New Belt Drive

Has anyone tried the 4G T Belt Drive kit from bicycles-engines yet?
Just wanting some info on how well the belt holds up.

The kit you are asking about is still very new and there aren't any reports that I have read that the belt has been a problem. The one thing about them that you need to very aware of is the overall width of the motor and the primary reduction belt drive is almost 12 ins. While this width is not a problem with a rack mount set up it does make frame mounting in the forward triangle harder/more awkward.
