What do you think of this motor?

How can it accept from 24 volts to 240 volts? What should I check to see if it is durable. The size and weight are right for what I am thinking of doing - adding to a folding bike.

Transmag has been around for a long time. They make several models. Their office is close to where I live. It's not a bad motor if you get the one with an external controller. It is similar to the Kollmorgen and BMC motors. I think you could find a BMC motor for less $.

If you are interested, I would suggest contacting Thunderstruck Motors. I think that's the only place you could buy one from. http://www.thunderstruck-ev.com/

They have tested them extensively and can tell you more about the performance.
