Age: 50, Roads: paved flat with 20-30% hill grade, climate: tropical. I'm new to the EUC world. My 1st EUC is a KS14D, which I got because I wanted to learn and wasn't sure if I will get into riding a EUC. After only a month, I was already looking into a new, bigger wheel. I choose the KS16S because it had the range, power, speed and quality build reputation and a price I can afford. It is perfect for commuting/last mile, quick errand runs and cruising around. The weight is not to bad and the trolly handle is awesome. I got the quick charger so charging is cut in half.
