Yep, it is the 328rpm motor (designed for 20" wheel), so it likes to go fast. No load speed is 29mph I think. I doubt it has the power to do more than 20mph on its own, but with my legs providing 50% of the power, we are happy doing 25mph together. ;-)
Its a single speed/fixed gear bike. Originally I used it fixed gear to commute, but obviously switched to single speed when I added the motor. One happy benefit is that its the only high end frame I've seen with beefy dropouts. Geared road bikes have some wimpy drop outs, but a Track Bike vertical drop out is pretty beefy. I bought a '94 steel Specialized race bike to electrify it, but the dropouts are so scrawny that i was scared to electrify it. However, its such a sweet bike, I love riding it Au-Natural too much to put a motor on it.
First and only single speed and drop bar bike I've really ever seen in the DIY scene. I was a little nervous trying a single speed build, but looking at the engineering drawings it seemed doable - and worked out quite well.
