Altered/Exkate electric skateboards/longboards are not known for their turning radius (it's HUGE), their weight (the one we used was 48 pounds stock!), nor their performance (1, yes ONE, wheel drive). In fact, about the only thing they are known for is being one of the first companies to produce electric skateboards/longboards. So we decided to make it better. The further we went, the more we realized we could have started with a deck and built up; thus, I will endeavor to make this Instructable useful to both types of builders.
CIM motors have been without a cheap, easy, and compact gear-reduction drive-train since their beginning. Now the wait is over. Read on!
The team was part of MIT's Edgerton Center Summer 2010 Engineering and Design Class, a month-long class where high school students learn and apply real-world engineering skills to various projects.
