Certified green, the X-Treme XM-3100 Moped 2009 is one of the latest additions to the company’s line. Powered by high- powered Lithium batteries and a 3100 Watt rear hub motor, the XM-3100 is fast and light, hits speeds of about 50MPH, and can run up to 85 miles on a single charge. Since its batteries are stored low, this X-Treme moped’s center is low to the ground, which offers its riders more stability and control. Not only is it quick, but it can also stop on a dime, thanks to rear hydraulic disc brakes, plus it’s easy to drive, as it comes equipped with automatic transmission. X-Treme.
