NZN Labs, Inc., had pre-production prototypes of their Lit Pro units at Glen Helen on a few riders. It measures advanced metrics like speed, heart rate, airtime and g-force data. The enclosure here will be thinned out a bit, and still needs a functioning port for charging and download. You can check more on this startup at their web site (http://www.litpro.mx) or Facebook page (https://www.facebook.com/nznlabs).
