When is a hub motor not a hub motor? When it's used to drive a chain ring of course...
Here's one I made earlier:
and there are a few others (much neater) near the bottom of this page: http://endless-sphere.com/forums/viewtopic.php?f=2&t=16535&start=45
Mine uses a cheap MY1018 motor, but has worked very well for the last couple of years. It's a real pleasure zipping up through the gears with it. The drawback is that it sounds a like a very large mosquito, so I want to try using a hub motor instead. I was all set to do this a year or so ago using one of the little nano motors, but then there was a string of reports of reliability problems so I shelved the idea. I'm not up to date with the what's come on the market since then, so I'm hoping you can help me with some recommendations. I'm looking for a small, geared hub motor, with a weight no more than 3.5 kg and nominal power of 250W upwards. The main priorities are reliability and quiet operation. I've read various comments on the merits of steel gears versus nylon and I'm still not decided, but it would be great if the motor was available with both. The Bafang motors seem to get good reviews, but are there any others? I'm looking for a rear motor to take a threaded freewheel and will be running a 36V pack.
