Nowashocki

Nowashocki is an excellent suburban commuter. It passes cars easily, sucks up potholes, and handles well. The regen (typically 5-10%)doesn't really add much range because the best range is obtained when riding like a hypermiler - decelerating so gently the regen doesnt kick in. But who wants to do that? This is about fun and I love regen because I can approach a corner fast, back off the throttle, and it feels like the major compression braking of a 4-stroker! Motorcyclists NEED this feeling! The entire system has worked flawlessly so far.
