There was a project created over on ES which used an AC Induction motor of the same category and they used an inverter (the sort of thing you plug into your cigarette lighter in the car) to take a 12VDC battery up to 120VAC. It worked... it was really, really heavy, but it worked.
The Tesla Roadster uses an Induction motor and over a year ago I was all excited about the idea of doing it for ebikes, but Induction motors seem to find their efficiencies when you get up into the 100hp range. Below 100hp and it's hard to get above about 80% efficiency. By contrast the Halbach type CSIRO motors can reach near 96% efficiency and with far less weight.
To enhance efficiency I looked into Six Phase power as one way to boost performance and I actually bought a dishwasher motor and began to convert it, but the math just doesn't add up on these things. It's a lot of work to go backwards technically. (however the wider powerband of induction motors is appealing... you can get full power over an rpm range that is twice of a permanent magnet motor)
High powered Neodymium magnets combined with a Halbach array configuration Axial Flux motor seems to be the most high tech solution for an ebike and while we're not there yet it's the way we are being pointed to based on the facts.
