Nimble and bold, you will love riding the brushed aluminum Genesis 500. Reaching speeds of up to 20 mph via the powerful 500-watt motor mounted in the rear wheel, which delivers 720 watts at peak, this is the synthesis of high-energy efficiency and top-level performance. Simply use the half-twist throttle to activate the "power-on-demand" propulsion system. The energy efficient 38-volt, 9-amp, high-capacity advanced lithium ion battery (LiFePO4) enables you to ride distances of 25 to 30 miles per charge. Thanks to the SRAM X5/X7 Twist 8-speed shifter and Avid BB5 disc brakes riders are certain to enjoy a smooth and effortless ride even while offering the option of pedaling for exercise. Continental Double Fighter 26-inch tires add to the winning look and performance for light off-roading and city riding. Storage is easy thanks to the aircraft-grade aluminum alloy folding frame. The Genesis 500 is easily adjustable for virtually any-sized rider and makes for great, green energy transportation.
