车座高低让你的骑行更加舒适，确定正确的高度实际很简单——脚放在正确的位置（如tip1）,然后踩踏脚踏，直到一条腿触到踏板行程底部（此时你的脚放在6点和12点钟方向），这条腿在膝盖处有25-35度弯曲
3.SADDLE FORE/AFT POSITION | 车座前后位置
The seat also adjusts forward and backward, so that your knees will be properly aligned relative to your feet. Sit on the saddle in riding position, with your hands on the handlebars and the balls of your feet over the center of the pedals. Then position the pedals so they are level with each other. Use your forward leg for the alignment check. Picture an imaginary line (or have someone hold a plumb line) from the front of your kneecap straight down. Your seat is in the right position when your knee cap is directly above the center of the pedal.
车座可以前后适当调整，使膝盖与脚适当对齐。坐在车座上，双手放在车把，脚放在脚踏正确位置（见tips1）,双脚水平放置，也就是3点和9点方向，想象一条线从你的膝盖垂直于地面画出，当线延伸位于脚踏中心也就是你脚掌最宽处时，你的车座前后位置设置正确。
4.HANDLEBAR HEIGHT & FORE/AFT | 车把高度
Adjust the handlebars to a position that is comfortable and limits unnecessary strain on your neck and back. Fore/aft adjustments on the handlebars is available on some models of the Spinner bike.
车把调整到一个舒适的位置，并且你的脖子和背没有不必要的压力，一般设置车座和车把差不多高或车把略微高一点。
NOTICE :以上单车调整适合正常人群，特殊人群（孕妇，伤病患者等）请咨你的SPINNING 教练和医生。
