U-MAX MEDIUM DUTY IV GAS
TRANSPORTATION VEHICLE

When your need calls for extra-heavy load capabilities the all-new Medium Duty IV is your clear choice.

Power comes from either a 357cc four-stroke engine or a super powerful 48-volt electric system with 8 6-volt batteries and a large 400-amp controller.

Both are capable of carrying up to 800 pounds in the roto molded cargo box and 4 people. In addition, the new Medium Duty IV comes standard with a host of features including four-wheel brakes, streamline headlights and a 12-volt DC accessory outlet.
