http://urbanscooters.com/cgi-bin/urbanscooters/XB-502.html The X-Treme XB-502 is an electric bike that looks like a sleek, trendy electric moped. The XB-502 can be ridden like a standard bike, operate on one hundred percent electric power, or any combination of the two. The X-Treme XB-502 is loaded with nearly all of the same features you find on an electric moped at a fraction of the cost! Explore the standard feature list, it's beyond impressive. The 500 watt motor gets you up to 20 mph for up to 25 miles on a single charge. It puts out ample power to take medium sized hills. Better yet, while you have to register and hold a driver's license to operate a moped, the XB-502 is classified as an electric bicycle. The "electric bicycle" classification allows you to operate it without registration or a driver's license in most states (please contact the DMV to check the laws in your area before purchase). The XB 502 electric bike is environmentally friendly, noise-free, and operates on pennies a day. Electric bikes offer commuters a great way to bypass high prices at the pump.
