Valtinsu EM-5 Ultra

The Valtinsu EM-5 Ultra is the 72V flagship of the EM-5 pit-bike-style electric dirt bike line, built on the same compact 14-inch front / 12-inch rear off-road chassis as the base EM-5 but upgraded to a 72V system. It uses a geared brushless motor rated at 7000W peak with 275 Nm (203 lb-ft) of torque, reaching a top speed of about 56 mph (90 km/h) and a claimed range of up to 75 miles. The 72V 25Ah Samsung-cell battery, controller, BMS, and charger are all factory-matched for the higher voltage, and the bike adds a reverse gear, three ride modes, and a 45-degree climbing claim. Sold as an adults-only (18+) off-road machine.
