GMCSetup a couple of people in San Rafael with e-bike kits recently.  Here’s the comments they emailed to us:

“Doug, to say it is life changing is not an overstatement.”

“Doug, thank you again for all the work you put into my GMC bike.  I took it for a quick ride yesterday and I have to say, the 48 volt setup on this bike makes for quite an exhilarating ride :).”
