  1. I recommend that you actually measure watts when you test 250 watt rated motors. It was reported in the 2020 Ebike Future Conference that 95% of the 250 watt motors tested exceeded the 250 watt rating.

  2. Not to blur the lines of this article but manufacturers are known to under rate their motors to compete with European regulations or over rate them to compete with higher powered motors available to U.S. customers for example. In fact several even advertise that they are happy to provide you with a sticker stating your desired wattage needed to comply with your countries regulations.

  3. Thanks for explaining the difference in power, torque and wattage, had been looking for this info for a while

    I’m 200lbs and I’ve been satisfied with a 250 Watt ebike for last 5 years, only use the power as a backup when I hit hills. If your riding primarily for exercise a lower wattage isn’t a bad thing. My bike won’t push me up a hill without my effort

  4. Nothing wrong with 250 W motor. I use a 750 w motor with 42x 11/36 for gears. Rode Crater Lake rim road 22 miles in and out at level 1 about 150 w. 750 w with a big battery = more fun. 250 W is cheaper, that’s about it.

  5. It comes down to the controller. It is easy enough to go into the settings to increase the peak wattage. For example, ebikes rated as 750 watts sold in the US and ones sold in Canada rated as 500 watts due to the different legal limits of each country, have the same motor size.

  6. I have an R Martin E-bike that came with a 250 watt and 36 volt battery setup with mid-drive, and this it is just right if you intend to provide plenty of pedaling during your ride. If you intend to ride it more like an electric scooter, it probably would be disappointing. For how I intend to ride, it’s a perfect ratio. It does limit power to around 18-20 mph and then the motor kicks out.

  7. A good quality mid drive 250W motor is definitely ample for most uses – from urban commuting to country cycle touring. It also generally ensures safer riding and interactions on shared paths and bikeways. If riders are tempted to hit higher speeds they do not belong on paths that are there to protect people moving at lower speeds. I support the European and Australian pedelec restriction to 250W. Thanks for your dissection of this issue.
