I've been perving on these things for a while now. a little pricey, but the rep is good, and everything looks to be well-finished and quality.. I've been trying to think of a good way to mount the motor-drive sprocket to the rear wheel, just for something to think about when i'm bored. Sportsman's solution is the best i've seen so far, but it still seems to be a strain on the spokes. Someone needs to make a dedicated hub for these things....
If only i had the spare cash, i'd love to build one. How do y'all think they'd perform with a rigid front end?
