What are Watt-Hours and Amp-Hours?

One of the first questions riders often have about electric bikes is, “How far can I go on a single charge?” The answer depends on several factors – terrain, rider weight, pedal assistance level, and, crucially, the battery’s capacity. Understanding the battery capacity is key to estimating range, but you’ll often see two different metrics thrown around: watt-hours (Wh) and amp-hours (Ah). So what’s the difference, and which one should you focus on when estimating range? Let’s dive in.
