Tilting trikes seem to be gathering momentum. Piaggio’s MP3 has been on the market for a while, Yamaha’s Tricity is available in Europe, we reported on the Tilting Motor Works full-size Harley-Davidson earlier this year, and now comes Sway Motorsports tilting electric trike. In addition to its ability to lean, the Sway’s other advantage is its lithium-ion battery location below the chassis and between the front and rear wheels. According to Sway’s CEO and chief engineer, Joseph Wilcox, its first model will be available next spring for $8,700. Top speed is a claimed 55 mph, with a 35-mile range, and a four-hour charge time to 80% from a standard wall socket.
