Despite the headline, this isn't really a story about superconductivity—at least not the superconductivity that people care about, the stuff that doesn't require exotic refrigeration to work.

This is Gear editor Julian Chokkattu's favorite scooter. The riding experience is powerful and smooth, thanks to its dual 350-watt motors and solid front and rear suspensions. The speed maxes out at 28 miles per hour (mph), which doesn't make it the fastest scooter on the market, but it has a good range. (Chokkattu is a very tall man and was able to travel 15 miles on a single charge at 15 mph.) Other Apollo features he appreciates: turn signals, a dot display, a bell, along with a headlight and an LED strip for extra visibility.
