Met these people here at the eGrandPrix event... It's a hub motor meant for motorcycle use. It's much bigger than typical bicycle hub motors, and is sized to fit motorcycle swingarms. He says it'll require some kind of torque arm to help adapt it to the specific swing arm you have.
Interesting thing is that Crystalyte did the motor design for him. It took 6 months of back and forth to get what he wanted.
At the show he has it mounted in ... geez, these lean over the handlebar motorcycles all look alike to me. Anyway it's in one of those racer style bikes. But it's just a demo bike. I took it for a spin and it's pretty powerful. Couldn't really let it loose in the parking lot however.
He plans to sell it as a kit ... uh, didn't ask 'when'.
