This is what I actually wanted to say, thank you.Nothing wrong with hub motors; I would bet Rad sells 20 Radwagons for every Big Easy Surly sells. The price point where you get into mid drive cargo bikes is several thousand dollars, which is hard to justify for a lot of people. Hub motors are less expensive and mechanically simpler, and the drawbacks (your powered drivetrain being singlespeed and torque sensing being absent or not as refined) probably don't even matter on a utility bike for many people.
First question will be: Is it the rated mechanical or electrical power? I guess it is electrical as it helps selling actually not that powerful motors as they seem to be.Where 750W motors are allowed a rear hub motor combined with 8spd derailleur is great option for cheap cargo bike. Will need a large >750WH battery to deliver high power draw of these large motors.
Incorrect: the 250 W is only a nominal value. A cargo mid-drive motor can produce about 600 W of mechanical peak power, which translates to 750 W of electrical power. Additionally, that power works on the rear wheel via the gearing.For most of world where 250-300W is max motor size middrive is only way to deliver performance on hilly terrain.
