Hi all, First post here :-) I just got my shiny new Solowheel Xtreme a week ago or so and had so much fun last week learning to ride it -- Later I'll do a review. Anyway, I was just wondering about the energy efficiency of using a Solowheel for my commute and compared against a bunch of regular and electric cars -- nice, a EUC is about 300 times more efficient than a Hummer and about 32 times more efficient than a Nissan Leaf :-)   BatteryRangeEnergy EfficiencyCarMPGkwhmileskwh/100miHummer 20131
