The UltraTrek 'King E-Cheetah' is one of the wildest electric bicycles on the market, and it isn't meant for streets. The motor is quite the large and powerful machine, so you need a proportionately good battery to keep it running. The Sony/Panasonic 72-volt, 60-amp-hour battery should do the trick- it allows for a top range of 80 miles (129 kilometers) under optimum conditions.
The frame is made of steel and has a KK suspension fork with 150 millimeters (5.9 inches) of travel, adjustable, and lockout. That rear shock is an UltraTRX component that can handle up to 1,000 pounds (453 kilograms). Add a single-speed transmission, tubeless motorcycle wheels, and 203-millimeter (8-inch) brake rotors, and you've got a 98-pound (44-kilogram) chunk of off-roading steel.
If that isn't enough to pique your interest, let us tell you about the option of adding a solar panel attachment that allows you to fully charge your battery in as little as 7 hours? Oh, and of course, if you want to go even further, add goodies like cargo bags and a rear cargo rack. For only $5,000 USD, the UltraTrek King E-Cheetah offers an amazing value for anyone looking for a powerful and fast electric vehicle.
