Zero is the Apple of electric motorcycles. The Santa Cruz, Calif.,-based company’s bikes coast out of the factory in gleaming perfection with control software that has been optimized for safety and performance. And, as with iPhones, the source code remains a company secret. Gearheads who like to know every detail of how their machines work or want to modify them either have to jailbreak their devices or start from scratch. They can turn to outside sources but, again, the only option is to buy a motor controller kit from a company that has made all of the configuration decisions in advance.
