I just signed up, now that I have completed the build of my electric bike Crystalyte Phoenix Brute motor kit from electricrider.com. I'm hoping to find info on adding disk brakes, and learning about your experiences in building and using similar conversion kits. This is a great 48V motor that gets me to 25mph quietly in 11 seconds, and beats the Southern California hills around me into submission, while letting me get as much exercise as I choose. Later I hope to post a photo or two. Hoohaah!
