自行车功率计

自行车功率计(cycling power meter)是自行车上量测驾驶者输出功率的装置。 大部份的功率计会用应变片来量测力矩,若有角速度的资讯,也可以量测功率[1]。
此技术是在1980年代后期应用在自行车上,也在职业自行车比赛中测试过,当时测试的队伍是Power Pacer原型(Team Strawberry),选手是格雷格·莱蒙德,使用的设备是SRM。此设备已在1989年起商品化,越来越多人使用功率计进行自行车训练。
功率计也可以用无线通讯的方式,传输资料到自行车电脑、智能手机和智能手表。自行车功率计可以即时回馈给自行车运动员,可以精准分析骑车过程,也是训练时很好用的工具。
