Aside from speed, power is probably the hottest topic — and selling point — in the electric bike world.
Conventional wisdom would say that when it comes to power, more wattage is better. But if that’s the case, why do so many high-end e-bikes come with what seem like smaller motors — and is 250W enough power for an electric bike?
There’s a few factors that dictate how much wattage an e-bike needs, ranging from the type of motor being used to how the e-bike was designed. It’s also helpful to understand what manufacturers are describing when they talk about motor wattage, and how U.S. law dictates how powerful an e-bike can be. This post will dive into those details and more.
But here’s a short answer that I’m sure will ruffle some feathers: Yes, we’ve found that 250W is often plenty powerful for many e-bikes. There’s some caveats to that statement, but by and large a 250W motor is enough to give a rider’s pedaling a nice assist. Remember, an e-bike is still a bicycle — by definition at least a little physical effort is required.
