A/B tests, controlled experiments to measure performance differences between groups, are ubiquitous tools in data science and represent the gold standard in business measurement. At Lyft, A/B tests are found in nearly every product, from measuring the performance of marketplace algorithms and app designs, to engineering infrastructure changes. The units of analysis for most A/B tests are users, and sometimes markets or times of day. In this post, we are going to describe a new type of A/B test we are performing on our hardware team at Lyft. We will also illustrate a couple of A/B tests which we have done to safely and confidently improve the user experience, lower costs, and provide the best possible service for the cities in which we operate.

A/B测试，即测量不同组别之间性能差异的受控实验，是数据科学中无处不在的工具，代表了商业测量的黄金标准。在Lyft，A/B测试几乎出现在每个产品中，从测量市场算法和应用程序设计的性能，到工程基础设施的变化。大多数A/B测试的分析单位是用户，有时是市场或一天中的时间。在这篇文章中，我们将描述一种新型的A/B测试，我们正在Lyft的硬件团队中进行。我们还将说明我们所做的几个A/B测试，以安全和自信地改善用户体验，降低成本，并为我们运营的城市提供尽可能好的服务。

Lyft’s TBS (Transit, Bikes, and Scooters) team is the largest bike sharing network in North America (Citi Bike, Divvy, and Bay Wheels to name a few systems), and runs scooters and transit products integrated into the Lyft app. TBS currently operates four classes of hardware products in many of America’s largest cities — electric and non-electric bikes, electric scooters, and parking stations. Lyft TBS designs, builds, operates, and maintains its own hardware. Our teams of hardware engineers, product managers, data scientists, and others are constantly improving and refining our existing hardware products in addition to designing totally new products.

Lyft的TBS（Transit, Bikes, and Scooters）团队是北美最大的自行车共享网络（Citi Bike,Divvy, andBay Wheels等系统），并运营集成在Lyft应用程序中的滑板车和交通产品。TBS目前在美国许多最大的城市经营四类硬件产品--电动和非电动自行车、电动滑板车和停车站。Lyft TBS设计、建造、运营和维护自己的硬件。我们的硬件工程师、产品经理、数据科学家和其他团队，除了设计全新的产品外，还不断改进和完善我们现有的硬件产品。
