Anyone have experience with the Segway Ninebot external battery for $250?
Claims: “compatible with the Ninebot KickScooter by Segway ES1 & ES2 & E22. Increases the range of the ES1, ES2 & E22 to 27.9, 28 and 27 miles respectively. It also increases the speed of the ES1, ES2 & E22 to 15.5 mph, 18.6 mph and 15.5 mph respectively.”
I really like the E22’s FlatFree Tire Technology (unlike common solid tires, it fills the inner tube with a new PU foaming material) and haven’t come across other scooters with this type of maintenance free tire. I wish the E22 was just a tad faster, so the external battery is tempting if the claims are accurate, but it’s also rather pricy if the boosted speed doesn’t live up to the claims (E22+ext.battery=~$750). Any thoughts/advice would be awesome. Thanks y’all
