Does size matter? It’s a query as old as time that, depending on who you ask and in what situation, is going to yield a broad and potentially colorful range of answers.
In the less colorful context of electric bikes, motor size (to most people) very much does seem to matter. The general consensus is that bigger is better. More watts equals more power; equals more speed; equals an easier time climbing hills. But is bigger always better, or can a carefully tuned smaller motor compete with sheer wattage?
We set out to explore this question with a simple test: A head-to-head uphill race between a powerful 750W rear hub motor e-bike and a 500W rear hub motor e-bike that the brand claimed had been specifically tuned for hill climbing.
The result of that test was about as we expected, with the more powerful bike winning our race, but the relationship between motor size and climbing ability is far more complicated than power alone.
